Evidence-Based Regenerative Medicine
The Science Behind Your Treatment
Every Colombia Care protocol is informed by published clinical research, INVIMA-regulated methodology, and certified cell science. Here's how mesenchymal stem cells are thought to work, what the studies show so far, and where the evidence is still limited.
Research & Regulatory Partners
01 — The Science
What are mesenchymal stem cells?
Mesenchymal stem cells (MSCs) are multipotent adult cells found in umbilical cord tissue, bone marrow, and adipose tissue. Unlike embryonic stem cells, MSCs are ethically sourced and carry no controversial associations. They're among the most widely studied cells in regenerative medicine.
Researchers are studying four properties of MSCs as potential therapeutic tools:
- Differentiation — MSCs can develop into bone, cartilage, muscle, tendon, and fat cells in the laboratory; how much this happens after injection in people is less clear
- Paracrine signaling — They release growth factors, cytokines, and exosomes that may help signal the body's own repair processes
- Immunomodulation — MSCs can modulate immune responses and may help calm inflammation linked to chronic pain and tissue degeneration
- Anti-fibrotic effects — In preclinical studies they reduce scar tissue formation, which may support more functional tissue repair
In simple terms: the aim is to support the body's own repair processes, not just mask symptoms. Clinical results so far are promising but mixed: in trials, some patients report less pain and better function and others don't, and MSC therapy has not been shown to regrow cartilage or reverse arthritis.
02 — Regulation
INVIMA: Colombia's FDA equivalent.
INVIMA (Instituto Nacional de Vigilancia de Medicamentos y Alimentos) is Colombia's national regulatory authority for medicines, medical devices, and biological products. It functions like the US FDA or Europe's EMA — overseeing clinical standards, facility inspections, and product safety across the country.
INVIMA regulates every aspect of our practice: the stem cell products we use, the laboratory that processes them, the facilities where treatments are administered, and the clinical protocols our physicians follow. Non-compliance carries severe penalties, including facility closure.
- Government oversight of all biological products and medical procedures
- Facility inspections and licensing requirements
- Same regulatory framework as Colombia's hospitals and pharmaceutical industry
- Your treatment is a medical procedure under enforced clinical standards — not a wellness experiment
03 — Our Laboratory
Innocell: GMP-certified cell processing.
Colombia Care partners exclusively with Innocell — a GMP-certified stem cell laboratory in Colombia. Innocell operates under GMP (Good Manufacturing Practice) certification, the international gold standard for pharmaceutical and biological product manufacturing.
Every batch of mesenchymal stem cells used in our protocols is processed, tested, and documented by Innocell's team of cell biologists. This is a clinical partnership that ensures consistency, traceability, and quality at every step.
- GMP-certified processing facility
- Cell viability testing on every batch (minimum 95% viability threshold)
- Sterility and endotoxin testing per international standards

- Ethically sourced umbilical cord tissue (Wharton's jelly)
- Screened, healthy donors from full-term pregnancies
Published research supporting MSC therapy.
Below are peer-reviewed studies and meta-analyses relevant to the protocols we offer. Links open directly on PubMed / NIH.
01
Orthopedic & Joint Conditions
Small randomized trials and meta-analyses report improvements in pain and function after MSC injections for knee osteoarthritis, and one phase II trial compared favourably with hyaluronic acid at 12 months. Trials are small, results are mixed, and evidence that cartilage is actually rebuilt remains limited.

02
Spinal & Disc Conditions
Early trials of intradiscal cell injections have reported pain relief lasting 24+ months in some patients with degenerative disc disease. Results have been mixed, evidence that disc height or structure is restored remains limited, and larger trials are still needed.

03
Chronic Pain & Inflammation
MSCs have well-documented immunomodulatory effects in laboratory studies. For chronic pain conditions such as neuropathic pain, clinical evidence is still early and limited; injectable biologics are being studied as an option when conventional treatments have not helped.

04
Aesthetic & Hair Restoration
Laboratory and early clinical studies suggest MSC-derived growth factors and exosomes may support collagen production and skin quality. For pattern hair loss, a small randomized trial of a stem cell extract reported increased hair density; larger studies are needed and results vary.

05
IV & Systemic Therapy
IV-administered MSC therapy has been studied in research settings for systemic inflammation and a range of conditions, including autoimmune disease. Pooled trial data support its safety profile so far; evidence of benefit is still early, and we do not offer it as a treatment for autoimmune conditions.

