Figure 1From: Extracellular matrix production in vitro in cartilage tissue engineering Evaluation of GAGs, Col2a1 and aggrecan in passaged rabbit chondrocytes. (A-C) Toluidine blue staining showed production of GAGs from cells declined following passaging from P0 (A), P1 (B) to P2 (C). Scale bar: 100 μm. (D-E) Real time PCR showed the expression of Col2a1 (D) and aggrecan (E) decreased with cell passaging.Back to article page
