Researchers have unearthed new clues behind a disease that effectively turns young children into senior citizens. A protein called progerin prods stem cells to go astray, causing them to mature into the wrong cell types. The findings may have implications for understanding normal aging as well. 
New brain cells listen before they talk

Newly-created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival -- which has implications for using adult stem cells to replace those lost by trauma or neurodegeneration.

Researchers at the University of Minnesota's Stem Cell Institute have described how an existing genetic tool can be used to study how human embryonic stem cells differentiate. The research appears in the November 2007 issue of Experimental Biology and Medicine.
Blood vessels grown from patient's own tissues used successfully in human patients
Darkfrog submitted, created time 1 year 1 month (www.nytimes.com)
Thirteen months and so far so good. Unlike earlier techniques used in Japan, which involved growing cells on a scaffold that slowly dissolved after implantation, scientists in Argentina grew whole stretches of blood vessel from the patients' own cells. The patients in question have damaged veins and arteries in their arms from regular dialysis.
This does not involve stem cells of any kind. A strip of skin is removed from the patient, but the fibroblast and endothelial cells are taken from the inside of the veins in that strip of skin
Stem cell pioneers scoop Nobel Prize

The Nobel Prize in Physiology or Medicine 2007 has been awarded to two Americans who pioneered ways of "knocking out" specific genes in mice to reveal their function and their impact on disease.

Human colonic epithelial cell renewal, proliferation, and differentiation are stringently controlled by numerous regulatory pathways. To identify genetic programs of human colonic epithelial cell differentiation in vivo as well as candidate marker genes that define colonic epithelial stem/progenitor cells and the stem cell niche, we applied gene expression analysis of normal human colon tops and basal crypts by using expression microarrays with 30,000 genes.
USC researcher identifies stem cells in tendons that regenerate tissue in animal model

A consortium of scientists, led in part by USC School of Dentistry researcher Songtao Shi, has identified unique cells within the adult tendon that have stem-cell characteristics -- including the ability to proliferate and self-renew. The research team was able to isolate these cells and regenerate tendon-like tissue in the animal mode.
Pittsburgh scientists identify human source of stem cells with potential to repair muscle
sumsung submitted, created time 1 year 2 months (www.eurekalert.org)
For the first time, scientists at Children's Hospital of Pittsburgh of UPMC have discovered a unique population of adult stem cells derived from human muscle that could be used to treat muscle injuries and diseases such as heart attack and muscular dystrophy.
Using stem cells to help heart attack victims

New research at The University of Nottingham is paving the way for techniques that use stem cells to repair the damage caused by heart attacks.
A new method of adult stem cell growth efficacious in treatment of disorders of the cornea

A new method of adult stem cell growth, designed in the Area of Cellular Therapy of the University Clinic (University of Navarra), has demonstrated its efficacy for its capacity to grow cornea stem cells.
Cells take risks with their identities
bianjie submitted, created time 1 year 4 months (www.eurekalert.org)
Contrary to textbook models, many genes that should be "off" in embryonic stem cells and specialized adult cells remain primed to produce master regulatory proteins, leaving those cells vulnerable to identity changes. The genes encoding the master regulators of cell fate begin making RNA templates for these proteins, though a control mechanism stops them from finishing the job.
Researchers discover human embryonic stem cells are the ultimate perpetual fuel cell

An article published in the prestigious scientific journal Nature this week reports on a new understanding of the growth of human stem cells.
Engineered blood vessels function like native tissue
bianjie submitted, created time 1 year 4 months (www.buffalo.edu)
Blood vessels that have been tissue-engineered from bone marrow adult stem cells may in the future serve as a patient's own source of new blood vessels following a coronary bypass or other procedures that require vessel replacement, according to new research from the University at Buffalo Department of Chemical and Biological Engineering.
Stem cell procedure successfully treats amyloidosis patients
bianjie submitted, created time 1 year 4 months (www.eurekalert.org)
Researchers from the Stem Cell Transplant Program and the Amyloid Treatment and Research Program at Boston University Medical Center (BUMC) have found that tandem cycles of high-dose chemotherapy and blood stem cell transplantation can help treat patients with immunoglobulin-light chain (AL) Amyloidosis who did not respond to initial treatment with this method.
The New Question: What to Do with Those Rescued Embryos?
