Left: Osteochondral constructs with porous tantalum metal as a substrate (OC(tantalum)) compared to a trabecular bone substrate (OC(bone)) or no substrate(Gel). *p < 0.05 vs. previous time point. +p < 0.05 vs. Gel. §p < 0.05 °C(bone) vs. OC(tantalum). n = 12 per group. Right: Images of developing osteochondral constructs showing more robust growth for tantalum substrate over bone, OC(bone) on day 14 (B14) and day 42 (B42), OC(tantalum) on day 14 (T14) and day 42 (T42). Histological staining for GAG (alcian blue staining, dark purple) on day 42 for Gel, OC(tantalum), and OC(bone). Deeper intensity of purple indicates the presence of more GAG. Some shrinkage occurred in processing. Scale bar = 1 mm.
