Despite its structural simplicity, hyaluronan exhibits a broad spectrum of biological activities. Cumulus expansion observed during oocyte maturation in mammals is also induced by hyaluronan accumulation in cumulus-oocyte complexes. It has been demonstrated that this volumetric change in cumulus-oocyte complexes correlates with the progression of oocyte maturation. We have investigated the molecular mechanism of oocyte maturation in mammals, focusing on hyaluronan accumulation in cumulus-oocyte complexes during cumulus expansion. In this review, we describe the physiological function of hyaluronan, emphasizing the progression of oocyte maturation in mammals based on our previous findings.
尽管透明质酸结构简单,但其具有广泛的生物活性。在哺乳动物卵母细胞成熟过程中观察到的卵丘扩展也是由透明质酸在卵丘-卵母细胞复合体中的积累所诱导的。已经证明,卵丘-卵母细胞复合体的这种体积变化与卵母细胞成熟的进程相关。我们研究了哺乳动物卵母细胞成熟的分子机制,重点关注卵丘扩展过程中透明质酸在卵丘-卵母细胞复合体中的积累。在这篇综述中,我们描述了透明质酸的生理功能,并基于我们之前的研究结果强调了哺乳动物卵母细胞成熟的进程。
