Abstract:
Objective:To investigate the effects of ethylbenzene on growth morphology、proliferation ability and mitochondrial membrane potential (MMP) of cochlear progenitor cells (CPCs) , and to lay a foundation for the mechanism of hearing loss induced by ethylbenzene.
Methods:We can use the fluorescence microscopy to identify the original CPCs isolated from the newborn rats, and followed by the addition of different concentrations of ethylbenzene (0, 15, 30, 45 μmol/L) for 24 hours. The morphological changes of cell injury were observed by inverted optical microscope. The proliferation ability of cells was detected by MTT colorimetry, and the change of MMP was detected by fluorescent probe JC-1.
Results:The results of CPCs identification showed the expression of Myosin VIIa and Epsin positive; The results observed by inverted optical microscope showed all groups of CPCs morphological changes compared with the control group; MTT results showed that the decreased significantly proliferation ability of CPCs groups compared with the control group and a dose effect relationship with statistically significant difference (P<0.05) ; JC-1 test results showed the decreased significantly mitochondrial membrane potential in the treated group compared with the control group, and there was a statistically significant difference (P<0.05) .
Conclusion:Ethylbenzene may cause damage to CPCs, inhibition of cell proliferation and decrease of MMP in rats.
