Abstract

It has been proven that mesenchymal stromal cells (MSCs) can differentiate into tenocytes. Attempts to repair tendon lesions have been performed, mainly using scaffold carriers in experimental settings. In this article, we describe the clinical use of undifferentiated MSCs in racehorses. Significant clinical recovery was achieved in 9 of 11 horses evaluated using ultrasound analysis and their ability to return to racing. Our results show that the suspension of a small number of undifferentiated MSCs may be sufficient to repair damaged tendons without the use of scaffold support. Ultrasound scanning showed that fibers were correctly oriented. By using undifferentiated cells, no ectopic bone deposition occurred. A sufficient number of cells was recovered for therapeutic purposes in all but 1 case. We suggest that the use of autologous MSCs is a safe therapeutic method for treating incompletely (i.e., not full-thickness) damaged tendons. © 2007 Copyright 2007, Mary Ann Liebert, Inc.
