Transportation media and injection protocol have implications for the viability of MSCs used for intra-lesional treatment of tendon injuries. Every effort should be made to implant cells within 24h of laboratory re-suspension, using a needle bore larger than 21G. Intra-lesional implantation of autologous mesenchymal stem cells (MSCs) has resulted in significant improvements in tendon healing in experimental animal models. Intra-tendinous injection of MSCs into naturally-occurring equine tendon injuries has been shown to be both safe and efficacious1 and these protocols can assist in the translation to the human. Efficient transfer of cells from the laboratory into the tissue requires well validated techniques for transportation and implantation. The aim of this study was to determine the influence of transport media and injection procedure on cellular damage.Summary Statement
