Abstract (original English)
Aim The interaction between dental pulp stem cells (DPSCs) and vascular endothelial cells (ECs) is crucial to the speedy establishment of functional blood circulation within the transplanted pulp tissue. It is a complex process involving direct cell contact and paracrine signalling. The transmembrane domains of α1-Na + /K + -ATPase (ATP1A1) have been shown to influence tumour angiogenesis. Its role in regulating DPSCs/ECs interaction in vascular formation remains unknown. This study aimed to explore ATP1A1 on DPSCs/ECs communication, vascular network formation, and underlying mechanisms. Methods The formation of vessel structures within different culture systems was examined. The expression of pericyte-like markers and Na + /K + -ATPase-related genes and proteins were systematically analysed. Immunofluorescence staining was performed to examine the localisation of ATP1A1. Total and phosphorylated proteins were evaluated to identify and explore the signalling pathways activated under cocultured conditions. Downstream signalling was also investigated after the inhibition of ATP1A1. Results Direct coculture accelerated vessel network formation and prolonged its stability compared to indirect systems. ATP1A1 expression and SMC-specific marker (α-SMA) levels significantly increased in direct coculture systems, with nuclear α-SMA localisation and ATP1A1 enrichment at cell-contact sit
