Immunoelectron microscopy of mammary gland tissue from lactating rats investigating potential structural interactions between mature lipid droplets, as indicated by peripheral labeling with adipophilin (smaller gold particles) and elements of the trans-Golgi network, identified by TGN38 (a transmembrane trans-Golgi protein) staining (larger gold particles). Note that trans‐Golgi cisternae in lactating mammary cells contain large amounts of casein and other milk proteins and are grossly expanded due to the osmolarity of the secreted fluid.

对哺乳期大鼠乳腺组织进行免疫电子显微镜观察，研究成熟脂滴与跨高尔基网络元素之间的潜在结构相互作用。脂滴通过周围标记的脂肪亲和素（较小金颗粒）进行标识，而跨高尔基网络元素则通过TGN38（一种跨膜高尔基蛋白）染色（较大金颗粒）进行识别。值得注意的是，在哺乳期乳腺细胞中的跨高尔基池含有大量的酪蛋白及其他乳蛋白，并因分泌液的渗透压而显著扩张。
