The main purpose of this in situ hybridization study was to investigate mRNA expression of three bone/cartilage matrix components (perlecan. DMP1. and MEPE) in developing primary (tibial) and secondary (condylar) cartilage. Perlecan mRNA expression was first detected in newly formed chondrocytes in tibial cartilage at E13. https://parisnaturalfoodes.shop/product-category/baking-cups-mini/
