FIG. 4.

Western blot analyses showing differentiation markers of adipogenic, chondrogenic, and osteogenic lineages. The expression of specific proteins for each lineage were analyzed in differentiated cells as well as in cells not differentiated and in protein samples derived from fat, cartilage, and bone as positive controls. (A) Adipogenic lineage, adiponectin and resistin. (B) Chondrogenic lineage, elastin and aggrecan. (C) Osteogenic lineage, bone alkaline phosphatase and RUNX2. M represents the marker lane.
