Introduction

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.
