普及一下脂肪移植成活的知识

​​1. 脂肪组织游离移植后的组织学变化 脂肪组织游离移植后早期,移植脂肪组织处于缺血缺氧 状态。中华棋牌因为移植脂肪与受区没有建立良好的血液供应,脂肪细胞的营养供应便只能由组织间液的渗 透而来,然而组织间液的渗透能力有一定限制,只能渗透 150~200 μm。但是脂肪移植物中最终存 活下来的区域并不局限于由外周往内部的 150~200 μm 区域。这一结果提示在脂肪移植的后期过程 中,存在着脂肪组织的新生与血运的重建。移植后第 2 天,脂肪组织周围出现大量受区细胞浸润。

移植后 7 d,可见移植物周围有毛细血管长入,切片中毛细血管扩张,管腔内充满大量红细胞。移 植后 14 d,脂肪颗粒间隔内有较大血管生长。1 个月后,可见移植脂肪中心部位有丰富的毛细血管 分布。2 个月后,前脂肪细胞胞质内可见空泡样的脂滴形成,细胞体积增大,胞质成泡沫样改变, 细胞成脂功能活跃。注射移植后 4 个月,Bertossi 发现孤立的形态正常的脂肪细胞群已被结缔组织 所包裹,巨噬细胞仍然存在,其内包含有大量脂肪液滴和胞质颗粒。纤维化逐渐增加,移植脂肪中 心的坏死组织逐渐增多,与此同时脂肪细胞也逐渐向远离最初血供的地方生长,研究提示这些细胞 的存活可能依靠脂肪干细胞的存在。而最新研究发现,脂肪切取移植组织块中的脂肪干细胞数量要 显著高于颗粒脂肪移植组织。6 个月后,移植物的基本结构与正常脂肪组织相似。

2. 颗粒脂肪组织注射移植后的组织学变化在光镜下观察颗粒脂肪组织细胞相互分离或聚集成
