Endometrial assembloid model reveals endometrial adenogenesis regulation by estradiol-driven WNT7B expression [bulk RNA-seq]

Project description:Little is known about the adenogenesis of human endometrial glands. This study explored endometrial adenogenesis using a novel three-dimensional endometrial assembloid model that integrates human endometrial organoids (EOs) and human endometrial stromal cells (HESCs). The model effectively recapitulated endometrial tubular gland formation, underscoring the critical role of stromal-epithelial interactions. Transcriptomic analyses identified WNT7B as a key intrinsic regulator for EO-derived tubular gland formation, which is extrinsically regulated by TGFβ1-VDR interaction between HESCs and EOs. Estradiol stimulated endometrial gland development via WNT7B downregulation in EOs. This finding was validated in an estradiol-stimulated mouse model and clinical samples from women undergoing in vitro fertilization (IVF) cycles. Uterine-specific WNT7B knockout in mice further confirmed its inhibitory role in endometrial gland development. This study offers insights into endometrial adenogenesis and potential therapeutic targets for related endometrial disorders.

Endometrial assembloid model reveals endometrial adenogenesis regulation by estradiol-driven WNT7B expression [scRNA-seq]

Project description:To establish an in vitro endometrial co-culture model, endometrial organoid was co-cultured with endometrial stromal cells in a 3D hydrogel matrix. During this co-culture process, tubular gland development was identified from endometrial organoids, which showed the molecular, morphological and functional properties of human endometrial glands. To further characterize the genetic drive for this phenomenon, we conducted single-cell RNA sequencing analysis at day 1 and day 9 after co-culture.

Endometrial profile of low-dose estradiol and tamoxifen combination therapy

Project description:Combination therapy with estrogen and a selective estrogen receptor modulator (SERM) is a promising approach to safely alleviate important side effects related to estrogen deficiency in women at high risk for breast cancer. Data related to endometrial safety of estrogen+SERM co-therapies are limited, however. The primary goal of this study was to evaluate the endometrial profile of low-dose E2 and Tam alone and in combination. In this study 16 postmenopausal female cynomolgus macaques were randomized to receive placebo, low-dose micronized estradiol (E2, 0.25 mg/1800 kcal), the SERM tamoxifen (Tam, 20 mg/1800 kcal), or E2+Tam in a parallel-arm design. Endometrial samples were collected after 4 months of treatment and used for microarray analysis.

Single-cell RNA Sequencing of Endometrial Assembloid Cultures

Project description:Decidual remodelling of midluteal endometrium leads to a short implantation window after which the uterine mucosa either breaks down or is transformed into a robust matrix that accommodates the placenta throughout pregnancy. To gain insights into the underlying mechanisms, we established and characterised endometrial assembloids, consisting of gland organoids and primary stromal cells. Single-cell transcriptomics revealed that decidualized assembloids closely resemble midluteal endometrium, harbouring differentiated and senescent subpopulations in both glands and stroma. We show that acute senescence in glandular epithelium drives secretion of multiple canonical implantation factors, whereas in the stroma it calibrates the emergence of anti-inflammatory decidual cells and pro-inflammatory senescent decidual cells. Pharmacological inhibition of stress responses in pre-decidual cells accelerated decidualization by inhibiting senescence and mesenchymal-epithelial transition, processes involved in endometrial breakdown and regeneration, respectively. Accelerated decidualization resulted in entrapment of co-cultured human blastocysts in a largely static decidual matrix. By contrast, the presence of senescent decidual cells created a dynamic implantation environment, enabling embryo expansion and attachment, although their persistence led to gradual disintegration of assembloids. Together, our findings demonstrate that senescence controls endometrial fate decisions at implantation and highlight how endometrial assembloids may accelerate the discovery of new treatments to prevent reproductive failure.

RNA-seq of Wnt7b overexpressing bone

Project description:We report the application of RNA sequencing technology for high-throughput profiling of gene expression in Wnt7b overexpressing bone and wide-type bones.To increase Wnt7b in bone we crossed 9.6kb DMP1-Cre mice and R26-Wnt7b mice. 9.6kb DMP1-Cre; R26-Wnt7b mice were set as OE mice meanwhile their littermates of R26-Wnt7b were controls (Ctrl). Owing to heterozygotes and homozygotes of OE mice didn’t show any different phenotypes all OE mice used in this study were homozygotes. Total mRNA of femur was collected from 8-week-old OE and Ctrl mice respectively. Fresh femur samples without soft tissues were rapidly collected within 2 min after euthanasia. And then samples were immediately transported into a sterile 10cm culture dish containing cold PBS, followed with articular cartilage removal via sterile lancets within 5 min, being flushed 3 times using sterile cold PBS to remove marrow cells and being chopped into 2~5mm fragments using sterile scissors. About 200mg bone fragments were collected into a sterile mortal containing 1ml liquid nitrogen and then were crushed and homogenized using a sterile pestle within 5 min, followed by a sterile scalpel until the tissue was adequately homogenized. Homogenized samples were collected into a 2-ml sterile tube, followed with 1 ml TRIzol ® (Invitrogen, CA, USA) solution added. Then all the extraction procedures were conducted according to manufacture’s instructions for RNA extraction from homogenized tissues. After quality checks they were subjected to the high-throughput RNA-sequencing. Every group consists of 3 replicates which were from 3 different mice.
