The overexpression of C/EBPβ promoted the proliferation of HPCs. ( A ) The diagram shows that cells were disassociated by TrypLE at HPC D7 and then seeded at 4 × 10 4 cells/cm 2 on collagen type I coated plates. Simultaneously, PLV-C/EBPβ virus was administrated. Subsequently, cells were disassociated again and counted at HPC D8 and HPC D14, respectively. ( B ) Cell numbers were determined by cell counts for HPC on day 8 and for HPC on day 14. ( C ) GSEA results showed that cell cycle and E2F targets related genes were significantly enriched in HPCs transduced with PLV-C/EBPβ on day 14 when compared with those transduced with PLV-Vector on day 14.
