Cell cycle analysis of (A and B) gingival-derived mesenchymal stem cells (GMSCs) and (C and D) periodontal ligament stem cells (PDLSCs). (A and C) Representative cell cycle distribution of untreated GMSCs and PDLSCs. (B and D) Representative cell cycle distribution of GMSCs and PDLSCs co-cultured with apical tooth germ-conditioned medium (APTG-CM). APTG-CM-induced GMSCs and PDLSCs appeared to escape G₀/G₁ arrest and progressed to S and G₂/M phases.
