How well do embryonic stem cells work?Alan HarveyCharles Rodarteentist
Depending on where the stem cells are, they can develop into different tissues. For example, hematopoietic stem cells reside in the bone marrow and can produce all the cells that function in the blood. Stem cells also can become brain cells, heart muscle cells, bone cells or other cell type...
Open pop-up dialog box Stem cells: The body's master cells Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cell...
These daughter cells eitherbecome new stem cells (self-renewal)or becomespecialized cells (differentiation)with a more specific function, such as blood cells, brain cells, heart muscle cells orbone cells. No other cell in the body has the natural ability to generate new cell types. Why is the...
If differentiation of stem cells was simply instructive, it is difficult to imagine how stem cell homeostasis can be maintained in the face of competing demands for one of the stem cell lineages in response to physiological insults. Notably, cell proliferation in the bone marrow must be able to...

Aging impacts diseases and lifespan. With current knowledge of stem cells, it is feasible to design and test interventions that delay aging and improve both health and lifespan. Stem cells, together with anti-aging genes such as Klotho, play a crucial ro
Bone marrow transplants of hematopoietic stem cells have become standard treatment for a host of conditions including cancers of the blood and lymphatic systems, sickle cell anemia, inherited metabolic disorders, and radiation damage. Unfortunately, many
