Actor Abhay Deol recently opened up about his long-standing battle with knee pain and sciatica, sharing his experience with stem cell treatment. He said the procedure felt remarkably natural, as it used his own cells rather than synthetic materials to aid healing. Reflecting on the experience, the actor described it as a sign of how far medical science has progressed, adding that it felt like his body was repairing itself.

His post has once again brought attention to stem cell therapy, a treatment approach that uses living cells to repair damaged tissue, relieve pain and potentially slow certain degenerative processes. While interest in these therapies is steadily rising and more clinics are offering them, medical experts warn that not all stem cell treatments are backed by the same level of scientific evidence or safety standards.

The promise of stem cells is undeniable. These tiny living units hold the potential to repair damaged tissue, ease chronic pain and even slow the ageing process. Yet, as the market for regenerative medicine grows, so too does the risk of patients falling prey to clinics that sell hope without science.

Across the world, clinics are advertising stem cell therapy as a fast, permanent solution for a long list of health issues. From joint pain to neurological disorders, the stem cells are said to fix almost anything. Dr Pradeep Mahajan, Regenerative Medicine Researcher & Founder, Dr Mahajan's Hospital & Industrial Trauma Centre, Navi Mumbai, says, “But the reality is far more complex. Unlike regulated medical treatments, many commercially marketed stem cell procedures operate in a grey zone, where safety rules and scientific protocols are often ignored.”

The danger is not just in the promise, but in the practice. “Stem cells are living entities—sensitive, unpredictable and demanding. When clinics bypass quality control, there is no guarantee that the cells used are the right type, properly screened or even safe.” He says and adds, “Contaminated or incorrectly handled cells can lead to infections, allergic reactions, immune problems, or irreversible tissue damages

Dr Mahajan shares 5 risks of unregulated stem cell procedures

Safety standards are often ignored

“In the race to sell treatments, many clinics cut corners on testing and screening,” says Dr Mahajan informs. “Stem cell therapy must be done with science, not sales.”

Misleading advertising fuels false hope

Certain clinics often claim stem cells can cure almost anything, without explaining limitations or the need for thorough medical assessment. Patients may delay proper treatment, allowing conditions to worsen.

Injections require advanced skill

Injecting stem cells into joints, muscles or the spine is a complex procedure. Poor technique can cause nerve injury, inflammation, infection, or lasting harm. Unregulated clinics often lack trained specialists and adequate follow-up care.

Living cells are extremely sensitive

“Cells are living, breathing entities like us,” Dr Mahajan explains. “They need ideal conditions, temperature, air quality, humidity and careful handling, to survive and function.” A minor lapse in storage or transport can ruin the therapy.

You may be paying for the wrong product

As the field grows, products such as exosomes, growth factors, platelets and extracellular matrix molecules are becoming popular. But many clinics still offer unproven or low-quality treatments under the guise of “stem cell therapy.”

Stem cell treatment can be life-changing—but only when it is delivered by qualified specialists in controlled medical settings. Patients should ask questions, verify credentials and be wary of clinics promising miracle cures. Dr Mahajan warns, “the future of regenerative medicine should be guided by science, not marketing”

FAQs on Stem Cell Hype vs Reality

1. Are stem cells as effective as advertised?

Stem cells have great potential, but their effectiveness varies. Many claims made by clinics lack solid scientific backing.

2. What should I be cautious of when considering stem cell therapy?

Be wary of clinics that promise quick, miracle cures. Ensure they follow strict safety standards and have qualified professionals.
