(Ivanhoe Newswire) -- A team of researchers has now compared the ability of cells derived from different types of human stem cell to reverse disease in a rat model of Parkinson's disease and identified a stem cell population that they believe could be clinically relevant. Parkinson disease results from the progressive loss of a specific subpopulation of nerve cells. Current treatments provide only relief from the symptoms of the disease and cannot reverse the nerve cell loss. Stem cells are...

Ever since animals, such as lizards and starfish, were observed regenerating missing body parts, people have wondered where the new tissues come from. In the case of the planarian flatworm, Whitehead Institute researchers have determined that the source of this animal's extraordinary regenerative powers is a single, pluripotent cell type. Most advanced animals, including mammals, have a system of specialized stem cells. In humans, we have blood stem cells in our bone marrow that make blood...

A single adult cell from one of the most impressive masters of regeneration in the animal kingdom "“ the planarian "“ is all it takes to build a completely functional new worm, researchers have learned. The study provides the first hard evidence that adult planarians harbor pluripotent stem cells "“ cells capable of producing the diverse range of tissue types necessary to build a complete animal. Distributed throughout the worm body, the newfound cells appear to have the...

Stem cells are considered by many to be promising candidate sources of cells for therapies to regenerate and repair diseased tissues. There are two types of stem cell considered in this context: embryonic stem (ES) cells, which are derived from early embryos; and induced pluripotent stem (iPS) cells, which are derived by reprogramming cells of the body such that they have the ability to generate any cell type. Recent data indicate that ES and iPS cells are molecularly different, raising the...

Discoveries will advance medicine and human health A scientist at the Gladstone Institutes has made two significant stem-cell discoveries that advance medicine and human health by creating powerful new approaches for using stem cells and stem-cell-like technology. In two papers being published on April 25 in the Proceedings of the National Academy of Sciences, Sheng Ding, PhD, reveals novel and safer methods not only for transforming embryonic stem cells into large numbers of brain cells with...

A paper published by Cell Press in the April 8th issue of the journal Cell Stem Cell reveals a new and more efficient method for reprogramming adult mouse and human cells into an embryonic stem cell-like state and could lead to better strategies for developing stem cells for therapeutic use. The ability to reprogram adult cells into cells that resemble embryonic stem cells has tremendous potential for both stem cell research and regenerative medicine. "Previous studies have demonstrated the...

Move over, newts and salamanders. The mouse may join you as the only animal that can re-grow their own severed limbs. Researchers are reporting that a simple chemical cocktail can coax mouse muscle fibers to become the kinds of cells found in the first stages of a regenerating limb. Their study, the first demonstration that mammal muscle can be turned into the biological raw material for a new limb, appears in the journal ACS Chemical Biology. Darren R. Williams and Da-Woon Jung say their...

Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
