A Houston-based biotech company announced last week that it has gotten the approval it was seeking from the U.S. Food and Drug Administration to continue testing its COVID-19 treatment that uses stem cells.

Celltex has received approval from its Investigational New Drug application, or IND, to look into stem cells — specifically Autologous Adipose Tissue-Derived Mesenchymal Stem Cells, or AdMSCs — and their effect on COVID-19 patients.

"The FDA's approval of our IND is not only a critical milestone for Celltex, but also for everyone who has been affected by COVID-19," says David G. Eller, Celltex chairman and CEO. "I am optimistic that our findings will result in favorable outcomes that will improve lives today and for generations to come."

Celltex has been in the stem cell business for nearly a decade and has treated patients with debilitating diseases like multiple sclerosis, Parkinson's, rheumatoid arthritis, and more. Eller says he's been considering how Mesenchymal Stem Cells, or MSCs, could be used amid the pandemic.

"Throughout the entire pandemic, MSCs have shown promise for combatting symptoms and complications associated with COVID-19, and as the nation's leading commercial MSC banking and technology company, Celltex has the unique ability to transition these initial findings into a clinical trial," Eller says.

The FDA clearance will allow for a phase two trial "that will evaluate the safety and prophylactic efficacy of AdMSCs against COVID-19," according to the release. There will be 200 patients across multiple centers that will be involved in the placebo-controlled study.

Celltex offices out of the Galleria area and has laboratory operations of its wholly-owned Mexican subsidiary are located in Hospital Galenia in Cancún, Quintana Roo, Mexico. Last year, Celltex planned an expansion into Saudi Arabia and also has a presence in Europe.

5 Houston biotech companies taking health care to new levels

The future is now

Houston is the home of the largest medical center in the world, so it comes as no surprise that the Bayou City is also home to breakthrough technologies. Here are five Houston companies developing some of this biotech advancements.

Moleculin Biotech Inc.

Immunotherapy and personalized medicine get all the headlines lately, but in the fight against cancer, a natural compound created by bees could beat them in winning one battle.

In 2007, chairman and CEO Walter Klemp founded Moleculin Biotech Inc. as a private company. The former CPA had found success in life sciences with a company that sold devices for the treatment of acne. That introduction into the field of medical technology pushed him toward more profound issues than spotty skin.

"Coincidentally, the inventor of that technology had a brother who was a neuro-oncologist at MD Anderson," Klemp recalls.

The since-deceased Dr. Charles Conrad slowly lured Klemp into what he calls the "cancer ecosphere" of MD Anderson. In 2016, the company went public. And it looks like sooner rather than later, it could make major inroads against some of the toughest cancers to beat. Read the full story here.

Cavu Biotherapies

Breakthrough biotech doesn't have to just be for humans. More than three years after its founding, Houston-based veterinary biotech company CAVU Biotherapies' had its first cancer patient: a black Labrador in Pennsylvania diagnosed with B-cell lymphoma.

Dr. Colleen O'Connor, CEO and founder of CAVU Biotherapies, established the company in July 2015 with a goal to help pets live longer post-cancer diagnoses. O'Connor, who earned a PhD in toxicology with a specialty in immunology, has more than a decade of hands-on experience researching cancer treatments.

"Our goal is to scale up and be able to increase our dogs' qualities of life with us," O'Connor said. "We want to keep families intact longer and we want to be able to modernize cancer care for our animals." Read the full story here.

Innovative Biochips

Innovative Biochips, a Houston-based biotechnology company, is one step closer to commercializing technology that the company hopes will provide an opportunity for researchers to detect diseases earlier.

The company was founded three years ago by Dr. Lidong Qin, a professor at the Houston Methodist Research Institute's department of nanomedicine. He launched iBiochips as an independent faculty startup that licensed technology from Houston Methodist. Qin says he wanted to engineer and manufacture devices that focus on revolutionizing single-cell isolation and genetic analysis. Read the full story here.

Celltex

A Houston stem cell company is making strides in regenerative medicine. Celltex's treatment has been proved effective with its patients. Eighty-three percent of multiple sclerosis patients have reported improvement of symptoms specific to their disease, as have 73 percent of Parkinson's sufferers. But the staggering fact is that 100 percent of 58 respondents with rheumatoid arthritis say they have benefited.

David Eller, chairman, co-founder and CEO of the company, also recently announced the company's expansion to Saudi Arabia. Read the full story here.

Ridgeline Therapeutics

Stan Watowich pictures a world where elderly people have the same healthy muscles they had at a younger age. Watowich is CEO of Ridgeline Therapeutics, a spin-off company of the University of Texas Medical Branch in Galveston where he is an associate professor of biochemistry and molecular biology, and he wants to make it clear that he is not going to cure aging.

