We assessed implantation-associated quantitative changes in peripheral blood and endometrial T lymphocytes throughout epitheliochorial placenta formation.
T-cell subsets were investigated in 10-, 15-, 20-, 30-, and 40-day pregnant and non-pregnant sows by flow cytometry and immunohistochemistry.
Endometrial total T, T cytotoxic (Tc), and T helper (Th) cells were in peak numbers at the attachment phase of implantation and Tc cells persisted in high proportions up to placental establishment. The number of gammadelta T lymphocytes was relatively small and implantation-independent. In situ, T cells increased in number with the advancement of implantation and formed T-cell clusters with implantation phase-dependent location. Percentages of peripheral blood T cells were not significantly changed throughout the implantation.
Superficial and adeciduate implantation of pigs has a profound effect on the number of total T, Tc, and Th cells and pattern of distribution of endometrial T cells in situ.
我们评估了在整个上皮绒毛膜胎盘形成过程中,外周血和子宫内膜T淋巴细胞与着床相关的定量变化。
通过流式细胞术和免疫组织化学,对怀孕10天、15天、20天、30天和40天的母猪以及未怀孕母猪的T细胞亚群进行了研究。
子宫内膜总T细胞、细胞毒性T细胞(Tc)和辅助性T细胞(Th)在着床附着期数量达到峰值,并且Tc细胞在胎盘形成前一直保持高比例。γδT淋巴细胞数量相对较少,且与着床无关。在原位,T细胞数量随着着床进程增加,并形成了与着床阶段相关位置的T细胞簇。在整个着床过程中,外周血T细胞百分比没有显著变化。
猪的浅表性和非蜕膜性着床对子宫内膜总T细胞、Tc细胞和Th细胞数量以及原位子宫内膜T细胞的分布模式有深远影响。
