METHODS: Spinal cord injury model produced in 42 Wistar rats on T7 by use of modified Allen's impact method (10 g x 5 cm); 3 days after injury, 20 microliters FSCS with a density of 1 x 10(5)/microliter prepared from E14 rat were injected into the epicenter of the traumatized cavity.

方法对 4 2只 Wistar成年大鼠以改良 Allen法(10 g× 5 cm)打击脊髓，3天后将孕 14天(E14 ) 5只胚胎脊髓细胞悬液 2 0 μl植入损伤空腔，移植后 2、4、6、8、10和 12周，以组织学、免疫组织化学观察移植物成活、分化及其与宿主之间关系。

Inner cell mass were separated by micromanipulator with laser micro-dissection under the microscopy.

Decidual tissue is a very complex and highly concordant tiny environment between mother and embryo during pregnancy, which is constituted of the variety cells such as extravi11ous trophoblast,endometrium cells, bone marrow cells, decidua l microphage,T cells and a few B cells and so on.

正常蜕膜组织是母-胎界面间一个非常复杂而又高度协调的微环境，它由多种细胞如侵袭至蜕膜的绒毛外滋养细胞(extravi11ous trophoblast，EVT)、子宫内膜源性细胞(如上皮细胞和血管内皮细胞)、骨髓源性细胞(如大颗粒淋巴细胞、蜕膜巨噬细胞、T细胞和少许B细胞)构成，这些细胞以及由这些细胞、母体和胎儿所分泌到蜕膜的细胞因子共同形成了母-胎间信息交流的平台，并对胚胎滋养细胞"有控性"侵袭、子宫内膜的免疫容受性、蜕膜化和胎盘的形成进行精细的调控。
