In the meantime, the uterus goes through two phases: the menstrual and proliferative phase.

与此同时，子宫经历着两个时期：月经期和增殖期。

This heralds the start of phase two of the menstrual cycle, the proliferative, or pre-ovulatory phase, which typically lasts from days 6-14 of the cycle.

这预示着月经期第二阶段的开始，即增殖或排卵前阶段，通常期的第 6-14 天。

It's followed by the proliferative phase, during which the rising levels of ovarian estrogen make the functional layer of the endometrium thicken and sprout endometrial glands.

之是增殖期，伴随卵雌激素的上升，子宫内膜功能层增厚，子宫内膜腺体生长。

In many tissues, continuous proliferation is restricted to a subpopulation of cells, the stem cells, which undergo self-renewal, as well as differentiation, into cell types with a more restrictive proliferative potential.

在许多组织中，增殖仅限于细胞亚群，即经历自我更新以及化的干细胞形成具有更多限制性增殖潜力的细胞类型。

Proliferative verrucous leukoplakia can turn into a particular type of squamous cell cancer called verrucous carcinoma, and it's also sometimes called snuff-dipper's cancer since it is more common among users of snuff and other forms of chewing tobacco.

增生性疣状白斑可发展成一种特殊的鳞状细胞癌，即疣状癌，有时也叫作“鼻烟”癌，因为这在鼻烟和其它形式的嚼烟使用者中更常见。
