Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.

Project description:MSCs comprise several percent of pluripotent-like cells named Multilineage-differentiating stress enduring (Muse) cells that express pluripotent markers at moderate levels, are collectable as cells positive for the pluripotent surface marker SSEA-3, are able to differentiate into triploblastic lineage cells, and self-renew at the single cell level (Kuroda et al, PNAS, 2010; Wakao et al, PNAS, 2011). Importantly, MSCs also comprise cells other than SSEA-3(+)-Muse cells, namely multipotent SSEA-3(-)-non-Muse MSCs that correspond to ~98% of the total MSC population. These SSEA-3(-)-non-Muse MSCs exhibit the same properties as conventional MSCs, although the non-Muse MSCs are multipotent, they are not pluripotent. In the present study, to clarify the key molecules that characterize pluripotent-like vs multipotent somatic stem cells, we separated human MSCs into SSEA-3(+)-Muse cells and SSEA-3(-)-non Muse MSCs, and analyzed both populations by scRNA-seq. SSEA-3(+) Muse cells and SSEA-3(-) non-Muse MSCs were sorted from human BM-MSCs. Sequencing libraries were prepared using Chromium single cell 3' Kit v3 (10x Genomics, Pleasanton, CA, USA) and sequenced on HiSeq2500 (Illumina, San Diego, CA, USA). Transcripts were mapped with CellRanger pipeline v3 (10x Genomics). Library construction, sequencing, and initial analysis were performed by GENEWIZ (South Plainfield, NJ, USA).

Project description:Microarray analysis of the gene expression profile of SSEA-3-positive human adipose-derived MSCs were performed. Liposuction aspirates were obtained from the abdomen and thighs. Stromal vascular fraction (SVF) was isolated from the aspirated fat. Muse cells that express human SSEA-3 were collected from SVF using anti SSEA-3 antibody conjugated with PE and anti-PE microbeads. SSEA-3-negative fraction was considered M-bM-^@M-^XMuse-poor populationM-bM-^@M-^Y.