"You and I are still going to get old," he says. "But we have our hopes that as we get old our muscles will stay healthy."

He's talking about the drug candidate, RLT-72484. It has been shown to reactivate muscle stem cells and regenerate skeletal muscle in aged laboratory mice. Read the full story here.

Houston biotech company plans expansion into Saudi Arabian market

On the move

A Houston company that uses stem cell technology to treat patients suffering from degenerative diseases is taking its patented technology to another continent.

Celltex Therapeutics Corp. has entered a memorandum of understanding with Saudi Arabia's Research Products Development Company. As a part of the partnership solidified by the MOU, Celltex will open an office in Riyadh, Saudi Arabia, later this year. The new office will aid the commercialization of Celltex's technology and expand the company's presence to Saudi Arabia.

"We are honored to forge a relationship with Saudi Arabia," says David G. Eller, CEO and chairman of Celltex, in a release. "Our collaboration with this first-rate global cohort furthers our commitment to initiating breakthroughs in regenerative medicine, and our presence in Riyadh will further expand our opportunities to improve the quality of life of those in need."

The MOU is a part of the country's effort to diversify the economy that's been dominated by oil and gas, the release says. As a part of Saudi Arabia's National Industrial Development and Logistic Program, Celltex and other United States companies were invited to Riyadh to sign MOUs in January, which resulted in billions of dollars in Saudi investment, per the release.

On February 4, the two parties reconvened at Celltex's office in Houston. The group included top Saudi dignitaries, Abdulmohsen Almajnouni, CEO of RPDC, as well as others.

"We are excited to explore business opportunities with Celltex, a biotechnology company with the innovative proprietary technology, patents and know-how for the cultivation and therapeutic application of stem cells," Almajnouni says in the release.

Celltex currently extracts patients' stem cells at various partner facilities across the United States, but implementation happens at a hospital in Mexico, due to FDA regulations and red tap. However, Eller doesn't foresee this being the process forever.

"We have very good relations with the US FDA," he says in an InnovationMap article. "They are very interested in what we know. Our approach is really is very progressive and we've grown every year."

The company's treatment has been proved effective with its patients. Eighty-three percent of multiple sclerosis patients have reported improvement of symptoms specific to their disease, as have 73 percent of Parkinson's sufferers. But the staggering fact is that 100 percent of 58 respondents with rheumatoid arthritis say they have benefited.

Marla Murphy didn't feel like she was doing enough to promote health and wellness with her platform, The Blonde Pantry. So, she expanded it to incorporate locally sourced produce and easy-to-make recipes she gets ready every weekend to deliver to her members by Monday.

"It's not about selling meals and moving on, I want this to be a lifestyle company that is really founded and has deep roots in Houston," says Murphy in a InnovationMap story.

Murphy tells InnovationMap that in the next year she hopes to expand into the retail space and find a bigger commercial kitchen to function as their own. She also hopes to partner with companies outside of food and continue to nourish lives in someway.

David Eller, chairman, co-founder and CEO of Celltex

Stem cell treatment is personal to David Eller, chairman, co-founder and CEO of Celltex. Eller had the treatment in hopes of resolving pain from a college football injury.

"I would go to work and put four to six Advil in my pocket," Eller says in an InnovationMap story about Celltex's technology. Within months, he stopped needing those pills.

Houston-based Celltex tracks its progress with its patients. Eighty-three percent of multiple sclerosis patients have reported improvement of symptoms specific to their disease, as have 73 percent of Parkinson's sufferers. But the staggering fact is that 100 percent of 58 respondents with rheumatoid arthritis say they have benefited.

Katharine Forth has used a technology she developed with her colleague at NASA to measure balance in astronauts to create a device that any terrestrial human can now use from the comfort of their own homes.

"The machines typically used for balance measurement can be as large as a telephone booth, so we invented a new way to measure postural control using a much smaller mechanism that fit inside a moon boot," Forth says in an InnovationMap article about Zibrio, The Balance Company. Zibrio, The Balance Company.

Zibrio is now a finalist for the 2019 SXSW Pitch in the health and wearables category and will take its balance technology to the stage in March.

Regeneration nation

The medical community has former governor Rick Perry to thank for a major stride in regenerative medicine.

"He had just gotten elected for the last time and he wanted to leave a legacy. He was tired of people going to Japan or Germany when they needed stem cells," recalls David Eller, chairman, co-founder and CEO of Celltex.

That was 2011, the year that the former president of Dupont Pharmeceuticals-Europe and orthopedic surgeon Dr. Stanley Jones incorporated as Celltex. Perry got the law passed to make it legal to harvest his stem cells, and Jones implanted them while the governor was under the knife for a spinal fusion surgery.

