Common primitive-definitive hematopoietic precursors vs. Definitve hematopoietic progenitor cells
ABSTRACT: Transcriptional profiling of mouse ES cell-derived hemaopoitic cells comparing common primitive-definitive hematopoietic precursors (CD41SP) with definitve hematopoietic progenitor cells (KA45) RNA isolated from two separate experiments was pooled and used for comparison
Project description:We previously demonstrated that hematopoietic stem cell (HSC)-like cells are robustly expanded from mouse embryonic stem (ES) cells by enforced expression of Lhx2, a LIM-homeobox domain (LIM-HD) transcription factor. Here we established an ES cell line which conditionally expressed Lhx2 by Tet-On system. The ES cells were differentiated into HSC-like cells by Lhx2 expression. Lhx2-regulated genes were identified by comparing the HSC-like cells with those cultured in the absence of Lhx2 expression. Mouse ES with inducible Lhx2 were differentiated on OP9 stromal cells into hematopoietic lineage. On day 5 of the differentiation induction,Lhx2 expression was started by the addition of doxycycline (dox) and the cells were cultured on OP9 stromal cells in the presence of IL-6 and SCF. On day 20, HSC-like cells were harvested and re-seeded onto OP9 stromal cells in the absence of Lhx2 expression by dox-removal for 3 days. these cells were compared with the original HSC-like cells.
Project description:Comprehensive gene expression analysis in BM-resident stromal cells was performed for an overview of BM environmental change caused by total body irradiation (TBI). Total RNA samples collected from BM-resident stromal cells with or without TBI were subjected to high sensitivity DNA microarray assays Three-condition experiment: Unirradiated, 1 day after TBI and 3 days after TBI. Bone marrow stromal cells were obtained from C57BL/6 mice (n = 6) either non-irradiated or after 9.5 Gy irradiation at indicated times.
Project description:The change of mRNA expression in murine immortalized podocyte were analyzed after miR-26a silencing. These results provide a basical information of molecular pathology in podocyte biology. Mouse podocytes immortalized by temperature sensitive SV40 were used. Podocyte cultures grown at 33 °C were trypsinized and then cultured with RPMI-1640 without antibiotics in 24-well plates at 60–70% confluence for 2 days. On day 3, an anti-miR negative control (40 pmol) or the miR-26a miRNA inhibitor (40 pmol) was transfected to podocytes. The cells were analyzed after culturing for 24 hour.
