Single cell RNA sequencing and lineage tracing confirm mesenchyme to epithelial transformation (MET) contributes to repair of the endometrium at menstruation

ABSTRACT: We profile the transcriptomes of over 20,000 mouse single cells, yielding molecular definitions for mesenchymal and epithelial cell types present in the mouse uterus during post-menstrual tissue repair. We identify a novel population of fibroblasts that express genetic markers associated with both mesenchymal and epithelial phenotypes in the repairing mouse uterus. Further trajectory analysis indictates a differentiation trajectory between mesenchymal and epithelial cells indicative of a putative mesenchymal-to-epithelial transition (MET) event occuring during post-menstrual tissue repair. Our work provides a platform to further understand the roles of these cell populations in uterine physiology and disease and for comparisons between wound healing events in the endometrium and other adult tissue which are prone to fibrosis.

Menstrual fluid factors facilitate tissue repair: Identification and functional action in endometrial and skin repair

Project description:Repair after damage is essential for tissue homeostasis. Post-menstrual repair of the uterine endometrium is a unique cyclical manifestation of rapid, scar-free, tissue repair taking ~3-5 days. Skin repair post-wounding is slower (~2 weeks) and, in the case of chronic wounds, takes months/years to restore integrity. Herein, the unique ‘rapid-repair’ endometrial environment is translated to the ‘slower-repair’ skin environment. Menstrual fluid (MF), the milieu of post-menstrual endometrial repair, facilitates healing of endometrial and keratinocyte ‘wounds’ in vitro, promoting cellular adhesion and migration, stimulates keratinocyte migration in an ex vivo human skin-reconstruct model and promotes re-epithelialization in an in vivo porcine wound model. Proteomic analysis of MF identified a large number of proteins; several proteins were selected for further investigation, with the endometrium demonstrated as the source of these factors. Functionally, they promote repair of endometrial and keratinocyte wounds by promoting migration, differing significantly from currently available wound-repair treatments, which mainly promote proliferation. Development of these and other menstrual fluid factors into a ‘migration-inducing’ treatment paradigm will provide novel therapies for tissue repair.

Transcriptional dynamics of the cycling mouse uterus

Project description:The adult uterus regenerates in the human during the menstrual cycle, and remodels in the mouse during the estrous cycle. Decades of work has demonstrated that this process is controlled by cycling steroid hormones, estrogen and progesterone. However, downstream signaling pathways that link hormonal action to this regeneration and remodeling are yet to be identified in the cycling uterus. We set out to identify these pathways, with the overarching hypothesis that developmental signaling pathways are redeployed in the adult uterus to control remodeling in the mouse.

Deep sequencing of transcript levels of human embryonic stem cell derived mesothelium (epithelial and mesenchymal forms) and mesothelium from neonatal mouse E15.5 of the heart, lung, liver and gut and ChIP-seq data of the mesenchymal form of mesothelium

Project description:Mesothelium is a multipotent resident progenitor cell of the coelomic organs that functions in organogenesis, repair and possible regeneration. We used hESCs to generate mesothelium of the epithelial and mesenchymal forms. Mesenchymal derivatives of mesothelium have been previously reported to function in tissue repair by promoting and participating in angiogenesis and neovascularization. We uncovered that hESC-derived mesothelium of the mesenchymal form (MesoT) are multipotent and generate smooth muscle cells, endothelial cells and pericytes and self-assemble into vessel-like networks in vitro. MesoT cells contribute to nascent coronary vessels in the repair zone of mechanically damaged neonatal mouse hearts. MesoT cells seeded onto vascular scaffolds self-assemble into vasculature capable of supporting peripheral blood flow following transplantation. Our findings demostrate the potential utility of MesoT cells in tissue repair and vascular engineering applications.

