Clonogenicity and self- renewal ability of stromal FPC and non-FPC post-labeled day 15 and 21. (A – D) Cloning efficiency of endometrial stromal cells post-labeled with nanoparticles at day 15 (white bars) and 21 (grey bars). Cloning efficiency of large CFU (A) FPC and (B) non-FPC. Cloning efficiency of small CFU (C) FPC and (D) non-FPC. (E – H) Self-renewal activity of endometrial stromal cells post-labeled with nanoparticles at day 15 (white bars) and 21 (grey bars) using serial cloning assay. Large CFU self-renewal ability of (E) FPC and (F) non-FPC. Small CFU self-renewal ability of (G) FPC and (H) non-FPC Results reported as means ± SEM, n = 4, *^{, a, b}P <0.05. CFU, colony-forming units; FPC, fluorescent persistent cells; SEM, standard error of the mean.
