Three-Dimensional Cell Culture Within A Biomimetic Hydrogel Based On Chitosan And Hyaluronan
Poster Mar 23, 2010
A growing demand for study of cells within biologically realistic, in vitro, microenvironments requires a paradigm shift in cell culture technology: from cell culture on 2-D, rigid substrata to cell growth within a 3-D space, defined by malleable materials composed of biologically “smart” compounds.1, 2
Therapeutic issues addressed by tissue engineering and regenerative medicine require similar materials, customized for human application in a wide variety of treatment circumstances: ranging from the ideal operating room to battle field conditions.
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
