Abstract:
To investigate the role of Ash2l (absent, small, or homeotic 2-like, Ash2l) on the proliferation ability and cell cycle of mouse cerebral cortical neural progenitor cells (NPCs), We examined the number and distribution of NPCs, using the radial glial cell marker PAX6 and intermediate progenitor cell marker TBR2. E16. 5 mice were labeled with EdU for 30 min to detect the proliferation ability of NPCs. Conditional knockout of Ash2l resulted in a dramatic reduction in the number of NPCs and a disordered distribution. The 30 min EdU insertion experiment showed that EdU could hardly be inserted into NPCs, indicating that the proliferation ability of NPCs was severely affected. Using the mitotic cell cycle marker pH3, the distribution of dividing NPCs was observed. We then detected the expressed level of Cyclin A by Western blotting. The distribution of cell nuclei of M-phase is disordered and the expression of G
