ABSTRACT

BACKGROUND:

Researchers believe that hydrogen sulfide (H2S), as an important cell protective molecule, may become a new treatment method to restore the physiological function of diseased cells or organ systems through the artificial regulation of endogenous H2S biosynthesis or in vitro administration of H2S donor. ADT-OH is a slow-release donor of H2S that can improve the survival rate of hippocampal nerve cells with glutamate-induced injury, but studies on the proliferation of cerebral cortical neural precursor cells are rare.

OBJECTIVE:

To investigate the effect of ADT-OH on the proliferation of neural precursor cells in embryonic cerebral cortex.

METHODS:

Neural precursor cells from cerebral cortical ventricular zone and subventricular zone of embryonic mice at embryonic 14.5 days were isolated. Neural precursor cells from one fetal mouse were inoculated into one well (24-well plate), and cultured with the medium containing 100 μmol/L ADT-OH. The size and number of neural spheres per well were measured at 3 days after culture. The proliferation rate of cultured neural precursor cells was detected by BrdU labeling. The proliferation of the cells was further verified by immunofluorescence staining with the specific antibody Ki67. The expression of cyclin D1 was finally detected by western blot assay. RESULTS AND

CONCLUSION:

Our experimental results showed that ADT-OH could promote the formation of neural spheres, and further detection by BrdU and Ki67 antibody showed that ADT-OH could promote the proliferation rate of neural precursor cells. Meanwhile, the expression of cyclin D1, a proliferation-related gene, was up-regulated in neural precursor cells after ADT-OH treatment. Overall, ADT-OH may promote the proliferation of neural precursor cells by regulating the expression of cyclin D1.
