It is well-known that extracellular ATP acts as an autocrine/paracrine signal to regulate cell functions by inducing intracellular Ca2+ signalling through its cognate receptors, namely, the ligand-gated ion channel P2X receptors that mediate Ca2+ influx and/or the Gq/11-coupled P2Y receptors that link to Ca2+ release from the ER. The reduction in ER Ca2+ can trigger further extracellular Ca2+ entry by activating the store-operated Ca2+ (SOC) channel. Mesenchymal stem cells (MSC) play an important role in the homeostasis of residing tissues and have promising applications in regenerative medicines. MSC can release ATP spontaneously or in response to diverse stimuli, and express multiple P2X and Gq/11-coupled P2Y receptors that participate in ATP-induced Ca2+ signalling and regulate cell function. There is increasing evidence to show the contribution of the SOC channel in ATP-induced Ca2+ signalling in MSC. In this mini-review, we discuss the current understanding of the expression of the SOC channel in MSC and its potential role in mediating ATP-induced Ca2+ signalling and regulation of MSC differentiation, proliferation and migration.
