卵母細胞在成熟和受精過程中，細胞骨架發生一系列明顯的變化，微管是一種重要的細胞骨架成分，對于哺乳動物卵母細胞減數分裂的完成、精子的運動、雌雄原核的結合是必不可少的。 -
In order to investigate the role of mannose receptor ( mr ) of human sperm, the zona free hamster eggs were pre - incubated with purified mr ( pmr ) isolated from motile human sperm by mannose - agarose gel affinity chromatography. the ultrastuctural alteration and cortical granule exocytosis of the eggs were then observed by transmissian electron microscope and tritc - lca immunofluorescence microscope, respectively. the mice were immunized with pmr and the antiserum was raised. after capacitation and induction of the acrosome reaction, the human spermatozoa and oocytes were incubated with the antiserum. then the sperm penetration assay was undertaken
為了進一步探討人精於mr在精卵融合中的作用，本文採用改良后的甘露糖-瓊脂糖凝膠親和層析法分離純化人精子mr ，並將提純的人精子甘露糖受體（ purifiedmannosereceptor ， pmr ）作用於去透明帶的金黃地鼠卵母細胞，運用透射電子顯微鏡技術和羅丹明偶聯的兵豆凝集素（ tritc - lca ）免疫熒光標記技術觀察pmr對卵子的影響。
