由于脂肪组织与骨髓同为中胚层起源的组织，那么能否从脂肪组织中获得间充质干细胞，而且也具有多分化潜能呢？

Because both fat tissue and bone marrow are tissues originated from mesoderm, so whether MSCs could be obtained from fat tissue as well, which also have multi - lineage differentiation potential?

间充质干细胞（MSC）起源于中胚层，主要位于成体骨髓和人胎儿脐血，与造血干细胞共存。

Mesenchymal stem cell (MSC), originating from mesoblast, resides mainly in post-natal bone marrow as well as human umbilical cord blood, and coexists with hematopoietic stem cell (HSC).

CD44是属于黏附因子家族的跨膜糖蛋白，它广泛表达于多种内皮细胞、间充质细胞、造血干细胞及中胚层来源的细胞和组织。

CD44 is a family of trans-membrane glycoprotein that is widely expressed in many tissues derived from epithelial, mesenchymal, hematopoietic and mesodermal origins.
