Increased expression of chondrogenic markers will be Evaluated by different techniques:

in vitro: Histology fit for chondrogenic markers, RT-PCR on the following markers aggrecan, type II collagen, Sox9, Comp, type IX collagen

in vivo: In a second step, differentiated MSCs are implanted in vivo after combination with a hydrogel subcutaneously in nude mice. The formation of a neo cartilage tissue will be assessed by histology for type II collagen and aggrecan
