Figure 10From: Homing and reparative effect of intra-articular injection of autologus mesenchymal stem cells in osteoarthritic animal model Fluorescence microscopic analysis of the cell-treated joints showing GFP-positive cells detected at the surface and also in the center of regenerated tissue in all groups. Group-I; (a) at 2 months and (b) at 6 month after injection of GFP-transduced MSCs. Group-II; show diffuse hypercellularity after 2 months (c) and clusters of chondrocytes after 6 months of injection (d). Group-III; show slight hypercellularity after 2 month (e) with clusters of chondrocytes (short arrow) and multiple tide marks (long arrow) after 6 months of injection (f).Back to article page
