Figure 3. Detection of Prx II+/+ DMSC and Prx II−/− DMSC proliferation and stem cell stem-related proteins. (A) Cell proliferation was detected by performing MTT assays after culturing for 24 h. (B, C) Western blot analysis of Prx II+/+ DMSC and Prx II−/− DMSC extracts, and data quantification, in order to investigate stem cell stem-related proteins, such as Nanog, KLF4, and c-Myc.
