WebCytoplasmic asters were localized by staining with an anti-a-tubulin antibody. Enucle-ation of MII oocytes caused no significant change in the number of cytoplasmic asters. WebMar 15, 2012 · In the next experiment, multiple asters observed in 5.5 vs 8 hpi pronuclear zygotes were located near the male pronucleus, suggesting that those multiple asters were not the cytoplasmic asters of maternal origin.

WebFeb 16, 1999 · Thus, the sperm centrosome must have recruited γ-tubulin from the maternal cytoplasm and gained the ability to nucleate Mts and form asters after entry into the oocyte. Surprisingly, 20 min after fertilization, during metaphase of meiosis I, neither sperm asters nor γ-tubulin staining was found associated with sperm nuclei (Fig. 1 C ). WebThe cytoplasmic foci were larger and more abundant than in untreated oocytes (Table 1). Double staining revealed that the anti-γ- tubulin reactivity was found in the center of all the asters...
