CD24+ NP cells exhibit a higher proliferation rate and higher osteogenic/adipogenic/chondrogenic differentiation ability than CD24− and unsorted NP cells in vitro. a The proliferative activity of CD24+, CD24− and unsorted NP cells detected by CCK8. b-c Osteogenic differentiation of CD24+, CD24− and unsorted NP cells analysed by alkaline phosphatase (b) and alizarin red staining (c). d Adipogenic differentiation of CD24+, CD24− and unsorted NP cells analysed by oil red O staining. e Chondrogenic differentiation of CD24+, CD24− and unsorted NP cells analysed by alcian blue staining. **P < 0.01, ***P < 0.001. P-values were analyzed by one-way ANOVA
