Project description:We aimed to investigate the effects of maternal heat stress on the expression of differentilally expressed genes in th placenta, fetal duodenum and jejunum
Project description:Here, we used single-cell RNA-sequencing (scRNA-seq) to profile intestinal epithelial only organoids (also known as enteroids) from human fetal duodenum after one passage of in vitro growth. Organoids were grown in the standard 25% LWRN media with either 100 ng/ml of epidermal growth factor (EGF) or 1 ng/ml of EPIREGULIN (EREG) added.
Project description:iPSC were obtained from DPC from TRPC6-mut patient, a idiopathic autistic patient and a control. Original DPC and iPSC obtained were submited to expression analysis in order to check if the expression pattern obtained for the iPSC cells were closer related to embyonic cells than to the original DPC DPCs were grown until reach 80-90% of confluency in DMEM/F12 media supplemented with 15% fetal bovine serum (Hyclone, TX), 1% penicillin/streptomycin, and 1% non-essential amino acids and maintained under standard conditions (37°C, 5% CO2). RNA samples were extracted from cells in passage 5 to 7. iPSC were grown until reaches 70% of confluency in mTSER medium (Stem Cells Technologies). RNA samples were extracted from cells in passage 12 to 15.
Project description:Despite the fact that we are constantly exposed to various environmental compounds, very few studies explore the impact of combined exposure to physical and chemical pollutants on reproductive health. Until now, assessment of pollutants is mostly based on the evaluation of single pollutant or combination of chemicals with common features and modes of action. In this context, numerous studies have demonstrated that steroidogenesis and gametogenesis, the main testicular functions, are well-known to be sensitize by endocrine disruptors (as Bisphenol A) and DNA-damaging agents (as γ-rays) respectively. In this study, we aim to investigate short and long term testicular transcriptionnal alterations of combined fetal exposure to well-known environmental toxicants: γ-rays (RAD) and BPA. To discriminate specific signatures of BPA or RAD exposure after combined exposure and evidence the type of synergisms between this pollutants, we performed transcriptomic analyses on testis exposed to BPA or RAD alone and co-exposed with BPA and RAD and compared gene expression with control condition. For this, we exposed pregnant mice from 10.5 dpc to 18.5 dpc to 10µM of BPA (in drinking water) and/or we irradiated mice at 12.5 dpc to 0.2 Gy. We performed transcriptomic analyses on fetal testis (18.5 dpc) and adult testis (3 months) to evaluate short and long term cell response after in utero exposure.
Project description:We used scRNAseq to profile CD71/CD24low fetal liver erythroid progenitor cells isolated by 2 distinct methods: FACS and immunomagnetic isolation. Cells from both isolation methods were hashtagged using Biolegend mouse hashtag antibodies and library prepped together on the 10X chromium platform with the 3'RNA v3 kit. We also performed CITE-seq to profile proteogenomic expression of CD117 and CD71 on lineage-depleted mouse fetal liver erythroid progenitor cells. CITE-seq was performed through a separate library prep on the 10X chromium platform with the 3'RNAv3 kit.
Project description:Transcriptional profiling of duodenum from non-obese patients and patients with morbid obesity comparing non-insulin resistance vs. insulin resistande. Goal was to determine the involvement of the duodenum in the development of insulin resistance and the possible influence of obesity.
