The syndrome seems to result from disturbances of the caudal mesoderm before the fourth week of gestation. This includes the caudal cell mass and the cloaca, what explains the associated anomalies of the genitourinary tract (24%) and lower gastrointestinal tract.
本病是妊娠第4周之前尾部中胚层的紊乱所致,包括马尾细胞团和泄殖孔,这解释有24%的病例伴有泌尿生殖道畸形和下胃肠道畸形。

At the fifth passage, two cell strains were made into cell suspension at l×10^9L^(-1). 0.5 mL was subcutaneously incubated at the inguina of each rat for 8 weeks. Amplified cells were cultured in PGC culture medium and non-adherence culture flask till idiosome formed, adhered and differeotiated.
体内实验取连续传5代的2个细胞株,分别制备浓度为l×10^9L^(-1)的细胞悬液,于每只小鼠两侧腹股沟处皮下各接种0.5 mL,培养8周体外分化采用无私附特性的培养瓶和除去白血病抑制因子的原始生殖细胞培养液,以脱饲养层法悬浮培养扩增的细胞,直到拟胚体形成及贴壁分化。

amphithecium:周层
当胚细胞已发育成20-30个细胞时,其上半部的细胞作平周壁的分裂成为中心部分的蒴内层(endotecium)和包围蒴内层的蒴周层(amphithecium)等二层细胞群. 前者后来发育成孢子囊和蒴轴,后者发育成气室、蒴壁、蒴齿和蒴盖. 孢蒴和蒴柄连接的部分呈圆锥形,
