Project description:Human CB HSC enriched cells were transduced with shRNAs targeting MTA1 to identify changes in global transcription programme and understand the mechanisms behind MTA1 knock down induced phenotype.
Project description:Umbilical cord blood banking is critical for the success of umbilical cord blood transplants. Here we analyzed transcriptomic differences between 27-year cryopreserved umbilical cord blood hematopoietic stem cells (HSCs) and multipotent progenitor cells (MPPs) and those derived from fresh cord blood. We also leveraged differences in engraftment capacity to examine the transcriptomes of HSCs/HPCs defined by engraftment capacity, demonstrating the feasibility of this approach for identifying potency markers to aid in the selection of cord blood units for transplantation and revealing novel potential regulators of cord blood HSC/HPC engraftment.
Project description:The identification and manipulation of unique genes expressed in human haematopoietic stem cells (HSCs) compared with multipotent progenitors (MPPs) to augment transplantation efficacy remain largely unexplored.To identify genes potentially enriched in human HSCs, we sorted rigorously defined HSCs (CD34+CD38-CD45RA-CD90+)and MPPs (CD34+CD38-CD45RA-CD90-) from freshly isolated human cord blood for transcriptomic analysis.
Project description:Global gene expressions of human cord blood-derived 18Lineage-negative (18Lin-)CD34+CD38-CD133+GPI-80+ cells (CD34+ HSCs), 18Lin-CD34-CD133+GPI-80+ cells (CD34- HSCs) and 18Lin-CD34+CD133- cells (non-HSCs) were analyzed. Results provide an insight into the molecular mechanisms underlying the self-renewal, maintenance and differentiation of human cord blood-derived CD34+/- HSCs.
Project description:Mta1 gene expression reveals new targets and functions. Mta1 functions in p53 dependent and independent manner. Genes regulated by Mta1 in the presence and absence of p53 were indetified This expression data contains 5 different samples (MEFs) 1.wild type 2. Mta1 knockout 3. Mta1 re-expression in the knock out MEFs 4. P53 knockout and 5. Mta1 over expression in P53 knock out MEFs. Various sample comparisons were done and genes with p-value< 0.05 and fold change M-bM-^IM-% 2.0 were considered statistically significant 5 samples (triplicates of each, total 15) were analyzed. We generated pairwise comparisons between the WT vs Mta1-KO; Mta1-KO vs Mta1-KO/Mta1; P53-KO vs P53-KO/Mta1.
Project description:Single cell transcriptomic profiling (sc RNA-seq) of the two Human Hematopoietic Stem Cell Populations from cord blood: 18LinnegCD34posCD133pos (hereafter CBC1:CD34pos ) and 18LinnegCD34negCD133pos HSCs (hereafter CBC3:CD34neg). Purpose: to compare the single cells transcriptomic profiles of the two Human Hematopoietic Stem Cell Populations: CD34pos HSCs and CD34neg HSCs in order to find unique homing molecules profile. Results provide insight of highly expressed adhesion molecules in CD34neg HSCs and their crucial role in interacting with the bone marrow microenvironment.
Project description:Gene expression analysis on purified murine hematopoietic stem cells (HSCs) deficient for Special AT-rich sequence-binding protein 1 (Satb1) compared to wild-type HSCs. Analysis of gene expression of bone marrow-derived CD45.2+ CD150+cKit+Sca-1+CD4-CD8a-CD19-B220-Gr-1- HSCs from congenic recipient animals transplanted >20 weeks with either wild-type or Satb1-deficient hematopoeitic cells.
