Mammlian oocytes: from fully grown to first cell division

Illustrates the earliest process of life in mammals. A fully grown oocyte matures into an ovulating oocyte, and upon fertilization, it cleaves into a 2-cell embryo. These samples were collected from Mus Musculus B6D2F1.本数据集呈现了哺乳动物生命早期的起始发育进程。完全成熟的卵母细胞（oocyte）可进一步成熟为排卵卵母细胞，受精后经卵裂形成2-cell embryo。本次实验的样本采集自小家鼠（Mus Musculus）B6D2F1品系。
