Figure 7. Comparison of expression of potential key genes and Apoptosis test in chondrocytes.
(A. MAPK-14; B. PTPRC; C. PTPN12; D. B9D1). All samples were normalized to the expression of GAPDH, and the relative expression levels of each gene were analyzed using the 2ΔΔCT method. (E–J) Apoptosis test of chondrocytes (DIC, bright field imaging; PI, Propidium iodide staining imaging; Merged, composite imaging). The red arrow refers to cells that are stained or not by PI.
