Project description:As a first step for identifying hypothetical splenic stem cells for nonhematopoietic cells, densely-packed colony-forming cells were isolated from mouse spleen. Those which we designated as Splenic Adherent Colony-Forming Cells (SACCs) are positive for some of stem cell markers such as alkaline phosphatase and SSEA-1 antigen. We herewith determined global expression profiles of SACCs and control splenic adherent cells.

Project description:We performed high throughput RNA-sequencing on KSHV-infected blood and lymphatic Endothelial Colony-Forming Cells at 48hpi to identify differences in gene expression induced by KSHV in these two cell types.

Project description:Derivation and expansion of human umbilical cord blood-derived endothelial colony forming cells under serum-free conditions - a transcriptome analysis. Endothelial colony forming cells (ECFCs) were isolated from term umbilical cord blood units. ECFCs were expanded under standard, fetal bovine serum (FBS) containing endothelial medium, or transferred to chemically defined endothelial media without FBS. Microarray expression profiling was applied to compare the transcriptome profiles in FBS-containing versus FBS-free culture.

Project description:Cultured cancer cells exhibit substantial phenotypic heterogeneity when measured in a variety of ways such as sensitivity to drugs or the capacity to grow under various conditions. Among these, the ability to exhibit anchorage-independent cell growth (colony forming capacity in semisolid media), has been considered to be fundamental in cancer biology, because it has been connected with tumor cell aggressiveness in vivo such as tumorigenic and metastatic potentials, and also utilized as a marker for in vitro transformation. Although multiple genetic factors for anchorage-independence have been identified, the molecular basis for this capacity is still largely unknown. To investigate the molecular mechanisms underlying anchorage independent cell growth, we have used genome-wide DNA microarray studies to develop an expression signature associated with this phenotype. Using this signature, we identify a program of activated mitochondrial biogenesis associated with the phenotype of anchorage-independent growth and importantly, we demonstrate that this phenotype predicts potential for metastasis in primary breast and lung tumors. Keywords: Breast cancer cell lines with various colony-forming ability To develop an expression signature reflecting the capacity for anchorage-independent cell growth, we first carried out colony formation assays with 19 breast cancer cell lines in suspension culture dish with methyl-cellulose containing media. Starting with 20,000 plated cells, five cell lines (MDA-MB-361, HCC38, ZR75, Hs578T and BT483) gave rise to less than 20 colonies, while 8 cell lines (MCF7, MDA-MB-231, BT20, SKBR3, MDA-MB-435s, T47D and BT474) showed formation of more than 500 colonies. The rest of the cell lines showed an intermediate phenotype in colony forming ability (20-200 colonies; HCC1143, HCC1806, HCC1428, MDA-MB-453, CAMA1, BT549 and MDA-MB-157). Among 19 cell lines, 11 cell lines have duplicates of expression data in a different batch. We removed the batch effect of this Affymetrix expression data using ComBat according to the instruction of http://statistics.byu.edu/johnson/ComBat/Abstract.html. Therefore, this dataset is a combined and standardized data that are originally RMA formatted.

Project description:Human induced pluripotent stem (hiPS) cells and human embryonic stem (hES) cells differentiate into cells of the endothelial lineage, but derivation of cells with human umbilical cord blood endothelial colony forming cell (ECFC)-like properties has not been reported. Here we describe a novel serum- and stromal cell-free ECFC differentiation protocol for the derivation of clinically relevant numbers of ECFCs (> 108) from hiPS and hES cells. We identified NRP-1+CD31+ selected cells that displayed a stable endothelial phenotype exhibiting high clonal proliferative potential, extensive replicative capacity, formation of human vessels that inosculated with host vasculature upon transplantation, but lacking in teratoma formation in vivo. We also identified NRP-1-VEGF165-KDR-mediated activation of KDR as a critical mechanism for the emergence and derivation of ECFCs from hiPS and hES cells. This protocol advances the field by generating highly replicative but stable endothelial cells for use as a potential cell therapy for human clinical disorders. Transcriptome sequencing of undifferentiated day 0 hiPS cells, Day 3 differentiated hiPS-derived mesoderm proginator cells, Day 12 hiPS-derived NRP-1+CD31+ cells, Day 12 H9-hES-derived NRP-1+CD31+ cells and cord blood-derived Endothelial colony forming cells.

Project description:Endothelial colony-forming cells (ECFCs) have been reported as promising cells for regenerative medicine thanks to their angiorepair properties. Transcription factors are primary determinants of the functional capacity of the cells and TAL1 has been shown as a critical regulator of endothelial lineage in both development and adult life. However, only few (three) TAL1 targets have been identified so far in mouse and human endothelial cells. This ChIP-seq experiment was designed to identify genome binding/occupancy of TAL1 by ChIP and high throughput sequencing in primary human endothelial stem/progenitor cells.
