However, compared to control cells, adipocytes differentiation from OM and IPFP fat sources tended to show a higher expression of FABP4 and PPARγ. When MSCs were differentiated to osteogenic lineage, they were evaluated for osteogenic markers (SP7, osteocalcin, and osteopontin) as shown in Fig. 7G-I. This evidence concerns the gene PPARG and ocular melanoma.
