Role of CTGF-LRP1 in Impaired Healing of Cesarean Section Incisions

ABSTRACT: Niche is a long-term complication following a cesarean section, which may increase the risk during subsequent pregnancies, and its pathogenesis remains incompletely understood. In this study, we utilized single-cell RNA sequencing to analyze 43,384 individual cells obtained from adjacent myometrium tissue of the niche (Adjacent), well-healed cesarean scar tissue (Control), and niche tissue (Niche). Our analysis revealed that fibroblasts (FB) could be classified into three subgroups. FB3 in the Niche exhibited a reduced capacity for extracellular matrix synthesis. Cell communication analysis has identified that the secretion of CTGF by Endo3 and the expression of LRP1 by FB3 are involved in the receptor-ligand interaction of uterine fibroblasts during wound healing. Our research findings were supported by tissue staining and in vitro experiments, indicating that silencing LRP1 may prevent CTGF from promoting the synthesis of extracellular matrix by primary uterine fibroblasts. Furthermore, animal models have indicated that CTGF can promote the healing of uterine scars. These results provide insights into the cellular environment and mechanistic background underlying the formation of the uterine niche and poor wound healing following a cesarean section, laying the groundwork for future investigations into therapeutic approaches for the uterine niche.

Intra-amniotic Balloon Inflation Induces an Inflammatory “Pulse” and Labor in Nonhuman Primates

Project description:Uterine stretch is thought to induce preterm labor in women with twin and higher order pregnancies, but the pathophysiology remains unclear. We investigated the pathogenesis of stretch-induced preterm birth for the first time in a pregnant nonhuman primate model. Eleven chronically catheterized pregnant monkeys (Macaca nemestrina) at 118-125 days gestation (term=172 days) received either: 1) inflation of intra-amniotic balloons (N=6) or 2) saline inoculation (N=5). Cesarean section and fetal necropsy was performed due to preterm labor or to collect tissues, except in one case where the animal delivered spontaneously, reducing samples for microarray analysis to ten (five stretch and five control animals). Amniotic fluid and maternal plasma were analyzed for multiple cytokines and prostaglandins using Luminex, enzyme-linked immunosorbent assay and Analysis of Covariance. Ribonucleic acid was extracted from the myometrium in the lower uterus at Cesarean section and analyzed by microarray and quantitative reverse transcriptase polymerase chain reaction.

Uterine injury during diestrus leads to embryo spacing defects and perturbations in the Cox-2 pathway in subsequent pregnancies

Project description:Uterine injury from procedures such as Cesarean sections (C-sections) often have severe consequences on subsequent pregnancy outcomes, leading to disorders such as placenta previa, placenta accreta, and infertility. With rates of C-section at approximately 30% of deliveries in the US that are projected to continue to climb, an understanding of the mechanisms by which these pregnancy disorders arise and opportunities for intervention are sorely needed. However, there are currently no animal models to date that comprehensively assess the consequences of uterine injury. Here we describe the first rodent model of uterine injury on subsequent in utero outcomes. We observed four distinct phenotypes: reduced implantation events, increased rates of resorption, embryo misspacing, and placenta accreta-like features of reduced decidua and expansion of invasive trophoblasts. We also show that the appearance of embryo misspacing depends entirely on the phase of estrous cycle at the time of injury, leading us to identify differences in uterine wound healing as a function of estrous. Using RNA-seq, we identified perturbations in the expression of components of the COX-2 pathway after recovery from injury, a pathway that has previously been demonstrated to play an important role in embryo spacing. Therefore, we demonstrate that uterine damage in our novel mouse model engenders many uterine changes, most notably perturbed expression of COX-2 pathway-related genes, that ultimately lead to numerous placental and embryonic developmental defects with parallels to human pregnancy disorders.

Whole-genome microarray analysis of human skin fibroblasts

Project description:Connective tissue growthfactor (CTGF/CCN2) is a matricellular protein induced by transforming growth factor-beta (TGF-beta) and intimately involved with tissue repair and overexpressed in various fibrotic conditions. We have previously shown that keratinocytes in vitro downregulate TGF-beta induced expression of CTGF in fibroblasts by an interleukin-1 alfa (IL-1alfa) dependent mechanism. With this study we want to get a better overall perspective who fibroblasts respond on TGF-beta and in a TGF-Beta stinulated system, what effect addition of IL-1 alfa have. This to understand the expression of CTGF in human fibroblasts which in turn have implications for the pathogenesis of fibrotic conditions involving the skin.
