Project description:B-cell precursor acute lymphoblastic leukemia (BCP-ALL) cells reside in the bone marrow microenvironment, where they are protected against chemotherapeutic agents. Mesenchymal stromal cells (MSCs) are key components of this supporting framework. The present study aimed to unravel whether MSCs derived from pediatric BCP-ALL patients (leukemic MSCs) differ from MSCs derived from healthy pediatric donors (control-MSCs). Therefore, we studied their gene expression profiles.

Mesenchymal stromal cells (MSCs) are key components of this supporting framework. The present study aimed to unravel whether MSCs derived from pediatric BCP-ALL patients (leukemic MSCs) differ from MSCs derived from healthy pediatric donors (control-MSCs). Therefore, we studied their gene expression profiles after 40 hours of co-culture with primary B-cell precursor acute lymphoblastic leukemia cells. MSCs were sorted using fluorescence-activated cell sorting (FACS).
Project description:Mesenchymal stem/stromal cells (MSCs) were harvested from subcutaneous adipose tissue of patients with obesity or healthy controls and expanded for 3-4 passages, and 5hmC profiles were examined through hydroxymethylated DNA immunoprecipitation sequencing (hMeDIP-seq). We hypothesized that obesity and cardiovascular risk factors induce functionally-relevant, locus-specific changes in overall exonic coverage of 5hmC in human adipose-derived MSCs.
Project description:To investigate the identity of the tumor microenvironment in acute lymphoblastic leukemia (B-ALL), the transcriptome of mesenchymal stromal cells derived from bone marrow of three pediatric patients at the onset of the disease was analyzed and compared with its normal counterpart.
Project description:The aim of the study was to get insights into transcriptional alterations in bone marrow mesenchymal stromal cells derived from acute myeloid leukemia patients We compared the global gene expression profile from AML BM-MSC (n=19) to healthy donor (HD) controls (HD BM-MSC n=4)
Project description:The aim of the study was to get insights into transcriptional alterations in bone marrow mesenchymal stromal cells derived from acute myeloid leukemia patients We compared the global gene expression profile from AML BM-MSC (n=19) to healthy donor (HD) controls (HD BM-MSC n=4) AML BM-MSC and HD BM-MSC were isolated from bone marrow aspirates (see below) and hybridized on an Affymetrix HG-U133 Plus 2.0 GeneChip
