Regenerating Your Pet

Veterinary Stem Cells Manufactured In South Africa

Veterinary Stem cell treatment in South Africa is an evolving field offering alternatives to surgery or long-term medication. It is used mainly as a “regenerative therapy” to help dogs, cats and horses recover from injuries or minimise clinical signs related to degenerative conditions such as:

However not all animals or diseases can be treated. Its use in cancer is contraindicated. Stem cell therapy is a veterinary procedure, and therefore stem cells can only be sold to veterinarians registered with the South African Veterinary Council.

Innovative Technology

About Us

VetRenew is a leading provider of cutting-edge regenerative therapies tailored for the South African veterinary community. We specialise in the supply of allogeneic mesenchymal stem cells (aMSCs) derived from adipose tissue—offering a powerful, science-based solution for degenerative conditions such as Osteoarthritis, keraconjunctivitis sicca (Dry Eye) Feline Chronic Kidney Disease (CKD) and more.

Our aMSCs are widely recognised in research and clinical applications for their ability to proliferate into multipotent cells, aiding in tissue repair and regeneration. Each donor undergoes comprehensive screening, including a clinical examination, blood smear, complete blood count and serum biochemistry, and in cats viral testing done. Once harvested, the cells are cultured and carefully passaged, with ongoing sterility checks and flow cytometry to confirm key cell surface markers such as high CD90 expression and the absence of MHII.

At VetRenew, we are committed to innovation, safety, and advancing veterinary care through scientifically validated stem cell therapies.
