胚周层

After 16 weeks growth, continuous and intact ameloblast, enamel, dentin, odontoblast was found.

生长16周的人牙胚，已经形成连续完整的成釉质细胞，牙釉质、牙本质和成牙本质细胞层。

①At the 8 weeks of fetalage, the ciliated, small mucous granule cells and rare basal cells were all differentiated from endoderm cubic cells, which was 3 weeks earlier than Gaillard's report.

①人胚胎8周时，内胚层细胞已分化出气管上皮的纤毛细胞、小粘液颗粒细胞、基底细胞很少，该结果比过去Gaillard等的报告提前3周。

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。

However, traditional beauty therapy involves a series of plastic micro-needle injection, and take up to 8-10 weeks for "mesoderm" stimulation treatment.

不过，传统的美塑疗法涉及一系列的微针注射，且需要长达8-10周的"中胚层"刺激治疗。

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。

The present case report explains echographic features of a Mesoblastic Nephroma diagnosed at the 31 weeks of pregnancy and make a brief discussion.

我们的这个病例就提供了一例在孕31周诊断的中胚层肾瘤的回声特征并做了简单的讨论。

However, traditional beauty therapy involves a series of plastic micro-needle injection, and take up to 8-10 weeks for "mesoderm" stimulation treatment.

不过，传统的美塑疗法涉及一系列的微针注射，且需要长达8-10周的&中胚层&刺激治疗。
