Want a piece of one of Houston’s most promising biotech companies? On January 31, FibroBiologics will begin the trading of its common stock on the Nasdaq stock exchange.

While most labs in the realm of regenerative medicine are focused on stem cells, FibroBiologics has bet on fibroblasts as the secret to treating myriad ailments. Fibroblasts, the most common type of cell in the body, are the primary cells that compose connective tissue.

Interested investors can find a prospectus to peruse before taking the leap. FibroBiologics filed with the U.S. Securities & Exchange Commission (SEC) on November 7, 2023. In September, FibroBiologics CEO Pete O’Heeron told InnovationMap, “I think what we're going to see is that fibroblasts are going to end up winning... They're just a better overall cell than the stem cells.”

O’Heeron was first exposed to the possibilities of fibroblasts as a means of regrowing discs in the spine. Since starting the company in 2008 as SpinalCyte, O’Heeron and FibroBiologics have organically written and filed more than 320 patents. Potential treatments go far beyond spinal surgery to include wound care, cancer, and multiple sclerosis.

According to O’Heeron, the goal in going public is to raise capital for human trials.

“We’ve had really fantastic results with animals and now we’re ready for humans,” he explained in September. “We've done small human trials, but we haven't done the large ones that are going to get the commercialization approval from the FDA.”

FibroBiologics is growing with impressive speed. O’Heeron told us that he is hiring as quickly as he is able to find qualified scientists with the expertise to do the one-of-a-kind work required. The company opened a new lab last fall at the UH Technology Bridge, Newlin-Linscomb Lab for Cell Therapies. With its new status as a publicly traded company, FibroBiologics is primed to break even more ground.

Pete O’Heeron wants you to know that “Bohemian Rhapsody” was originally released as a B-side. What does this nugget about Queen have to do with regenerative medicine? For O’Heeron and his company, FibroBiologics, it means everything.

That’s because most scientists consider stem cells the A-side when it comes to the race to curing disease. But FibroBiologics has set its sights on fibroblasts. The most common cell in the body, fibroblasts are the main cell type in connective tissue.

“Everyone was betting on stem cells, and we started betting on fibroblasts,” says O’Heeron, who started the company in 2008 as SpinalCyte. “I think what we're going to see is that fibroblasts are going to end up winning, there are more robust, more that are lower cost cell, they have higher therapeutic values, higher immune modulation. They're just a better overall cell than the than the stem cells.”

Since a neurosurgeon and a dermatologist first introduced O’Heeron to the idea of using fibroblasts to regrow discs in the spine, the company has expanded its reach to include promising treatments for multiple sclerosis and cancer and in wound care. Imagine a world where doctors lay fibroblasts directly onto surgical incisions after surgery, cutting the time for healing in half.

FibroBiologics has organically written and filed more than 320 patents.

“It's quite a unique situation. I don’t think that in other areas of science that you have such a wide open area to go out and patent. It's just it was a brand new area nobody had been working on,” O’Heeron explains.

And soon, investors will be able to own a stake in the impressive work being forged in Houston. FibroBiologics, previously FibroGenesis, was formed in order to go public in a direct NASDAQ listing. The goal is to access the capital necessary to go to human trials. Earlier this year, the company also launched a crowdfunding campaign.

“We’ve had really fantastic results with animals and now we’re ready for humans,” says O’Heeron. “We've done small human trials, but we haven't done the large ones that are going to get the commercialization approval from the FDA.”

With that in mind, the company just signed a deal with University of Houston’s Innovation Center. On Thursday, September 7, FibroBiologics will dedicate the Newlin-Linscomb Lab for Cell Therapies in the UH Technology Bridge. The new lab is named for former player and color commentator for the Houston Rockets, Mike Newlin and his wife, Cindy, as well as Pam and Dan Linscomb, a founding partner of Kuhl-Linscomb, one of the largest wealth management companies in Houston.

Other big local names newly attached to the company are astronaut Kate Rubins and Elizabeth Shpall, the director of the cell therapy laboratory at MD Anderson Cancer Center. Both have joined FibroBiologics as members of its scientific advisory board.

To fill the lab, O’Heeron says that he is adding to his team as quickly as he is able. The barrier is the fact that there are few, if any people in the world with the exact qualifications he’s seeking.

“Anytime you're breaking new scientific ground, you can't really just go out and recruit someone with that background because it really doesn't exist,” he says. But he is willing to teach and challenge scientists who are the right fit, and is hoping to expand the team in the new lab.

But like Queen did in 1975, FibroBiologics is pioneering a category of its own. And that’s something worth betting on.

Innovative Houston lab works with 'ghost hearts' to study impact of regenerative medicine

stem cell magic

Ask any high achiever and they’ll tell you — failure is the path to success.

