Abstract:
AIM:To observe the functional expression of calcium-sensing receptor (CaSR) in the mouse em-bryonic stem cells (mESCs).METHODS:The expression and distribution of CaSR were detected by Western blotting and immunofluorescence observation in 129 mouse ES-D3 cells.The intracellular concentration of free calcium ([Ca2+]i) was determined by confocal laser scanning microscopy .The cell viability was analyzed by MTT assay and flow cytometry .RE-SULTS:CaSR protein was expressed in mESCs .Extracellular calcium or neomycin significantly increased the expression of CaSR and [Ca2+]i.Neomycin increased the cell viability , up-regulated the protein expression of p-ERK2.These effects of neomycin were inhibited by NPS2390.CONCLUSION:CaSR is expressed in mESCs .The activation of CaSR is involved in the proliferation of mESCs .
