Cellular Proliferation Of Equine Bone Marrow- And Adipose Tissue-Derived Mesenchymal Stem Cells Decline With Increasing Donor Age, Jasmin Bagge, James N. Macleod, Lise C. Berg

Maxwell H. Gluck Equine Research Center Faculty Publications

Background: Bone marrow (BM)- and adipose tissue (AT)-derived mesenchymal stem cells (MSCs) are used increasingly for autologous cell therapy in equine practice to treat musculoskeletal and other injuries. Current recommendations often call for 10–100 million MSCs per treatment, necessitating the expansion of primary cells in culture prior to therapeutic use. Of concern, human and rodent studies have shown a decline of both MSC recovery from sampled tissue and in vitro proliferative capacity with increasing donor age. This may be problematic for applications of autologous cell-based therapies in the important equine demographic of older patients.
