Project description:We discovered that mice that lack Lsd1 in hematopoietic cells were exhibited increased frequencies of CD150+ CD48- lin- c-Kit+ Sca-1+ LT-HSCs, but completely lacked the lin- c-Kit+ Sca-1- myeloid progenitor compartment. To determine the genes altered by Lsd1-loss, CD150+ CD48- lin- c-Kit+ Sca-1+ LT-HSCs from Lsd1fl/fl and Lsd1fl/fl Mx1Cre mice were FACS-purified to be analyzed by gene expression profiling.
Project description:Analysis of MHCII-high (MHCII-hi) and MHCII-low (MHCII-lo) hematopoietic stem cells (Lineage-Sca-1+c-Kit+CD150+Flt3-CD48-). The two population of hematopoietic stem cell (HSC) were purified from the bone marrow of 12 months old (12 mo) mice. Results provide insight into the role of MHCII in HSC.
Project description:Analysis of MHCII-high (MHCII-hi) and MHCII-low (MHCII-lo) hematopoietic stem cells (Lineage-Sca-1+c-Kit+CD150+Flt3-CD48-). The two population of hematopoietic stem cell (HSC) were purified from the bone marrow of 5 months old WT mice (Ctrl). Results provide insight into the role of MHCII in HSC.
Project description:Purpose: The goals of this study are to elucidate the underlying mechanism for the activation of HSCs Methods: After wild type (WT) HSCs (CD150+ CD48- EPCR+ Lineage-) were treated with 5-fluorouracil (5-FU), 100 cells of HSCs were sorted. Moreover, after the culture with or without Nifedipien, cultured HSC fraction (CD150+ CD48- EPCR+ c-kit+ Sca-1+ Lineage-) were sorted. These cells were subjected to mRNA sequence using Next-seq (n>3). The sequence reads that passed quality filters were analyzed by CLC genomic workbench.
Project description:Analysis of MHCII-high (MHCII-hi) and MHCII-low (MHCII-lo) hematopoietic stem cells (Lineage-Sca-1+c-Kit+CD150+Flt3-CD48-). The two population of hematopoietic stem cell (HSC) were purified from the bone marrow of mice at 3 months post 5 Gy total body irradiation (IR). Results provide insight into the role of MHCII in HSC.
Project description:Here, we present a Small RNA-Seq dataset of isolated mouse hematopoietic stem cells (HSC LSK slam; Lineage- Sca-1+ c-Kit+ CD150+CD48-) of Meg3 KO (induced MxCre Meg3mat flox/pat wt) and control (induced MxCre) cells
Project description:To study the role of the receptor Neo1 in Hematopoietic stem cells (HSC) we transplanted Neo1 deficient bone marrow and wildtype controls on a CD45.2 background into lethally irradiated CD45.1 recipients. Either 4 or 15 months after transplantation we isolated HSC (Lineage -, Sca-1+, c-Kit+, Cd150+, CD48-, CD34-, CD45.2+) to identify molecular differences due to Neo1 deficiency and found a loss of HSC quiescence and signatures associated with decreased stem cell function.
Project description:To investigate the role of the transcription factor ERG in hematopoiesis we generated Erg heterozygous knockout and conditional Erg knockout mice. We found that several hematopoietic cell types were decreased in these mice. To define Erg downstream target genes in hematopoietic stem cells, we sorted Lineage-, Sca-1+, c-kit+, CD150+, CD48- cells from Erg +/- mice for gene expression analysis. To define Erg downstream target genes in hematopoietic progenitors, we sorted multipotent progenitors (Lineage-, Sca-1+, c-kit+, CD150-) from Erg -/- mice for gene expression analysis.
