Affymetrix CytoScan 750K array data for a parthenogenetic SMA human embryonic stem cell line

ABSTRACT: A diploid 46(XX) human embryonic stem cell (HESC) line affected by Spinal muscular atrophy type 1 (SMA) due to homozygosity for a common deletion in the SMN1 gene was derived. By characterizing the methylation status of three different imprinted loci (MEST, SNRPN and H19) and carrying out genome-wide SNP analysis, we provide evidence that this cell line was established from the activation of a mutant haploid oocyte through parthenogenesis, resulting in homozygote diploidization of the entire genome. Affymetrix CytoScan 750K array analysis was performed according to the manufacturer's directions on DNA extracted from tissue culture. Copy number and LOH analysis of the Affymetrix CytoScan 750K array was performed for the SMA HESC line.

Affymetrix SNP array data for myelodysplastic syndromes (MDS) samples

Project description:The progressive mechanism of myelodysplastic syndrome (MDS) remains unknown. We report that ROBO1 and ROBO2 are identified as novel progression-related somatic mutations using whole-exome and targeted sequencing in six of 16 (37.5%) paired MDS patients undergoing disease progression. To investigated the effect of ROBO1 or ROBO2 on ROBO1/2 CN number and LOH, we employed a Cytosan 750K chip to analyze the copy-number variations (CNVs) and loss of heterogeneity (LOH) in MDS patients with ROBO1&2 mutations. Copy number and LOH analysis of Affymetrix CytoScan 750K array was performed for 14 MDS patients with ROBO1 or ROBO2 mutations

Analysis of the protein cargo of extracellular vesicles isolated from cultured line H9 human stem cells

Project description:Extracellular vesicles (EV) are secreted by nearly every mammalian cell type and contain a wealth of bioactive cargo capable of modulating target cell physiology and function though a variety of paracrine signaling mechanisms (Leavitt et al., 2019). Human embryonic stem cell (hESC)-derived extracellular vesicles (hESC-derived EV), were extracted from the hESC line H9 (WA09 Wicell Research Institute, Inc., Madison, WI). We analyzed the bioactive protein cargo to identify components that help to resolve radiation-induced injury to the lung in mice when injected in vivo.
