【摘要】 为研究奶山羊乳腺的胚后形态发育,采用活细胞荧光标记法结合激光共聚焦显微技术,观察奶山羊乳腺发育中内质网和线粒体的变化。结果显示:腺上皮细胞内质网和线粒体在妊娠初期和中期数量较少,妊娠晚期开始逐步增加,泌乳中期达到高峰并维持在一个较高的水平上,退化期迅速下降,逐渐恢复到妊娠前状态;退化期乳腺上皮细胞内仍保持一定数量的细胞器,以维持细胞的正常机能和活动。更多还原

【Abstract】 To consummate the study of postembryonic morphological development of dairy goat mammary gland, the changes of endoplasmic reticulum and mitochondria during mammary growing were observed with live cell fluorescent labeling and laser confocal microtechnique on the subcellular level.The results showed that the quantity of endoplasmic reticulum and mitochondria of mammary epithelium cells were fewer in early and mid-pregnancy, increased step by step after late pregnancy, reached the peak in mid-lactation and retained in the high level, decreased quickly in involution and recovered to the level of pre-pregnancy.To maintain the normal activity and function of cells, there were still a certain proportion of organelles in involuting epithelium cells .更多还原
