Umbilical cord blood (UCB) has recently been the focus of clinical applications. UCB contains of hematopoietic stem cells and mesenchymal stem cells (MSC). Clinical studies shows that MSC can be used in regenerative medicine hereby treatment of cardiac diseases. The aim of this project is to establish a protocol for isolation of MSCs from frozen UCB. This study demonstrated that it’s possible to expand MSC.
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
