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.

Houston doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
