Expression data from human hematopoietic stem cells with different culture systems

Project description:To date, different experimental strategies have been developed for the ex vivo expansion of human hematopoietic stem (HSCs) in clinical application. However, it is still unclear to what difference in genomic function in HSCs expansion under different culture systems. In this study, we compared gene-expression profile of ex vivo expanded serum (10% FBS, fetal bovine serum) and serum-free culture systems, and then analyze molecular function of differentially expressed gene using microarray chips.

Molecular characterization of hematopoietic stem cells after in vitro amplification on biomimetic 3D PDMS cell culture scaffoldsMolecular characterization of hematopoietic stem cells after in vitro amplification on biomimetic 3D PDMS cell culture scaffolds

Project description:Hematopoietic stem cell transplantation (HSCT) is successfully applied since the late 1950s, however, its efficacy still needs to be improved. A promising strategy is to transplant high numbers of pluripotent hematopoietic stem cells (HSCs). Therefore, an advanced ex vivo culture system is needed that supports the proliferation and maintains the pluripotency of HSC to override possible limitations in cell numbers gained from donors. To model the natural HSC niche in vitro and thus, to amplify high numbers of undifferentiated HSCs, we used an optimized HSC cell culture medium in combination with artificial 3D bone marrow-like scaffolds made of polydimethylsiloxane (PDMS). After 14 days in vitro (DIV) cell culture, we performed transcriptome and proteome analysis of the whole cell populations. Ingenuity pathway analysis (IPA) indicated that our 3D PDMS cell culture scaffolds activated interleukin, SREBP, mTOR and FOXO signaling pathways as well as the HSC metabolism, which we confirmed by ELISA, Western blot and metabolic flux analysis. These molecular signaling pathways and HSC metabolism are well known to promote the expansion HSCs and are involved in their pluripotency maintenance. After selection and enrichment of immature CD34-positive/CD38-negative HSCs using FACS sorting, we could confirm our findings by another proteome analysis followed by IPA. Thus, we could show that our 3D bone marrow-like PDMS scaffolds activate key molecular signaling pathways to amplify the numbers of undifferentiated HSC efficiently ex vivo.

Expression data from different stages of hematopoietic cells development

Project description:18 different population of cells in different developmental stages in hematopoietic hierarchy have been purifyed by FACS analyses from wild type C57Bl6 mice and subjected to Micrroarray Affymetrix mouse 430.2 platform We used microarrays to compare global expression pattern in different hematopoietic cell populations to reconstruct the whole hierarchy of hematopoietic tree based on gene profiling Keywords: Hematopoietic Development

Microarray expression data of A375 cells at different density/culture system

Project description:Ferroptosis is one of the regulated cell deaths, induced by the accumulation of lipid peroxidation. Induction of ferroptosis is often influenced by the cell environment; however, much remains unknown about cellular states altering ferroptosis susceptibility. We found that melanoma cell lines become resistant to ferroptosis along with an increase in cell density. To elcidate the mechanism, we have investigated the differences in gene expression between A375 cells at different densities/culture systems.

Gene expression data of murine hematopoietic stem cells before and after in vitro culture

Project description:Isolation of long-term reconstituting hematopoietic stem cell (HSC) has been possible by utilizing flow cytometry with a combination of multiple antibodies against cell surface markers. However those cell surface phenotypes do not represent functional HSC after in vitro culture. We compared gene expression profiling of phenotypic HSC (CD48-KSL cells) before and after in vitro culture, and discovered that cultured HSC express mast cell-related genes including Cd244. After in vitro culture, phenotypic HSC can be divided into CD244- and CD244+ subpopulations, and only CD244- cells that have low mast cell gene expression and maintain HSC-related genes sustain reconstitution potential. Induction of CD244 may partially be triggered by induction of endoplasmic reticulum (ER) stress, as chemically induced ER stress signal increased CD244+ subpopulation while ER stress suppression using a molecular chaperone, TUDCA, decreased CD244+ population, which were correlated to the output of reconstitution assay. These data suggest CD244 positivity is a potent marker to exclude non-functional HSC after in vitro culture thereby useful to elucidate mechanism of functional decline of HSC during ex vivo treatment.
