Mesenchymal stem cells (MSCs) are attractive candidates for clinical therapeutic applications. Recent studies indicate MSCs express active Toll-like receptors (TLRs), but their effect on and the underlying mechanisms remain unclear. In this study, we found that, after treating human umbilical cord with various TLR ligands, only TLR3 ligand, poly(I:C), could significantly increase expression of cyclooxygenase-2 (COX-2). Furthermore, poly(I:C) enhance MSCs' anti-inflammatory macrophages. Next,...

Intrauterine adhesions (IUA), characterized by endometrial fibrosis, is a common cause of uterine infertility. We previously demonstrated that partial epithelial-mesenchymal transition (EMT) and the loss epithelial homeostasis play vital role in development fibrosis. As pro-survival strategy maintaining cell tissue homeostasis, macroautophagy/autophagy, conversely, may participate this process. However, autophagy fibrosis remains unknown. Here, we defective endometria IUA patients, which...

Abstract Macrophages are a key and heterogeneous cell population involved in endometrial repair regeneration during the menstrual cycle, but their role development of intrauterine adhesion (IUA) sequential fibrosis remains unclear. Here, we reported that CD301 + macrophages were significantly increased showed most active interaction with profibrotic cells endometria IUA patients compared normal by single‐cell RNA sequencing, bulk experimental verification. Increasing promoted differentiation...

Abstract Background Stanniocalcin-1(STC-1) is up-regulated in several cancers including gastric cancer. Evidences suggest that STC-1 associated with carcinogenesis and angiogenic process. However, it unclear on the exact role for inducing angiogenesis tumorigeneisis. Method BGC/STC cells (high-expression of STC-1) BGC/shSTC (low- expression were constructed to investigate effect xenograft tumor growth vitro vivo . ELISA assay was used detect vascular endothelial factor (VEGF) supernatants....

Although some new subsets endometrial macrophages have been identified, their origins functions remain to be further explored. In this study, we employed single-cell sequencing analyze patients with intrauterine adhesion (IUA) caused by We identified unique subset distinguished expression GATA6, marker indicative cavity macrophages....

Intrauterine adhesions (IUAs), also known as Asherman's syndrome (AS), represent a significant cause of uterine infertility for which effective treatment remains elusive. The endometrium's ability to regenerate cyclically depends heavily on the growth and regression its blood vessels. However, trauma endometrial basal layer can disrupt subepithelial capillary plexus, impeding regeneration. This damage results in replacement native cells with fibroblasts myofibroblasts, ultimately leading...

In humans, a subset of placental cytotrophoblasts (CTBs) invades the uterus and its vasculature, anchoring pregnancy ensuring adequate blood flow to fetus. Appropriate depth is critical. Shallow invasion increases risk complications, e.g., severe preeclampsia. Overly deep invasion, hallmark placenta accreta spectrum (PAS), preterm delivery, hemorrhage, death. Previously rare condition, incidence PAS has increased 1:731 pregnancies, likely due rise in uterine surgeries (e.g., Cesarean...

Epithelial-mesenchymal transition (EMT) plays a specific role in the migration of tumor cells. Both estrogen and midkine (MK) have been thought to be important factors promoting progression non-small-cell lung cancer (NSCLC) can enhance EMT. Some evidence indicated correlation between estradiol (E2) MK, but precise mechanism on their interreaction is unknown. Here, we try clarify whether how E2 regulates MK expression promote We found that increased mRNA adenocarcinoma cells LTEP-a2 A549...

Abstract Intrauterine adhesions (IUAs), the leading cause of uterine infertility, are characterized by endometrial fibrosis. The management IUA is challenging because pathogenesis disease largely unknown. In this study, we demonstrate that mRNA and protein levels high mobility group AT-hook 2 (HMGA2) were increased nearly 3-fold (P < 0.0001) 5-fold = 0.0095) in epithelial cells (EECs) patients (n 18) compared to controls. vivo vitro models fibrosis also confirmed overexpression HMGA2...
