WebNSN oocytes showed a significantly lower GVBD rate ( Figure 2G) and 1st polar body extrusion rate (Figure 2H) than SN oocytes. Web11 feb. 2014 · ELAVL2° is abundant in fully grown NSN oocytes, is ablated during the NSN/SN transition and remains low during the oocyte-to-embryo transition (OET). ELAVL2° overexpression during meiotic maturation causes errors in chromosome segregation, indicating the significance of naturally reduced ELAVL2° levels in SN oocytes.
