Stem Cell Therapy in Houston: What’s Legal, What’s Not, and What’s Actually Available Today

Written by Dr. Joel Cherdack, President of Houston Regenerative Medicine

---

If you’ve researched stem cell therapy in Houston, you’ve likely encountered wildly conflicting information.

Some clinics claim everything is FDA-approved. Others insist you must travel to Mexico for any real treatment. You’ll see exosomes marketed aggressively by one provider, while another tells you they’re completely illegal.

Patients are confused—and understandably so.

Both the FDA and the State of Texas have updated their regulatory guidance in recent years, but most clinics haven’t translated these changes into plain language. That leaves you sorting through marketing claims, trying to figure out what’s actually safe, legal, and available right now.

This guide will give you a clear roadmap. You’ll learn what regenerative treatments you can legally receive in a Houston clinic today, what requires international travel, and how to evaluate providers based on compliance rather than hype.

Let’s break it down in a way that’s easy to follow.

What Stem Cell Treatments Are Actually Legal in Houston Right Now?

Here’s the most important thing to understand upfront:

Stem cell injections are not FDA-approved for arthritis, orthopedic conditions, spine issues, hair restoration, cosmetic purposes, or anti-aging.

That statement surprises many patients—but it’s the regulatory reality.

However, the FDA does allow certain regenerative therapies in clinical settings when they meet specific criteria. This is where the confusion starts, because “not FDA-approved” doesn’t mean “illegal to offer.”

The 361 HCT/P Pathway: What Clinics Can Legally Use

The FDA permits clinics to use regenerative products that fall under the 361 HCT/P pathway. These are human cells, tissues, and cellular or tissue-based products (HCT/Ps) that meet strict requirements:

• Minimally manipulated: The tissue cannot be cultured, expanded, or significantly altered from its original form.
• Homologous use: The tissue must be used for its natural biological function (e.g., connective tissue to repair connective tissue).
• FDA-registered tissue bank: The product must come from a facility that meets donor eligibility and infectious disease screening standards.
• No drug-like claims: Clinics cannot market these products as cures or FDA-approved treatments.

When a regenerative product checks all these boxes, it can be used legally in a Houston clinic.

What You Can Receive Today (Without Leaving Texas)

At Houston Regenerative Medicine, we operate strictly within these FDA-allowed parameters. Here’s what’s currently available:

• Donor-derived umbilical cord tissue products (361 HCT/P compliant)
• Your own bone marrow or adipose (fat) stem cells (minimally manipulated, same-day processing)
• Platelet-rich plasma (PRP) from your own blood
• Exosomes as part of combined regenerative protocols (more on this below)
• Certain investigational therapies offered under proper oversight

These treatments are safe, transparent, and aligned with both FDA and Texas state guidelines.

If a clinic offers you “expanded stem cells” or “pure exosome injections” in Houston, that’s a red flag. Those treatments are not currently legal within U.S. clinics.

Understanding the FDA’s 361 HCT/P Pathway: What It Means for Patients

The term “361 HCT/P” sounds like regulatory jargon, but it’s actually your safety framework.

This designation tells you that a regenerative product has been evaluated by the FDA and determined to pose minimal risk—as long as it’s used correctly.

Why This Pathway Exists

The FDA created the 361 pathway to allow beneficial therapies to reach patients without requiring the full drug approval process (which can take 10+ years and cost billions of dollars).

The tradeoff? Strict limitations on how the tissue can be processed and used.

What “Minimally Manipulated” Actually Means

This is the most misunderstood requirement.

Minimal manipulation means the tissue’s original biological characteristics are preserved. For example:

• Allowed: Rinsing, sizing, or shaping tissue.
• Not allowed: Culturing cells in a lab to multiply them, adding growth factors, or genetically modifying cells.

Once a clinic cultures or expands your cells, the product becomes a 351 biologic—which requires FDA approval, clinical trials, and a completely different regulatory pathway.

That’s why expanded stem cells aren’t available in Houston clinics. No private clinic has FDA approval to offer them.

How This Protects You

The 361 pathway ensures:

• Traceable sourcing: Every donor is screened for infectious diseases.
• Consistent quality: Tissue banks must follow Current Good Tissue Practice (CGTP) standards.
• Transparency: Clinics must document what product they’re using and where it came from.

When you choose a provider that operates within this framework, you’re choosing accountability.

Are Exosomes Legal in Texas? The Real Answer

Exosomes are one of the most aggressively marketed—and most misunderstood—regenerative products.

