一项最新发现能够增加高龄女性的受孕几率。乔纳森·蒂利(Jonathan Tilly)可能已找到一种减缓女性生物钟进程的新方法。在3月发表的一篇论文中,这位哈佛大学的生殖生物学家及其同事报告称,成年女性的卵巢里仍携带卵原干细胞——这一机制很可能是延长女性受孕年龄的关键。女性的生育能力受限于卵子的总供应量,以及这些卵子在女性四十岁以后的品质。蒂利在干细胞(干细胞是指能够分化或发育成其他细胞的细胞)领域的工作可以解决这 A recent discovery can increase the chances of conception for older women. Jonathan Tilly may have found a new way to slow the progression of the female’s biological clock. In a March paper, the Harvard reproductive biologist and colleagues reported that adult women still carry egg-derived stem cells in their ovaries - a mechanism that is likely to be the key to prolonging the age of female fertility. Female fertility is limited by the total supply of eggs and the quality of these eggs after the forties. Tilly works in the field of stem cells (stem cells are cells that can differentiate or develop into other cells) that can solve this
