scientists successfully expand bone marrow-derived stem cells in culture | Stowers Institute for Medical Research scientists successfully expand bone marrow-derived stem cells in culture | Stowers Institute for Medical Research KANSAS CITY, MO—All stem cells—regardless of their source—share the remarkable capability to replenish themselves by undergoing self-renewal. Yet, so far, efforts to grow and expand scarce hematopoietic (or blood-forming) stem cells in culture for therapeutic applications have been met with limited success. Now, researchers at the Stowers Institute for Medical Research teased apart the molecular mechanisms enabling stem cell renewal in hematopoietic stem cells isolated from mice and successfully applied their insight to expand cultured hematopoietic stem cells a hundredfold. Their findings, which will be published in the Sept. 15, 2011, edition of Genes & Development, demonstrate that self-renewal requires three complementary events: proliferation, active suppression of differentiation and programmed cell death during proliferation.
Pigs could grow human organs in stem cell breakthrough Professor Hiromitsu Nakauchi, director of the centre for stem cell biology and regenerative medicine at the University of Tokyo in Japan and who led the research, said: "Our ultimate goal is to generate human organs from induced pluripotent stem cells. "The technique, called blastocyst complementation, provides us with a novel approach for organ supply. We have successfully tried it between mice and rats. We are now rather confident in generating functional human organs using this approach." Pigs could grow human organs in stem cell breakthrough

What are the unique properties of all stem cells? Stem cells differ from other kinds of cells in the body. All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types. Stem cells are unspecialized. One of the fundamental properties of a stem cell is that it does not have any tissue-specific structures that allow it to perform specialized functions. For example, a stem cell cannot work with its neighbors to pump blood through the body (like a heart muscle cell), and it cannot carry oxygen molecules through the bloodstream (like a red blood cell).

The Neural Stem Cell Institute (NSCI) is dedicated to developing regenerative stem cell therapies for various diseases of the central nervous system (CNS): the brain, spinal cord and retina, regardless of the cause of injury. Led by MacArthur “Genius” Award winner Dr. Sally Temple who helped discover and define nervous system stem cells, NSCI is the first independent, non-profit stem cell research institute in the USA. - Neural Stem Cell Institute - Neural Stem Cell Institute
