ABSTRACT
Objective To measure the concentration of intracellular free Ca2+ ([Ca2+]i) in neuron-like cells resulted from rat bone mesenchymal stem cell (BMSCs) differentiation induced by salvia miltiorrhiza injection and provide some theoretical basis for the BMSCs transplantation. Methods The rat BMSCs were separated from rat bone marrow and cultured in vitro. After induced by basic fibroblast growth factor and 10mL/L salvia miltiorrhiza injection, the cells were identified with immunofluorescence staining against NeuN. The same procedure was performed on primarily cultured hippocampal neurons. Then, the [Ca2+]i of the differentiated neuron-like cells was determined and compared with primarily cultured hippocampal neurons. Results The BMSCs after induced by basic fibroblast growth factor and salvia miltiorrhiza injection expressed neuronal phenotypes similar to the cell appearance of neurons with NeuN. The average fluorescence intensity of the neuron-like cells derived from BMSCs was 984.75±79.51, while the average fluorescence intensity of the primarily cultured hippocampal neurons was 769.42±60.93. No significant difference was found between them (P>0.05). Conclusion The neuron-like cells from rat BMSCs differentiation induced by salvia miltiorrhiza injection possess certain neuronal properties.
