There are, however, two ways for the federal government to aggressively promote stem cell research without inviting ethical abuses.
Morrison, S. J. & Spradling, A. C. Stem cells and niches: mechanisms that promote stem cell maintenance throughout life.
van den Beucken, T. et al. Hypoxia promotes stem cell phenotypes and poor prognosis through epigenetic regulation of DICER.
The hypoxia-associated factor switches cells from HIF-1a- to HIF-2a-dependent signaling promoting stem cell characteristics, aggressive tumor growth and invasion.
Developing biomaterials to promote stem cell proliferation and differentiation is a critical requirement in tissue engineering and regeneration.
By undergoing conjugation with various proteins, GAGs play important roles in a variety of bioactivities, including promoting stem cell differentiation.
CONCLUSIONS: Wnt signaling activates genes that promote stem cell fate and inhibit cellular differentiation and regulates a remarkable number of genes involved in its own signaling system.
WASHINGTON, Oct. 4 Â Amid hints that the race has tightened, President Bush and Senator John Kerry campaigned in battleground states today on domestic issues, with Mr. Bush extolling his tax policies and Mr. Kerry promoting stem cell research.
One independent, Rick Snyder, 47, a pharmacist in Northampton, Pa., who voted for Mr. Bush in 2000, said that he had a friend with Parkinson's disease and that he favored Mr. Kerry because the senator would promote stem cell research.
The team realized that in order to get mice to produce those humanized cells, they would have to express human cytokines that promote stem cell differentiation into NK cells and myeloid cells such as macrophages.
