卵原细胞

Oogonia are the female germ cells in the ovary that have the potential to develop into oocytes.
卵原细胞是卵巢中具有发育成卵母细胞潜能的女性生殖细胞。
During fetal development, oogonia multiply and then undergo meiosis to form primary oocytes.
在胎儿发育过程中，卵原细胞会增殖然后经过减数分裂形成初级卵母细胞。
In humans, oogonia enter meiosis during the prenatal period, but arrest at prophase until puberty.
在人类中，卵原细胞在出生前即进入减数分裂阶段，但在青春期之前会停留在前期阶段。
The number of oogonia peaks around week 20 of gestation, after which they start to decrease through atresia.
卵原细胞的数量在妊娠第20周左右达到峰值，之后开始通过闭锁过程逐渐减少。
Oogonia are derived from primordial germ cells and their development is crucial for female fertility.
卵原细胞由原始生殖细胞分化而来，其发育对女性生育能力至关重要。
Errors in oogonia formation can lead to disorders such as primary ovarian insufficiency or infertility.
卵原细胞形成过程中的错误可能导致诸如原发性卵巢功能不全或不孕等病症。
The differentiation and maturation of oogonia are regulated by various hormones and growth factors.
卵原细胞的分化和成熟受到多种激素和生长因子的调控。
Studies on animal models have shown that environmental factors can impact the proliferation and survival of oogonia.
在动物模型研究中发现，环境因素能够影响卵原细胞的增殖和存活。
Oogonia contain diploid sets of chromosomes, which are halved during meiosis to produce haploid oocytes.
卵原细胞含有二倍体染色体组，在减数分裂过程中减半以产生单倍体卵母细胞。
Upon reaching sexual maturity, the arrested oogonia resume meiosis, completing the process to become mature oocytes.
当到达性成熟期时，暂停减数分裂的卵原细胞会恢复这一过程，最终发育成为成熟的卵母细胞。
