Cells stained with Safranin O. Cells cultured in chondrogenic medium (a)–(d), activated PRC (e)–(h), and nonactivated PRC (i)–(l). Cells cultured in PRC were fixed with formalin after each time point and were stained with Safranin O. Cells cultured in chondrogenic medium served as the positive control.
