Dr. Nassim Abi Chahine

About the Founder

Nassim Abi Chahine is a Lebanese neurosurgeon, European board holder with a Polish medical doctorate since 2002. In 2008, at age of 31, he was the first in his region to start research, development, and application of bone marrow autografts for regeneration.

Nassim Abi Chahine created a wide series of stem cell therapeutic protocols, just before being forced by the local syndicate in 2012 to stop his therapy for many months. Soon after that, ministry permission was granted and he then received an exceptional government clearance and support to continue his research.

In 2014, he finalized his Regentime® procedure based on the transplantation of proliferated partially differentiated and specifically redirected autologous bone marrow derived mononuclear progenitor stem cells, registering it in 2015 with a trademark ID number 168469 as an intellectual property at the Lebanese ministry of economy.

The founder successfully treated non-responsive to conventional medicine hopeless cases, pioneering the field of regeneration in the Middle East and Neuroregeneration worldwide. He launched his procedure at the BIT's 8th World Congress of Regenerative Medicine & Stem in Shanghai, China in 2015

Dr. Nassim's work has broadened internationally with such success and is growing. Based in Lebanon, he travels continuously for further development adding innovations and modifications for the most accurate results.

At the professional level, he is a genuine and approachable physician, allowing easy communication methods for questions regarding the use of Regentime® treatments for patient satisfaction and peace of mind.


Regentime points the regeneration with the time as a golden factor of success. "The sooner the better" or "fast act is the key of success".


The figure ∞ means the infinite, thus the symbol “∞” indicates the great potential of medicine, the extent of the new regenerative medicine field.

Our Procedures
This procedure is used for patients who experience neck pain or low back pain from degeneration of the discs in the vertebrae or joint pain as a result of osteoarthritis in the knees, hips, or shoulders.
Amniotic membrane therapy is another type of regenerative medicine used in the treatment of chronic pain.
The procedure requires an injection of autologous growth factors, secretory proteins, and concentrated platelets.
Transplantation of natural tissues is not always possible due to lack of availability of natural organ or tissue. In such cases, artificial tissue analogues such as blood substitutes, artificial aortic valves, or bone-like polymeric composites are used as substitutes.
Cell replacement therapy offers great promise as the future of regenerative medicine.
Organ transplantation is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ.

Regenerative medicine is a technique to replace or repair defective or diseased tissue or organs by in vitro design with in vivo usage. It can be considered a relatively new branch of medicine born in 1997 when Whithman DH et al. proposed to integrate platelet enriched plasma (PRP) in fibrin glue. In 1998 Marx et al. demonstrated that PRP was able to induce bone regeneration of the jaw. In the same period it was discovered that a fraction of stem cells of bone marrow origin was able to repair several mesenchymal tissues or organs.