Perry resigned from the Celltex board in 2017, but the truth is, the company no longer needed his clout. Just a year after its debut, the company had in excess of 200 clients, each paying a banking enrollment fee of $6,500. Now, there are close to 1,300.

From research to recovery
Eller is originally from Houston, and he says his hometown is the ideal home base for the company, with its access to the world's largest medical center. The Galleria-area office and lab employ 35 people, with about 50 workers worldwide.

Close to the same time that his friend Perry received his stem cells, Eller also had the treatment in hopes of resolving pain from a college football injury.

"I would go to work and put four to six Advil in my pocket," the CEO recalls.

Within months, all of them remained in his pocket.

But others have had even more dramatic results. Celltex checks in with patients three, six and nine months after their treatments to find out how they're doing. Eighty-three percent of multiple sclerosis patients have reported improvement of symptoms specific to their disease, as have 73 percent of Parkinson's sufferers. But the staggering fact is that 100 percent of 58 respondents with rheumatoid arthritis say they have benefited.

Implementation and the FDA
Celltex's chief scientific officer, Dr. Jane Young, co-authored a study of two severe juvenile rheumatoid arthritis patients whose conditions didn't respond to standard treatments. After trying stem cells, both reported marked improvement in autonomic nervous system and immune function.

Stem cells are gathered through a patient's fat, which can be extracted at any of the 80 facilities around the country that partner with Celltex. The fat is processed at the Houston lab, where processing takes 30 to 35 days.

"We have 15 billion cells in process each day," says Erik Eller, the company's vice president of operations, clarifying that some clients' cells grow faster than others'.

It takes 14 days to come out of cryostasis and leave the lab. From there, the stem cells travel to Hospital Galenia in Cancun, Mexico for implantation, since the FDA categorizes stem cells as a drug if they have expanded as they do at Celltex. That means that a patient cannot use his own stem cells in the United States without a clinical trial. To circumnavigate the red tape, Celltex has simply partnered with the luxurious Mexican hospital.

This is currently the company's biggest challenge, says David Eller, but one he expects to overcome.

"We have very good relations with the US FDA," he says. "They are very interested in what we know. Our approach is really is very progressive and we've grown every year."

Ultimately, Eller hopes to be able to implant stem cells in the United States. But the company's foreign growth is a good start. Celltex is now operating in the Bahamas and is hoping to add Australian extraction facilities sometime this year. They are also in negotiations with a team from Saudi Arabia interested in expanding Celltex to the Middle East.

Other goals for Celltex include improvements both in the realms of sales and revenue and streamlining and improving the safety and efficacy of treatment. Research collaborations with Baylor College of Medicine and Texas A&M will help with the company's medical credibility. This all may help to convince the FDA to allow the Celltex to get a biologics license, the final proof that it is not a drug company. But no matter how it's categorized, Celltex is growing exponentially as its cells.

Rice University partners with astronaut foundation to offer new STEM scholarship

space scholars

Rice University has partnered with The Astronaut Scholarship Foundation (ASF) to offer a new scholarship opportunity for junior or senior STEM majors, beginning this spring.

The prestigious Astronaut Scholarship includes up to $15,000, mentorship, networking and a paid trip to the ASF Innovators Symposium and Gala. The scholarship is funded by the James A. Lovell Jr. Family Endowment, in honor of the late American astronaut and founder of the ASF.

“This scholarship opportunity represents an exciting new avenue for Rice STEM students to synthesize their experiences in courses and research and their commitment to advancing the public good as leaders in their field,” Danika Brown, executive director for the Center for Civic Leadership at Rice, said in a news release. “We are so grateful to the Lovell family and to the foundation for investing in Rice students, and we are confident that the foundation will be impressed with our nominees and that selected students will have a life-changing experience as astronaut scholars.”

The Rice Space Institute and the Center for Civic Learning recently hosted the ASF at the Ralph S. O’Connor Building for Engineering and Science.

At the ASF event, Jeff Lovell—son of James Lovell, who commanded Apollo 13 and flew on Apollo 8—announced the scholarship aimed at Rice STEM students. Charlie Duke, who served as spacecraft communicator for the Apollo 11 Moon landing and as the lunar module pilot for Apollo 16, also spoke at the event.

The ASF awarded 74 scholarships to students from 51 universities across the U.S. last May.

The ASF awarded its first seven $1,000 scholarships in 1986 to pay tribute to the Mercury 7 astronauts. It has since awarded more than $10 million to more than 850 college students.

So far, only students from Texas A&M University and the University of Texas at Austin have received the scholarship in Texas.