Here’s the clear explanation.

What Exosomes Are

Exosomes are tiny vesicles (think of them as microscopic packages) that cells release to communicate with other cells. They contain proteins, lipids, and genetic material that may support tissue repair and reduce inflammation.

They’re naturally present in many regenerative tissue products, including umbilical cord tissue and amniotic fluid.

The Legal Reality

The FDA has not approved exosomes as a standalone drug for orthopedic use, cosmetic applications, or anti-aging.

That means clinics cannot legally offer a vial of “pure exosomes” as a primary treatment.

However—and this is where the confusion comes in—exosomes can be present in compliant 361 HCT/P tissue products, and they can be used as part of broader regenerative protocols when the overall treatment fits within FDA guidelines.

How We Use Exosomes at Houston Regenerative Medicine

We incorporate exosomes as part of combined regenerative therapies, not as standalone injections.

For example:

• Exosomes may be naturally present in the donor-derived tissue matrices we use.
• They may be included in systemic wellness protocols that combine multiple regenerative elements.
• They’re sometimes used alongside PRP or stem cells to support cellular communication.

We do not make drug-like claims. We don’t market exosomes as a cure. And we don’t offer “exosome-only” injections.

Our approach is compliant, responsible, and grounded in current scientific understanding—while staying safely within U.S. regulatory expectations.

Why Some Houston Clinics Treat Patients in Mexico

You may have seen marketing that says:

“We harvest your cells in Houston… but we treat you in Cancun.”

Patients often wonder why a Texas-based company would send them across the border for treatment.

Here’s the legal explanation.

What Texas Law Allows

Texas House Bill 5147 (passed in 2017) permits clinics to:

• Harvest your own cells (from bone marrow, fat, or blood)
• Perform minimal processing on those cells
• Store or bank your cells for future use

What Texas Law Does Not Allow

Texas clinics cannot culture or expand your cells for treatment.

Once your cells are expanded in a lab—meaning they’re grown to multiply their numbers—they become a 351 biologic, which requires:

• FDA approval
• Clinical trials demonstrating safety and efficacy
• A full drug regulatory pathway

Because no private clinic has that approval, they cannot legally offer expanded cells in the United States.

The Mexico Workaround

Some companies have partnered with offshore labs and clinics to perform the expansion step outside U.S. jurisdiction.

Here’s how it typically works:

1. You visit a Houston clinic for cell harvesting.
2. Your cells are sent to a lab in Mexico (or another country).
3. The lab cultures and expands your cells.
4. You travel to Mexico to receive the expanded cell treatment.

This model exists because the FDA’s authority ends at the U.S. border.

Important: This is not something any clinic operating solely in Texas—including Houston Regenerative Medicine—can legally offer.

If you want expanded stem cells, international travel is currently required. If you want treatments that can be performed entirely in Houston, you’ll be limited to minimally manipulated options (which is what we specialize in).

What Texas Law HB 5147 Actually Allows (and Doesn’t Allow)

HB 5147 is widely misunderstood, so let’s simplify what it actually permits.

What Texas Clinics May Do:

Harvest your own cells from bone marrow, adipose tissue, or blood
Process those cells minimally (e.g., concentrating, rinsing)
Use FDA-allowed regenerative tissue products (361 HCT/P compliant)
Provide certain investigational therapies under IRB-approved protocols
Store or bank your cells for future use

What Texas Clinics May Not Do:

Expand or culture stem cells
Offer standalone exosome injections
Use unapproved biologics from outside the U.S.
Market treatments as “FDA-approved” when they are not
Treat conditions beyond what federal rules allow

This is the legal reality for every regenerative medicine clinic in Houston—including ours.

Why These Restrictions Exist

The FDA’s primary concern is patient safety.

Expanded cells and standalone exosomes are considered drugs because they require significant lab manipulation. Without clinical trials proving they’re safe and effective for specific conditions, the FDA doesn’t allow them in U.S. clinics.

HB 5147 was designed to give Texas patients access to innovative therapies while still respecting federal safety standards.

What Regenerative Treatments Can You Receive at Houston Regenerative Medicine Today?

Here’s what most patients want to know:

“If I walk into your clinic tomorrow, what treatments can I legally receive without leaving Texas?”

Here’s the complete list.

1. Minimally Manipulated Donor-Derived Tissue Products

These are 361 HCT/P-compliant products sourced from umbilical cord tissue, amniotic fluid, or placental tissue.

