Figure 1From: Thyroid hormones enhance the biomechanical functionality of scaffold-free neocartilage Phase 1 construct morphology and histological analysis. All constructs appeared smooth and hyaline-like. T3 and T4 treatments yielded smaller, thinner constructs, as compared to PTH and untreated controls (A). Collagen and GAG staining was uniform in all constructs (B). GAG, glycosaminoglycan; PTH, parathyroid hormone; T3, tri-iodothyronine; T4, thyroxine.Back to article page
