In its earliest stages, after 10–14 weeks' gestation, it consists of aggregates of mesenchymal cells that are condensed around proliferating primitive blood vessels.Following this stage, the stellate-shaped preadipocytes are organized into lobules that contain a rich network of proliferating capillaries. At later stages (14–24 weeks' gestation), small oil red O-positive and sudanophilic lipid droplets appear in these cells, gradually converting them to rounded or spherical, multivacuolated lipoblasts. Intracellular glycogen is usually present at this stage of development. The multiple lipid droplets then fuse to form a single vacuole and displace the nucleus marginally, forming the mature fat cell, or lipocyte.
脂肪细胞的发育过程:原始的间充质细胞——星状的前脂肪细胞——圆形或球形多空泡脂肪母细胞——空泡融合形成成熟的脂肪细胞
成熟脂肪细胞以前的阶段都可以称之为脂肪母细胞,但仅多空泡脂肪母在光镜下容易识别
