Noun1.stem cell- an undifferentiated cell whose daughter cells may differentiate into other cell types (such as blood cells) somatic cell,vegetative cell- any of the cells of a plant or animal except the reproductive cells; a cell that does not participate in the production of gametes; "somat...
What makes it so controversial is that the best source of stems cells is the early embryo, and this raises the hackles of pro-lifers who see using embryonic cells as destroying life (embryos). Actually, this is not a valid argument since the embryos used as a source of embryonic stem ...
Stem cell research has been one of the most controversial issues facing Congress since President Bush imposed limits on its financing in 2001. That's because embryonic stem cells come from frozen embryos, the result of in vitro fertilizations, and not everyone agrees on what should be done with...
The main issues include controversy over moral status of embryos and protection of rights for embryo donors. This paper discusses the two major controversial issues arising in biomedical studies of stem cells, explores the directions and approaches to solve some of these issues and introduces the ...
and the security issues among them. In this essay, I will explore the researcher’s trials, experiments processes and results, , acquiring stem cells from adults, and the biology-based problems Maienschein offered. We should continue the study of embryonic stem cell and compare it with iPSC to...
Stem Cell Research essays Scientists have been injecting cells into the spinal cords of monkeys who have Lou Gehrig's- like disease. The point of this new experiment is to find out if stem cells in human embryos and fetuses can regrow healthy neutrons. I

stem cells. These cells are unspecialized and can morph and perform any task that is needed within the body. However, the way that stem cells are harvested has caused a lot of controversy. The way that the stem cells are taken destroys the embryo. We should support the recent decision to...
The potential of stem cell therapies has long been recognised and the creation of induced pluripotent stem cells (iPSC) has boosted the stem cell field leading to increasing development and scientific knowledge. Despite the clinical potential of stem cell based medicinal products there are also ...

Outside these well-documented adult neurogenic regions, the presence of NS cells is more controversial; however,...
