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。

In the first part of the study, it was demonstrated that there was only 0.1% of PCV2 antigen-containing rate in PBL isolated from PCV2-free pigs and treated simultaneously with mitogen and PCV2. The results of both MTT assay and blastogenesis indicated that PCV2 could reduce the responsiveness of PBL to mitogen stimulation, but the results of survival and apoptotic rates indicated that PCV2 had no effects on the viability of PBL.

首先，在第一阶段实验中针对健康无PCV2带原的猪只进行测试，当同时对其PBL以致裂原刺激与PCV2攻毒处理后，其PBL中仅0.1％的细胞呈现PCV2抗原阳性；藉由MTT与blastogenesis分析，均显示PCV2可以降低PBL对於致裂原刺激的反应，然而PCV2对於PBL的存活率或细胞凋亡率则无显著影响。
