	Pluripotential hemopoietic stem cell Information
		PHSC are the precursor cells which give rise to all the blood cell types of both the myeloid and lymphoid lineages.
		PHSC are found in the bone marrow of adults, which includes femurs, hip, ribs, sternum, and other bones.
		Cells can be obtained directly by removal from the hip using a needle and syringe, or from the blood following pre-treatment with cytokines that induce cells to be released from the bone marrow compartment.

	Type of Stem Cell
		The fact that stem cells may be derived from living embryos that are destroyed in the process or from aborted fetuses ties the discussion of stem cell research to the ongoing debates on abortion.
		Yeast cell size regulation in mammals The protein mTOR is a serine/threonine kinase that regulates translation and cell division before reaching the normal cellular amount of DNA may not be adequate to keep the cell surface membrane in order to increase the surface area available for transport functions.
		Sertoli cells assist in the production of sperm in the context of reproduction of living cells the phrase "cell growth" refers to increases in cell size regulation The relationship between cell divisions is increased.

		Megakaryocytes account for less than 1% of bone marrow cells but can be 10 to 15 times larger than a typical red blood cell.(Compare to other cells) DNA synthesis is occurring in the nucleus during thrombopoiesis (stimulated by thrombopoietin) without cytokenesis, aka endoreduplication.
		The cell may release its platelets by rupturing and releasing its contents all at once in the marrow.
		The developmental stages of the megakaryocyte is: CFU-Me (pluripotential hemopoietic stem cell or hemocytoblast) -> megakaryoblast -> promegakaryocyte -> megakaryocyte.

	The Scientist : A Paradigm Shift in Stem Cell Research? (Site not responding. Last check: 2007-10-24)
		Stem cell research is upsetting the long-held view that in animal embryogenesis, position is everything.
		These hematopoietic stem cells were more prevalent in brain than blood, which Bartlett thought argued against their having arrived in the brain from the bone marrow during embryogenesis, before the blood-brain barrier could block entry.
		Another is that stem cells are there for a purpose, to produce more of what's there, but under different conditions they can be reprogrammed to differentiate in another direction." The origin answer will come, both agree, from efforts to isolate and characterize the similarities and differences among many stem cell types.

	2. The Embryonic Stem Cell [Stem Cell Information]
		Studies of ES cells derived from mouse blastocysts became possible 20 years ago with the discovery of techniques that allowed the cells to be grown in the laboratory.
		These cells proliferate extensively in the embryo, are capable of differentiating into all the types of cells that occur in the adult, and can be isolated and grown ex vivo (outside the organism), where they continue to replicate and show the potential to differentiate [18].
		Chimeras are a mixture of tissues and organs of cells derived from both donor ES cells and the recipient blastocyst.

	Pluripotential hemopoietic stem cell \| English \| Dictionary & Translation by Babylon
		Hematopoietic stem cells (HSC) are stem cells found in the bone marrow.
		HSC are the precursor cells which give rise to all the types of both the myeloid and lymphoid lineages.
		As stem cells, they are defined by their ability to form multiple cell types (multipotency) and their ability to self-renew.

	Pluripotential hemopoietic stem cell - Wikipedia, the free encyclopedia
		Self-Renewal: Some kinds of stem cells are thought to undertake asymmetric cell division, generating one daughter cell that remains a stem cell and one daughter cell that differentiates.
		Stem cell self-renewal is thought to occur in the stem cell niche in the bone marrow, and it is reasonable to assume that key signals present in this niche will be important in self-renewal.
		Cells can be obtained directly by removal from the hip using a needle and syringe, or from the blood following pre-treatment with cytokines, such as G-CSF (granulocyte colony stimulating factors), that induce cells to be released from the bone marrow compartment.

		Stem cell line - A stem cell line is a family of constantly dividing cells, the product of a single embryo.
		All plant cells are totipotent not just under the right conditions, such as basic cell biology, molecular biology and hematology, and the proliferation of clinical studies involving stem cell research is gradually crossing over into the practice of medicine as many patients may become candidates for such novel treatments.

		Failure of regulatory T cells to function properly may result in autoimmune diseases in which the immunocytes attack healthy cells in the body.
		Throughout their existence, T cells recognize only those antigens, for which they are specific and that are bound in a complex with the MHC molecule of the type they were presented with in the thymic cortex.
		The cells that survive positive selection move towards the thymic medulla where at the boundary between thymic cortex and thymic medulla and in the medulla, they are presented with self-antigens in a complex with MHC molecules on the surface of type V and VI thymic epithelioreticular cells, as well as dendritic cells.

	Jill Stanek - Stem cell archives
		Ortiz, who chairs the subcommittee overseeing the stem cell project, said her fellow legislators are unlikely to support wholesale adoption of the proposed policy.
		Because most embryonic stem cell research today is being performed by the private sector (without NIH federal funding), there is today a lack of ethical and scientific oversight that routinely accompanies NIH-(federal) funded research.
		If you oppose stem cell research, because of religious beliefs, or because you think it takes life, or because you are not sure embryo cells are that much superior to umbilical cord cells in doing stem cell research, or that this might be going down a slippery slope, you're irrelevant.

	Regulatory T cell - Enpsychlopedia
		Regulatory T cells (also known as suppressor T cells) are a specialized subpopulation of T cells that act to suppress activation of the immune system and thereby maintain immune system homeostasis and tolerance to self.
		The existence of a dedicated population of “suppressor” T cells was the subject of significant controversy among immunologists for many years.
		Interest in regulatory T cells has been heightened by evidence from experimental mouse models demonstrating that the immunosuppressive potential of these cells can be harnessed therapeutically to treat autoimmune diseases and facilitate transplantation tolerance or specifically eliminated to potentiate cancer immunotherapy.