Changes in Mouse Uterine Lumenal Epithelial Cell Transcriptome in Estrus Compared to Proestrus

Project description:The potential for xenoestrogens and other environmental chemicals to alter female reproductive function calls for the study of their affects on endogenous hormone-regulated gene expression pathways during uterine tissue remodeling which occurs as part of the menstrual/estrus cycle. However, our knowledge of these pathways is limited. Here, we characterize changes in the CD-1 mouse uterine luminal epithelial cell transcriptome during proestrus and estrus, which are regulated by estrogen and progesterone in preparation of the uterus for pregnancy. Mice were staged beginning at 6 wk of age and uterine horns were harvested at estrus and proestrus. RNA was extracted from lumenal epithelium of uterine horns. Microarray analysis identified 2,251 genes differentially expressed in estrus compared to proestrus in lumenal epithelial cells. These complement other studies where RNA was extracted from whole uterine horns of mice in estrus and proestrus (GSE43064). Beginning on postnatal day 41, female CD-1 mice were monitored for reproductive stage cycle and total RNA was isolated from lumenal epithelium of uterine horns at estrus or proestrus. Tissue was collected on postnatal days 41-61. Samples were pooled for microarray analysis as follows. Seven litters were used to generate 2 tissue pools for estrus and 2 tissue pools for proestrus. Each pool was comprised of uterine tissue RNA from n=4-5 individual mice and n=3-4 individual litters. Fluorescent labeling of RNA and hybridization of the Alexa 555-labeled (green) and Alexa 647-labeled (red) RNA samples to Agilent-026655 Whole Mouse Genome Microarray 4x44K v2 (Agilent Technology, Palo Alto, CA; catalog # G4846A) were carried out, with dye swapping for each estrus cycle stage comparison.

Gene expression profiling of uterine epithelial cells isolated from Msx1Msx2 floxed and Msx1Msx2 ablated mice on day 4 of pregnancy

Project description:Our preliminary study revealed that the homeobox transcription factors, Msx1 and Msx2, are expressed in the mouse uterus during early pregnancy. Further, conditional deletion of Msx1 and Msx2 in mouse uterus leads to implantation failure due to impaired uterine epithelial receptivity. To identify the downstream targets of Msx1Msx2 in the uterus, we performed gene expression profling of uterine epithelial cells isolated from Msx1Msx2-null mice and the corresponding controls on day4 of pregnancy (the time of implantation). The microarray results revealed elevated expression of mRNAs corresponding to several Wnts in uterine epithelium of Msx1Msx2-ablated mice. We performed conditional ablation of Msx1Msx2 in the mouse uterus using the PRcre mouse model. we isolated uterine epithelial cells from day4 pregnant mice (n=5 for each genotype). Total RNA was purified from these cells to hybridize to high density affymetrix microarrays.

Single-cell transcriptomic profiling of the neonatal oviduct and uterus reveals new insights into upper Müllerian duct regionalization

Project description:The upper Müllerian duct (MD) is patterned and specified into two morphologically and functionally distinct organs, the oviduct and uterus. It is known that this regionalization process is instructed by inductive signals from the adjacent mesenchyme. However, the interaction landscape between epithelium and mesenchyme during upper MD development remains largely unknown. Here, we performed single-cell transcriptomic profiling of mouse neonatal oviducts and uteri at the initiation of MD epithelial differentiation (postnatal day 3). We identified major cell types including epithelium, mesenchyme, pericytes, mesothelium, endothelium, and immune cells in both organs with established markers. Moreover, we uncovered region-specific epithelial and mesenchymal subpopulations and then deduced region-specific ligand-receptor pairs mediating mesenchymal-epithelial interactions along the craniocaudal axis. Unexpectedly, we discovered a mesenchymal subpopulation marked by neurofilaments with specific localizations at the mesometrial pole of both the neonatal oviduct and uterus. Lastly, we analyzed and revealed organ-specific signature genes of pericytes and mesothelial cells. Taken together, our study enriches our knowledge of upper Müllerian duct development, and provides a manageable list of potential genes, pathways, and region-specific cell subtypes for future functional studies.
