Native meniscal biochemical composition and tissue structure are maintained after both decellularization and sterilization. A Hydroxyproline content. B-D Histological sections of native (B), decellularized (C), and decellularized + sterilized meniscus (C) were stained with Picro Sirius Red. E Glycosaminoglycan content. F-H Histological sections of native (F), decellularized (G), and decellularized + sterilized meniscus (H) were stained with Alcian Blue. Box plots show all data points with median, maximum value, minimum value, and 25th and 75th percentiles. Scale bar represents 100 μm
