Regulation of shoot apical meristem development by SEUSS and SEUSS-LIKE 2 in Arabidopsis

Joanne E. Lee and John F. Golz
In Arabidopsis, SEU and SLK2 are redundant components of a regulatory complex that is proposed to promote shoot apical meristem (SAM) formation during embryogenesis. Expression analysis indicates that SEU and SLK2 act upstream of several known SAM regulators, and also regulate auxin accumulation, probably via interaction with auxin response factors. Future work will be aimed at identifying direct targets of regulation and further investigating downstream components of the SAM-promoting pathway.
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
