Hemangiomas -- strawberry-like birthmarks that commonly develop in early infancy -- are generally harmless, but up to 10 percent cause tissue distortion or destruction and sometimes obstruction of vision or breathing. Since the 1960s, problematic hemangiomas have been treated with corticosteroids such as dexamethasone or prednisone... […]
University of Chicago scientists have successfully used geometrically patterned surfaces to influence the development of stem cells. The new approach is a departure from that of many stem-cell biologists, who focus instead on uncovering the role of proteins in controlling the fate of stem cells. "The cells are seeing the same soluble proteins... […]
A team of North American collaborators from both industrial research centers (Biotime Inc, Mandala Biosciences LLC and Sierra Sciences LLC) and academic institutes (Ontario Cancer Institute, Burnham Institute for Medical Research and The Scripps Research Institute) have demonstrated successful reversal of the developmental aging of normal human cells...

UroToday.com - Adult tissue regeneration or remodeling is suggested to initiate from multipotent stem and/or progenitor cells. We recently reported two new human adult non-tumorigenic prostatic epithelial cell lines NHPrE1 and BHPrE1, which were generated and characterized in our laboratory... […]
Researchers have identified a key cellular mechanism that guides embryonic heart tissue formation -- a process which, if disrupted, can lead to a number of common congenital heart defects. […]
Bone marrow stem cells suspended in X-ray-visible microbubbles dramatically improve the body's ability to build new blood vessels in the upper leg -- providing a potential future treatment for those with peripheral arterial disease or PAD, say researchers. […]

Researchers have found that one particularly aggressive type of blood cancer, mixed lineage leukemia, has an unusual way to keep the molecular motors running. The cancer cells rely on the normal version of an associated protein to stay alive. […]
Researchers recently discovered that infantile hemangiomas originate from stem cells, and have used these stem cells to better understand this tumor in the laboratory. They show that steroids target hemangioma stem cells specifically, reveal their mechanism of their action and suggest other possible ways to halt and shrink hemangiomas. […]

Cell of Cells: The Global Race to Capture and Control the Stem Cell
A petition protesting against Pope Benedict XVI's visit to Britain later this year is to be handed in to Downing Street by the National Secular Society. […]
Not genes so much as surrounding sequences, says Stanford study Thursday, 18 March 2010 The key to human individuality may lie not in our genes, but in the sequences that surround and control them, according to new research by scientists at the Stanford University Medical Center and Yale University. The interaction of those sequences with a class of key prot […]
Findings based on analysis of largest set of genetic markers ever studied Thursday, 18 March 2010 Dogs likely originated in the Middle East, not Asia or Europe, according to a new genetic analysis by an international team of scientists led by UCLA biologists. The research, funded by the National Science Foundation and the Searle Scholars Program, appears Mar […]
Wistar scientists demonstrate mammalian regeneration through a single gene deletionTuesday, 16 March 2010A quest that began over a decade ago with a chance observation has reached a milestone: the identification of a gene that may regulate regeneration in mammals. The absence of this single gene, called p21, confers a healing potential in mice long thought t […]
Amniotic Fluid Cells More Efficiently Reprogrammed to Pluripotency than Adult CellsTuesday, 16 March 2010Researchers at Mount Sinai School of Medicine have demonstrated that skin cells found in human amniotic fluid can be efficiently "reprogrammed" to pluripotency, where they have characteristics similar to human embryonic stem cells that can devel […]
