Fig. 3From: A novel kartogenin-platelet-rich plasma gel enhances chondrogenesis of bone marrow mesenchymal stem cells in vitro and promotes wounded meniscus healing in vivoStem cell marker expression in the BMSCs examined by immunostaining. a–c The cells were stained with nucleostemin. d–f The cells were stained with stro-1. g–i The cells were stained with CD44. j–l The cells were stained with CD90. a, d, g, j The cells were stained with H33342. b, e, h, k The cells were stained with the antibodies. c, f, i, l The images were merged images by a, d, g, j, and b, e, h, k. m The semi-quantification of positively stained cells by each stem cell marker. The insert images were enlarged box areas in the images of b and c. Bars 100 μmBack to article page
