Chondrogenic differentiation of MenSCs and BMMSCs stimulated with activin A (50 ng/mL), TGF-β3 (10 ng/mL), and both activin A and TGF-β3, where activin A was added only during first 2 days. Histological analysis of cell pellets (Safranin O staining after 21 days of chondrogenic stimulation). Control cells were cultivated in chondrogenic medium without growth factors. Scale bars 100 μm and 500 μm