What they contain:

• Mesenchymal stem cells (MSCs)
• Growth factors
• Cytokines
• Hyaluronic acid
• Naturally occurring exosomes

Common uses:

• Joint pain (knee, hip, shoulder)
• Spine conditions
• Tendon and ligament injuries
• Osteoarthritis

What makes them legal:
They come from FDA-registered tissue banks, meet donor screening requirements, and are minimally manipulated.

2. Your Own Bone Marrow or Adipose (Fat) Stem Cells

We can harvest stem cells from your own body and use them the same day.

The process:

• Bone marrow is typically drawn from the hip (iliac crest).
• Adipose tissue is harvested via a small liposuction procedure.
• Cells are concentrated and prepared in our clinic.
• The entire process takes 2–3 hours.

What makes them legal:
Same-day, minimally manipulated autologous (your own) cells are allowed under FDA guidelines.

3. Platelet-Rich Plasma (PRP)

PRP is derived from your own blood and contains concentrated platelets and growth factors.

The process:

• We draw a small amount of your blood.
• It’s spun in a centrifuge to separate the platelets.
• The concentrated plasma is injected into the treatment area.

Common uses:

• Tendonitis
• Ligament sprains
• Muscle injuries
• Hair restoration

What makes it legal:
PRP is considered minimally manipulated and is widely accepted in regenerative medicine.

4. Exosomes as Part of Combined Protocols

As explained earlier, we don’t offer standalone exosome injections.

However, exosomes may be included in:

• acCELLerate™ Therapy: Our proprietary combination of stem cells + PRP + naturally occurring exosomes
• Systemic wellness infusions that combine multiple regenerative elements
• Adjunct therapies used alongside other treatments

5. Investigational Therapies Under Proper Oversight

In some cases, we may offer investigational regenerative treatments as part of an Institutional Review Board (IRB)-approved protocol.

These therapies are conducted with full transparency, informed consent, and adherence to research standards.

How to Choose a Compliant Regenerative Medicine Clinic in Houston

Not all regenerative clinics operate the same way.

Some cut corners. Some make exaggerated claims. And some use products that aren’t FDA-compliant.

Here’s how to evaluate a provider.

Red Flags to Watch For

Claims of “FDA-approved stem cells” for orthopedic or cosmetic use
(These don’t exist. If a clinic says this, they’re either misinformed or misleading you.)

Offering expanded stem cells or pure exosome injections in the U.S.
(These require FDA approval and aren’t legal in U.S. clinics.)

Vague sourcing information
(You should know exactly where the tissue came from and which FDA-registered bank supplied it.)

Guarantees of specific outcomes
(No ethical provider can guarantee results for regenerative treatments.)

Pressure to “act now” or “limited availability” tactics
(Legitimate clinics don’t use high-pressure sales techniques.)

Green Flags: What to Look For

Clear documentation of tissue sourcing
(The clinic should provide donor eligibility forms and tissue bank registration.)

 Realistic expectations
(They should explain what the treatment may help with, not what it will cure.)

Transparent pricing
(You should know the cost upfront, with no hidden fees.)

Licensed, experienced medical staff
(Regenerative treatments should be performed by physicians or under direct physician supervision.)

Willingness to answer regulatory questions
(If a clinic gets defensive when you ask about FDA compliance, that’s a problem.)

---

Questions to Ask Before Your First Consultation

Before you commit to any regenerative treatment, ask these questions:

About the Product

1. “What specific product are you using, and where does it come from?”
   (They should name the tissue bank and confirm it’s FDA-registered.)
   
2. “Is this product 361 HCT/P compliant, or does it require FDA approval?”
   (If they can’t answer this clearly, walk away.)
   
3. “Has this tissue been cultured or expanded?”
   (If yes, it’s not legal in the U.S. unless part of an approved clinical trial.)
   

About the Treatment

4. “What does the research say about this treatment for my specific condition?”
   (They should reference studies, not just testimonials.)
   
5. “What are the potential risks and side effects?”
   (Every medical treatment has risks. If they say “none,” they’re not being honest.)
   
6. “How many treatments will I need, and what’s the total cost?”
   (Get the full financial picture before starting.)
   

About the Clinic

7. “Who will be performing the procedure?”
   (It should be a licensed physician or a supervised medical professional.)
   
8. “What happens if I don’t see results?”
   (Understand the follow-up plan and whether additional treatments are included.)
   
9. “Can you provide references or patient testimonials?”
   (Real clinics have real patients who are willing to share their experiences.)
