The work presented in this poster covers the investigation of key parameters for the expansion of stem cells in an automated micro-well format. The effect of inoculation seeding density (ICD), well size, passage number and feeding strategies on the proliferation of human mesenchymal stromal cells (hMSC) was investigated. In parallel the effect of well size and seeding density on the proliferation of mouse embryonic stem (mES) cells was also examined. The studies represent the first steps in defining critical parameters for the automation of stem cell cultures.
We found a distinct subpopulation of Tregs within BMSCs. Tregs and BMSCs in co-culture conferred neuroprotection that varied in a dose-dependent manner. Tregs minimized stem cell production of IL-6, a pro-inflammatory cytokine, and inhibited BMSC secretion of FGF-beta, a cytokine related to BMSC proliferation and differentiation. The ratio of Tregs found natively in BMSCs is optimally adapted to provide the maximum neuroprotective benefit of stem cell treatment after ischemic stroke.READ MORE