Houston hospital first in U.S. to use new system for minimally invasive surgery

sharper images

Houston’s Baylor St. Luke’s Medical Center has introduced an innovative new surgical imaging system that will allow surgeons to increase the number of minimally invasive procedures as well as reposition on the fly during operations.

Minimally invasive surgery has been shown across the board to improve patient outcomes with less chance of infection and shorter recovery times compared to traditional open surgery. However, the human body is not exactly easy to work on through small incisions, necessitating the development of state-of-the-art cameras and imaging technology to guide surgeons.

Enter GE HealthCare’s Allia Moveo, now a part of the Baylor St. Luke’s Medical Center operating room. Using cutting-edge technology, it uses the same high-definition imaging usually seen in the catheterization lab at speeds fast enough to respond to shifting surgical conditions. Its cable-free setup allows surgeons to switch positions much faster, and it features advanced 3D imaging that compensates for breathing motion and interference from metal implants.

Its design supports a range of cardiovascular, vascular, non-vascular, interventional and surgical procedures, according to CommonSpirit Health, a nonprofit Catholic health network, of which Baylor St. Luke's is a member.

“This innovative platform enhances how our clinicians navigate complex minimally invasive procedures by improving mobility, image clarity, and workflow efficiency. It strengthens our ability to deliver precise, patient-centered care while supporting our teams with technology designed for the evolving demands of modern interventional medicine,” Dr. Brad Lembcke, president of Baylor St. Luke’s Medical Center, said in a news release from Baylor and the Texas Heart Institute.

Baylor St. Luke’s is the first hospital in the U.S. to use the Allia Moveo technology. The definition and responsiveness of the new system allow surgeons to navigate the body with greater accuracy and smaller incisions, even for very delicate operations.

“Allia Moveo gives us the flexibility and image quality needed to manage increasingly complex minimally invasive procedures with greater confidence,” Dr. Gustavo Oderich, vascular surgeon and professor of surgery at Baylor College of Medicine, added in the release. “The ability to quickly reposition the system, obtain high-quality 3D imaging, and integrate advanced guidance tools directly into the workflow enhances procedural accuracy. This technology supports our mission to push the boundaries of what is possible in endovascular and interventional surgery.”

Houston clocks in as one of the hardest working cities in America

Ranking It

Houston and its residents are proving their tenacity as some of the hardest working Americans in 2026, so says a new study.

WalletHub's annual "Hardest-Working Cities in America (2026)" report ranked Houston the 37th most hardworking city nationwide. H-town last appeared as the 28th most industrious American city in 2025, but it still remains among the top 50.

The personal finance website evaluated 116 U.S. cities based on 11 key indicators across "direct" and "indirect" work factors, such as an individual's average workweek hours, average commute times, employment rates, and more.

The U.S. cities that comprised the top five include Cheyenne, Wyoming (No. 1); Anchorage, Alaska (No. 2); Washington, D.C. (No. 2); Sioux Falls, South Dakota (No. 4); and Irving, Texas (No. 5). Dallas and Austin also earned a spot among the top 10, landing as No. 7 and No. 10, respectively.

Based on the report's findings, Houston has the No. 31-best "direct work factors" ranking in the nation, which analyzed residents' average workweek hours, employment rates, the share of households where no adults work, the share of workers leaving vacation time unused, the share of "engaged" workers, and the rate of "idle youth" (residents aged 16-24 that are not in school nor have a job).

However, Houston lagged behind in the "indirect work factors" ranking, landing at No. 77 out of all 116 cities in the report. "Indirect" work factors that were considered include residents' average commute times, the share of workers with multiple jobs, the share of residents who participate in local groups or organizations, annual volunteer hours, and residents' average leisure time spent per day.

Based on data from The Organisation for Economic Co-operation and Development (OECD), WalletHub said the average American employee works hundreds of more hours than workers residing in "several other industrialized nations."

"The typical American puts in 1,796 hours per year – 179 more than in Japan, 284 more than in the U.K., and 465 more than in Germany," the report's author wrote. "In recent years, the rise of remote work has, in some cases, extended work hours even further."

WalletHub also tracked the nation's lowest and highest employment rates based on the largest city in each state from 2009 to 2024.

Other Texas cities that earned spots on the list include Fort Worth (No. 13), Corpus Christi (No. 14), Arlington (No. 15), Plano (No. 17), Laredo (No. 22), Garland (No. 24), El Paso (No. 43), Lubbock (No. 46), and San Antonio (No. 61).

Data for this study was sourced from the U.S. Census Bureau, Bureau of Labor Statistics, U.S. Travel Association, Gallup, Social Science Research Council, and the Corporation for National & Community Service as of January 29, 2026.
