Abstract Objective:To establish a mouse model that can trace the differentiation of CD133 positive neural stem cells.Methods:The CD133-Cre-ERT2 transgenic mice were mated with Rosa26-CAG-LSL-ZsGreen transgenic mice to produce CD133-CreER;CAG-ZsGreen double transgenic in C57B16 mice.Result:The immunohistochemistry and laser scanning confocal imaging analysis showed that Tamoxifen-Inducible Cre/loxP recombination, as depicted by green cells, existed in lateral ventricle SVZ, the ventricular zone of third ventricle and the fourth ventricle in adult mice, and the green fluorescence overlaps with CD133+ red fluorescence in these regions.Conclusion:CD133+ is the sign of the resting nerve stem cell in the ventricle membrane, so it can trace the cell differentiation lineages of neural stem cells by analyzing ZsGreen positive cells in CD133-CreER;CAG-ZsGreen mice. The mouse model for in vivo lineage tracing of endogenous CD133+ cell was established successfully, which will be helpful to explore the activation, proliferation, migration and differentiation of CD133+ neural stem cells in the brain.
