The results showed:(1) the cellule morphous and the disposition in chick embryo of PGCs were coincident no matter stained by PAS or HE staining, and HE staining could disclose the morphologic characteristics more clearly, exactly and completely;(2) genesis of blood island could be observed at the boundary of light and dark region of the extraembryonic blastoderm at about 26 hours;(3) both the blood vessel endothelium cells and free cells of the blood island were differentiated from PGCs. The generating of genuine yolk sac was at about 44-48 hours.

结果表明:①用经典的识别原生殖细胞的PAS染色方法与HE染色所观察到的PGC在鸡胚的分布及细胞形态基本一致,而HE染色较PAS法能更有助于清晰、完整、准确地识别PGC的细胞内部结构特征;②在孵化26小时的鸡胚胚外胚盘的明暗交界处可见血岛的发生,血岛发生的时间比真正的卵黄囊产生时间(大约44-48小时)要早很多;③血岛周围的血管内皮细胞与管腔中游离细胞都来自PGC。

Under the optimized conditions, the relative fluorescence intensity decreased linearly with the copper ions concentration in the range from 2 to 200μg·L~(-1) and the detection limit could reach 0.29μg·L~(-1). Based on the charge-transfer quenching mechanism, the copper ions bounding onto the surface of qdots could absorb electrons from valance band, which results in the quenching of fluorescence.
