Plain-English summary

A dog with a joint injury that caused an osteochondral defect (a type of cartilage damage) received a treatment involving a special gel containing its own bone marrow-derived stem cells. While the cartilage didn't show signs of early healing, the underlying bone began to regenerate significantly within two weeks. The stem cells appeared to move deeper into the defect, likely due to increased pressure from inflammation after the surgery. This suggests that using stem cells could help with bone repair in similar cases, even if cartilage healing takes longer.

Abstract

To clarify the contribution of autologous transplantation of mesenchymal stromal cells (MSCs), an atelocollagen gel containing or not containing fluorescently-labeled canine MSCs was transplanted into an osteochondral defect which did not repair spontaneously and the histological repair of the defect was compared. Although an early repair of the cartilage was not observed in either defect, the reproduction of subchondral bone was remarkable in the MSCs-implanted defect. Moreover, in 2 weeks after operation, the implanted MSCs were located in the deeper regions of the defect, suggesting the differentiation of osteoblasts. There was a possibility that the movement of the implanted MSCs was due to an increase in intra-articular pressure from postoperative inflammation.
