Abstract EN
Porcine bone marrow mesenchymal stem cells (pBMSCs) have the potential for application in regenerative medicine.
This study aims to investigate the effects of extracellular calcium ( C a 2 + o ) on pBMSCs proliferation and to explore the possible underlying mechanisms.
The results demonstrated that 4 mM C a 2 + o significantly promoted pBMSCs proliferation by reducing the G0/G1 phase cell percentage and by increasing the S phase cell proportion and the proliferation index of pBMSCs.
Accordingly, C a 2 + o stimulated the expression levels of proliferative genes such as cyclin A2, cyclin D1/3, cyclin E2, and PCNA and inhibited the expression of p21.
In addition, C a 2 + o resulted in a significant elevation of intracellular calcium and an increased ratio of p-ERK/ERK.
However, inhibition of calcium-sensing receptor (CaSR) by its antagonist NPS2143 abolished the aforementioned effects of C a 2 + o .
Moreover, C a 2 + o -induced promotion of pBMSCs proliferation, the changes of proliferative genes expression levels, and the activation of ERK1/2 signaling pathway were effectively blocked by U0126, a selective ERK kinase inhibitor.
In conclusion, our findings provided evidence that the enhanced pBMSCs proliferation in response to C a 2 + o was associated with the activation of CaSR and ERK1/2 signaling pathway, which may be useful for the application of pBMSCs in future clinical studies aimed at tissue regeneration and repair.
