Creation Of Heart And Blood Cells From Reprogrammed Skin CellsStem cell researchers at UCLA were able to grow functioning cardiac cells using mouse skin cells that had been reprogrammed into cells with the same unlimited properties as embryonic stem cells.The finding is the first to show that induced pluripotent stem cells or iPS cells, which don't involve the use of embryos or eggs, can be differentiated into the three types of cardiovascular cells needed to repair the heart and blood vessels.Mouse Adult Stem Cells Developed Into Heart And Blood CellsResearchers have succeeded in inducing stem cells grown from mouse skin cells to differentiate into functioning cardiovascular and blood cells, according to a study publishing online tomorrow in the journal "Stem Cells." "Induced pluripotent stem (iPS) cells are reprogrammed cells obtained by genetic manipulation of normal adult cells that then express capabilities similar to embryonic stem cells," explains Dr. Miodrag Stojkovic, Co-Editor of "Stem Cells.Eradicating Breast Cancer By Attacking The RootsThe lesson learned in eradicating dandelions from your yard could apply in treating breast cancer as well, said researchers from Baylor College of Medicine in Houston in a report that appears online in the Journal of the National Cancer Institute."It's not enough to kill the dandelion blossom and stalk that appear above ground," said Dr.Discovery Of Stem Cells In The Pituitary Gland Of Mice Suggests A Means Of Adapting To Stress And Life ChangesA team of researchers led by scientists at Cold Spring Harbor Laboratory have for the first time identified stem cells that allow the pituitary glands of mice to grow even after birth. They found that, in contrast to most adult stem cells, these cells are distinct from those that fuel the initial growth of this important organ.Menstrual Blood Shows Heart Repairing Stem Cell PropertiesScientists in Japan have discovered that cells taken from menstrual blood can be cultivated in the lab and used like stem cells to repair damaged heart tissue.The initial results of the work were published last week in the journal Stem Cells.VistaGen Collaborates With Canadian, U.S., And British Researchers To Isolate Earliest Embryonic Stem Cell-Derived Human Cardiac CellJoined by scientists from VistaGen Therapeutics here, a team of leading Canadian, American and British medical researchers have used embryonic stem (ES) cells differentiation cultures to successfully identify, grow and study the earliest cell destined to form the human heart. This novel cardiac stem cell is able to produce all three types of cells important to the cardiovascular system.Fly Lifespan Lengthened By Eliminating GermlineNew research by Brown University biologists shows that fruit flies live longer when they don't produce germline stem cells - the cells that create eggs and sperm.The work suggests a provocative general principle at work: Signals from reproductive tissue directly control lifespan and metabolism in the whole organism.
