IHDPCs acquired strong self-renewal and proliferation ability. (a) Cell proliferation was observed by the CCK8 assay (, ). (b) Colony formation assay using crystal violet staining. (c) Cell proliferation assessed by the crystal violet staining assay. (d) The stain extracted from the cells was dissolved for quantitative determination at A570 nm (, ).
