使用生殖细胞标记物 (DAZL,CVH,SSEA-1) 分析了XPGCs.
将移植的培养XPGC植入早期胚胎 (EG&KX,HH14阶段).

主要成果:

每个胚胎中平均发现了42个XPGC.
建立了三个稳定的XPGC细胞系 (一个雄性,两个雌性).
通过生殖细胞标志物表达证实了XPGC的身份.
在长期培养后,XPGCs有能力迁移到生殖腺.
与后来的PGC相比,观察到体外生长较低,但迁移潜力较高.

Gastrulation

Gastrulation

Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Zygotic Development And Stem Cell Formation

Zygotic Development And Stem Cell Formation

The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
