Abstract
Mesenchymal stem cells (MSC) are capable of multilineage differentiation into cells like osteoblasts, chondrocytes or adipocytes. MSCs can be isolated from bone marrow and expanded ex vivo for up to 25-40 population doublings while maintaining genetic stability and differentiation potential. MSCs ha...

Abstract
Mean T2 values (ms) were comparable for the control cartilage (53.4 +/- 11.7) and the repair tissue (55.5 +/- 11.6) (p > 0.05). Mean T2* values (ms) for control cartilage (30.9 +/- 6.6) were significantly higher than those of the repair tissue (24.5 +/- 8.1) (p < 0.001). Zonal stratification was mor...

Although we cannot establish a causal link, the development of glenohumeral chondrolysis may be related to the intra-articular infusion of bupivacaine with epinephrine postoperatively. We thus caution against the use of IAPPCs. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
