The spheres were washed twice and stained with 1:500 PI solution (Bio-Sciences) supplemented with 250 g/mL RNAse A (Qiagen) and Hoechst nuclear counterstain (2 g/mL) (Bio-Sciences) for 30 min protected from light, at room temperature
Zonal organization: Articular cartilage has superficial zone (tangential collagen orientation, highest cell density), middle zone (random collagen orientation, largest proteoglycans), deep zone (perpendicular collagen orientation, calcified interface with bone), and tidemark (boundary between calcified and uncalcified cartilage)
Important: All cited research reflects preclinical findings from animal and cell studies
