The transforming growth factor-β superfamily, a large group of highly conserved growth factors including TGF-βs, activins and BMPs, regulate a wide variety of cellular functions such as proliferation, differentiation, apoptosis and migration. Signals from these growth factors are transduced by a group of Smad proteins. To date, there are nine vertebrate Smads, including the receptor-activated Smads , Smadsl-3, 5 and 8, the common mediator Smad4 and Smad4β, and the inhibitory Smads, Smad6 and 7. Signaling is initiated when the ligand induces assembly of a heteromeric complex of type Ⅱ and type Ⅰ TGFβ receptors. Then R-Smads are directly phosphorylated by activated type I TGF-β receptors.
在多种SMADS中，SMAD5令我们产生兴趣，基于三个原因：1、Smad5基因敲除胚胎中发现卵黄囊的异位造血以及CFU-GM祖细胞数目增加，表明SMAD5可能是早期造血发育的负向调控基因。；2、应用反义核酸封闭Smad5可以逆转TGF-β对祖细胞增殖的抑制效应，表明它可能介导TGF-β信号转导，后者的异常，包括某些SMADS的功能异常，和白血病紧密相关；3、Smad5基因定位在人染色体5q21，此区域的缺失和急性髓系白血病和骨髓增生异常综合症相关，因此，Smad5被怀疑为白血病抑制基因。

chorion laeve：平滑绒毛膜
胎膜的外层是绒毛膜,在发育过程中缺乏营养供应而逐渐萎缩成为平滑绒毛膜(chorion laeve). 胎膜的内层为羊膜,与覆盖胎盘、脐带的羊膜层相连接. 至妊娠晚期,平滑绒毛膜与羊膜紧密相贴,但可以完全分开. 妊娠14周末,羊膜与绒毛膜的胚外中胚层连接封闭胚外体腔,

complete denture：全口义齿
全口义齿(Complete denture)是为牙列缺失患者制作的义齿. 全口义齿由基托和人工牙两部分组成. 全口义齿靠义齿基托与黏膜紧密贴合及边缘封闭产生的吸附力和大气压力产生固位,吸附在上下颌牙槽嵴上,以恢复患者的面部形态及功能(图1-1).