As Camila Hochman-Mendez puts it, “I’m like Thomas Edison, right? I know a thousand ways of how not to create a lightbulb.” But she’s not really talking about electricity. Hochman-Mendez is director of Regenerative Medicine Research and the Biorepository Core at Texas Heart Institute.

Hochman-Mendez follows another pioneering woman in the role, Doris Taylor. The younger scientist took on the prime job when Taylor left in 2020. By then, Hochman-Mendez had been at The Texas Heart Institute for three years, moving from research scientist to assistant director in just four months.

Regenerative Medicine is every bit as exciting as it sounds. At Hochman-Mendez’s lab, her team creates ghost hearts — organs from which all cells are scrubbed, leaving collagen, fibronectin, and laminin in the shape of the formerly beating ticker. The goal is to use the decellularized organs as protein scaffolds that, once injected with stem cells, will once again contract and pump blood.

Hochman-Mendez cautions that we are still years away from that point, but her lab is working hard to get there.

“The ultimate goal is to develop functional hearts that can be used for transplant,” says Hochman-Mendez.

Those hearts would be made from the patient’s own cells, avoiding organ rejection, which the scientist says is essentially trading one disease for another. But she is realistic about that fact that there are many barriers to her success.

“It does come with a lot of technical challenges,” she says.

These challenges include the simple number of cells that billions, and potentially hundreds of billions of cardiomyocytes are needed to recreate a human heart. The necessary protocols, Hochman-Mendez explains, are extremely costly and labor intensive.

It also takes 60 days for the cells to reach a maturity at which they can function. The lab recently received a pair of grants targeted at creating bioreactors that can be reliable for at least those 60 days.

The third major issue facing the Regenerative Medicine lab is contamination.

“It needs to be very sterile,” says Hochman-Mendez. “It needs to be so clean that if you have one tiny bacteria there, you’re screwed.”

Fortunately, the scientist says that her favorite hobby is computer programming. She and a physician colleague have created a robotic arm that can help to prevent the contamination that often stemmed from humans manually injecting stem cells into the decellularized organs.

This not only works towards solving the contamination problem, it also allows the team to more accurately distribute the cells that they add, using an injection map. To that end, she is producing a three-dimensional model of a protein scaffold that will allow her team and other scientists in the field of regenerative medicine to understand how the cells really disperse when they inject them.

When will her lab produce working hearts?

“I try to be very conservative on timing,” she says.

She explains that it will take significant leaps in technology to make a heart mature to the level at which it’s usable for an adult body in 60 days.

“That’s magic and I don’t believe in magic,” she says, but adds that she hopes to have a prototype ready to be tested in five years.

Hochman-Mendez does this all with a small team of nine researchers, most of whom happen to be female.

“The best candidates are the ones that I select," she says. "The majority are females. I think it’s a mix of trying to be very unbiased, but I usually don’t even look at the name before looking at the CV to preselect the people that I interview.”

And together, Hochman-Mendez are making medical history, one success-spawning failure at a time.

Houston biopharma company launches equity crowdfunding campaign

money moves

A clinical-stage company headquartered in Houston has opened an online funding campaign.

FibroBiologics, which is developing fibroblast cell-based therapeutics for chronic diseases, launched a campaign with equity crowdfunding platform StartEngine. The platform lets anyone — regardless of their net worth or income level — to invest in securities issued by startups.

The funding, according to a press release, will be used to support ongoing operations of Fibrobiologics and advance its clinical programs in multiple sclerosis, degenerative disc disease, wound care, extension of life, and cancer.

"We're excited to partner with StartEngine on this campaign. StartEngine has over 600,000 investors as part of their community and has raised over half a billion dollars for its clients," says FibroBiologics' Founder and CEO Pete O'Heeron, in the release.

"This is an exciting time at FibroBiologics as we continue progressing our clinical pipeline and developing innovative therapies to treat chronic diseases," he continues. "This new funding will fuel our growth in the lab and bring us one step closer to commercialization."

The campaign, launched this week, already has over 100 investors, at the time of publication, and has raised nearly $2 million, according to the page. The minimum investment is set at around $500, and the company's indicated valuation is $252.57 million.

In 2021, FibroBiologics announced its intention of going public. Last year, O'Heeron told InnovationMap on the Houston Innovators Podcast of the company's growth plans as well as the specifics of the technology.

Only two types of cells — stem cells and fibroblasts — can be used in cell therapy for a regenerative treatment, which is when specialists take healthy cells from a patient and inject them into a part of the body that needs it the most. As O'Heeron explains in the podcast, fibroblasts can do it more effectively and cheaper than stem cells.

"(Fibroblasts) can essentially do everything a stem cell can do, only they can do it better," says O'Heeron. "We've done tests in the lab and we've seen them outperform stem cells by a low of 50 percent to a high of about 220 percent on different disease paths."

Houston biotech company gets FDA greenlight to move forward with COVID-19 stem cell treatment

coronavirus cure?

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.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