From consultation to recovery — every step is evidence-informed.
Our treatment methodology follows a structured, physician-led process designed to give you the best chance of benefit while keeping risk as low as possible. Results vary, and not everyone responds.
01
Clinical Assessment & Imaging Review
Your protocol begins with a comprehensive evaluation: medical history review, imaging analysis (MRI, X-ray, ultrasound), and a virtual consultation with your assigned specialist. We determine whether MSC therapy is appropriate for your specific condition and establish measurable treatment goals.
02
Cell Selection & Preparation
Based on your condition, our physician prescribes the optimal cell type, dosage, and delivery method. Innocell prepares your MSC batch — viability tested, sterility confirmed, and documented with full chain-of-custody traceability. Cells are delivered fresh to our clinic on the day of your procedure.
03
Image-Guided Administration
For orthopedic and spinal protocols, MSCs are delivered via ultrasound or fluoroscopy-guided injection — ensuring precise placement at the injury site. IV protocols use controlled infusion with real-time monitoring. Aesthetic protocols use targeted intradermal or subcutaneous injection techniques. Precise placement helps the cells reach the intended area.
04
Post-Treatment Monitoring
Immediately after treatment, you're monitored at our clinic. Your physician provides personalized recovery guidelines: activity restrictions, anti-inflammatory management, and what to expect over the following weeks and months. Most patients can resume normal activities within 24–72 hours depending on the protocol.
05
Telemedicine Follow-Up
Your care continues after you leave Medellín. Scheduled telemedicine consultations at 2 weeks, 6 weeks, 3 months, and 6 months post-treatment allow us to track your progress, answer questions, and adjust your rehabilitation plan. You're never alone in your recovery.
06 — Safety & Quality
Your safety is non-negotiable.
Regenerative medicine demands rigorous standards at every stage. All MSCs are sourced from ethically obtained umbilical cord tissue from screened, healthy donors — tested for sterility, endotoxins, mycoplasma, and viability before release. Innocell's GMP-certified lab operates in ISO Class 7 clean rooms with full batch-level documentation.
Every treatment is prescribed and administered by a licensed physician using image-guided delivery. Post-procedure monitoring and telemedicine follow-ups help catch any adverse events early. Common side effects are mild and transient — localized swelling, minor bruising, and temporary discomfort.
- Donor screening: HIV, Hepatitis B & C, syphilis, CMV
- Cell batch testing: sterility, endotoxins, mycoplasma, viability (≥95%)
- ISO Class 7 clean room & GMP-certified processing
- Licensed physicians with regenerative medicine training
- Active screening for contraindications (cancer, uncontrolled infection, pregnancy)
- Honest assessments — we decline patients who aren't good candidates
Questions about the science.
What are mesenchymal stem cells (MSCs)?
Mesenchymal stem cells are multipotent adult cells that can develop into bone, cartilage, muscle, and fat cells in the laboratory. They also release growth factors and anti-inflammatory signals that, in laboratory and early clinical studies, appear to support the body's own repair processes. Colombia Care uses MSCs sourced from ethically obtained umbilical cord tissue, processed in a GMP-certified laboratory.
Where do the stem cells come from?
Our MSCs are sourced from umbilical cord tissue (Wharton's jelly) — collected from healthy, screened donors after full-term pregnancies. This is one of the richest sources of young, potent mesenchymal stem cells. The tissue is ethically obtained with informed consent and would otherwise be discarded as medical waste.
Is stem cell therapy safe?
In published clinical trials so far, MSC therapy has shown a favourable safety profile, though long-term data are still limited and no procedure is risk-free. Common side effects are usually mild and temporary: localized swelling, minor bruising, and discomfort at the injection site. Serious adverse events appear to be uncommon in published studies. INVIMA regulation, GMP-certified cell processing, and physician-led protocols are designed to reduce risk, but cannot remove it entirely.
Is stem cell therapy legal in Colombia?
Yes. Colombia has a regulatory framework for regenerative medicine under INVIMA (Colombia's FDA equivalent). Unlike many countries that have not yet established clear regulatory pathways for stem cell therapy, Colombia provides a legal, regulated environment for MSC treatments — which is one of the reasons international patients choose Medellín for regenerative medicine.
How does Colombia's regulatory framework compare to the US?
In the US, the FDA classifies most stem cell therapies as investigational, meaning they're typically only available through clinical trials. Colombia's INVIMA permits MSC therapy under regulatory oversight — similar to how other countries like Japan, South Korea, and parts of the EU have established expedited regulatory pathways for regenerative therapies. This means you can access treatments in Colombia that may not yet be available through standard US medical channels.
What is GMP certification and why does it matter?
GMP (Good Manufacturing Practice) is the international standard for pharmaceutical and biological product manufacturing. Innocell's GMP certification means their cell processing follows validated protocols, uses calibrated equipment in clean-room environments, and maintains rigorous documentation. It's the same standard applied to drug manufacturing worldwide.
How many stem cells are used per treatment?
Cell dosage varies by condition, delivery method, and treatment goals. Typical protocols range from 20 million to 100+ million MSCs depending on whether the treatment is localized (joint injection) or systemic (IV infusion). Your physician determines the optimal dosage based on your clinical assessment and published dosing evidence.
How long do results last?
Results vary by condition and patient, and not everyone responds. Some published studies on orthopedic MSC therapy report improvements lasting 12–24+ months in patients who respond; others show smaller or shorter-lived effects. Some patients opt for maintenance protocols annually. During your consultation, your physician will provide evidence-based expectations specific to your condition.
