Figure 4

Treatment of meniscal defects (rabbit) in the avascular zone with a mesenchymal stem cell matrix composite resulted in defect filling with a differentiated meniscus like tissue compared to implantation of a cell free scaffold: Representative macroscopic views, histological (toluidine blue) and immunohistochemical (collagen type II) slides of menisci and the meniscal repair tissue 3 months after treatment of circular meniscal punch defects in the avascular zone; A, B, C: treatment with hyaluronan-collagen composite matrices loaded with mesenchymal stem cells; D, E, F: treatment with a cell-free composite matrix (control).
