Project description:The transcriptome of LT-HSC (CD34+CD38-CD45RA+CD90+CD49f+) and ST-HSC (CD34+CD38-CD45RA+CD90-CD49f-) from healthy adult human Bone Marrow Cells were assessed by RNA-seq.
Project description:Study of the transcriptomic changes in human HSPCs under the influence of at-RA and 4-oxo-RA. Human Hematopoietic Stem and Progenitor Cells (HSPCs)(Lineage negative, CD38 negative, CD34 positive cells) were isolated from sternal bone marrow of patients who had experienced myocardial infarction or from control patients. For in vitro cultivation, cells were treated with at-RA (2.5 μM final concentration), 4-oxo-RA (2.5 μM final concentration), or the respective volume of DMSO (control) for 72 hours. After incubation period, cells were harvested for RNA extraction.
Project description:Study of the effects of at-RA and 4-oxo-RA 72h treatment on the transcriptome of human peripheral blood monocytes from healthy individuals.
Project description:Study of the effects of at-RA treatment on the transcriptome of murine Long-Term Hematopoietic Stem Cells (LT-HSCs) in the context of myocardial infarction (MI). MI was induced in female C57BL/6J mice aged 6 to approximately 12 weeks through permanent occlusion of the left anterior descending artery (LAD). Mice were intraperitoneally injected on the 1st and 2nd day after MI surgery with either 30 mg/kg body weight at-RA (Sigma-Aldrich; MI+at-RA condition), or with the corresponding amount of DMSO in phosphate-buffered saline (PBS) (MI+vehicle condition). Two days after MI, LT-HSCs (Lin-negative, Sca1-positive, c-Kit-positive, CD150-positive, CD48-negative, CD34-negative) were isolated from the bone marrow, sorted, and analyzed for their transcriptome profiles. This study aimed to understand how at-RA treatment influences gene expression in LT-HSCs following MI.
Project description:The transcriptome of WT and Rarb KO hematopoietic stem cells (HSC) after 24h in vitro culture upon retinoid treatment was assessed by RNAseq.
Project description:Study of the gene expression patterns of specific cardiac cell populations, including monocytes (CD45+, CD11b+, F4/80-, LyC6+), endothelial cells (CD45-, CD31+), macrophages (CD45+, CD11b+, F4/80+, LyC6-), and fibroblasts (CD45-, GP38+), in response to at-RA and 4-oxo-RA treatments. Female C57BL/6J mice aged 12 weeks were intraperitoneally injected with 30 mg/kg body weight at-RA (Sigma-Aldrich), 30 mg/kg body weight 4-oxo-RA (Sigma-Aldrich), or an equivalent volume of DMSO in phosphate-buffered saline (PBS) as the vehicle control. After 24 hours of injection, the mice were euthanized for analysis.
