Embryonic vs adult stem cells
When a stem cell divides, each new cell has the potential either to remain a stem cell or become another a more specialized cell type, such as a muscle cell, a red blood cell, or a brain cell Fig 1. National Institutes of Health, U. Third, tissue rejection problems similar to those encountered in kidney and heart transplants may limit the usefulness of fetal stem cells. Hodgkin's lymphoma Hodgkin's disease Hodgkin's vs. Doctors have performed stem cell transplants, also known as bone marrow transplants.
Stem cells: What they are and what they do
By contrast, adult islet cell transplants have already allowed hundreds of juvenile diabetes patients to throw away their insulin needles, and even newer approaches, which do NOT use embryonic stem cells may be in human trials soon. This may make them more useful in understanding how diseases develop. Contact staff writer Bradley J. Journal of Cardiovascular Development and Disease. A precious cell source for clinical applications.
Where Do We Get Adult Stem Cells? | Boston Children's Hospital
Both of these research types are very similar, but there are also differences between the two that make one research type more beneficial in certain situations. Contact staff writer Bradley J. Therapies in Development - Motor Symptoms. It isn't just religious people who have ethical concerns about harvesting cells from embryos and the ethical implications of such practices have not been honestly debated or given the gravitas that experimenting on nascenthuman life should have raised. These embryonic stem cells are pluripotent , meaning that they can turn into more than one type of cell.
Both induced pluripotent cells and embryonic stem cells can help us understand how specialized cells develop from pluripotent cells. Identification of PGC7, a new gene expressed specifically in preimplantation embryos and germ cells. To create iPSCs, scientists genetically reprogram the adult stem cells so they behave like embryonic stem cells. These cells may have potential both for cell replacement treatment approaches in patients and as disease models that scientists could use in screening new drugs. Researchers have discovered ways to direct stem cells to become specific types of cells, such as directing embryonic stem cells to become heart cells.
