下泌尿生殖道(LUT)中的上皮 - 层相互作用是女性,阴道和子宫发育的前列腺和精液发育不可或缺的一部分,并且两性的尿道发育是不可或缺的。分离的LUT基质和上皮的基因表达分析具有LUT发育的揭示机制,但是此类研究被每个组织室内包含的异质和不确定的细胞亚种群混淆。我们使用原位杂交来合成同性恋小鼠LUT后17天的高分辨率分子地图集。我们鉴定出标记精液囊泡,射精管,前列腺,尿道和阴道的选择性细胞群,将这些组织细化为16个基质和8个上皮子分室。这些结果为绘制LUT基因表达模式提供了强大的工具,并揭示了以前未表征的子组件,该子室可能在LUT开发中扮演机械作用,我们以前没有意识到。
Epithelial-stromal interactions in the lower urogenital tract (LUT) are integral to prostatic and seminal vesicle development in males, vaginal and uterine development in females, and urethral development in both sexes. Gene expression profiling of isolated LUT stroma and epithelium has unraveled mechanisms of LUT development, but such studies are confounded by heterogeneous and ill-defined cell sub-populations contained within each tissue compartment. We used in situ hybridization to synthesize a high-resolution molecular atlas of 17 days post coitus fetal mouse LUT. We identified mRNAs that mark selective cell populations of the seminal vesicle, ejaculatory duct, prostate, urethra and vagina, subdividing these tissues into 16 stromal and 8 epithelial sub-compartments. These results provide a powerful tool for mapping LUT gene expression patterns and also reveal previously uncharacterized sub-compartments that may play mechanistic roles in LUT development of which we were previously unaware.
