Sperm stem cells closer to being like embryonic stem cells
New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body.   view more (2005-11-16)

Researchers devise new technique for creating human stem cells
Researchers have developed a new technique for creating human embryonic stem cells by fusing adult somatic cells with embryonic stem cells.   view more (2005-08-23)

University of Pennsylvania Researchers Discover "Killer" B Cells; New Link in the Evolution of Immunity
Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered a unique evolutionary link between the immune systems of fish and mammals in the form of a primitive version of B cells, white blood cells of the immune system.   view more (2006-09-21)

A novel mechanism of action for anti-tumor agent, CA4P
Anti-angiogenic agents have been successful in the clinic for blocking the growth of solid tumors. However, these agents used in combination with chemotherapy have improved the survival of patients with cancers by only several months.   view more (2005-10-07)

MicroRNA may have fail-safe role in limb development
A tiny strand of molecules plays a role in how our arms and legs develop and grow-a finding that sheds light on perplexing bits of material once dismissed as genetic "junk," say scientists at the University of Florida and Harvard University.   view more (2005-12-02)

Scientists develope a new model of artificial canine skin
Researchers at UNIVET, a spin-off of the Universitat Autònoma de Barcelona, in cooperation with the animal nutrition company Affinity Petcare, have developed an artificial cellular model which faithfully reproduces the characteristics of dog's skin and which will allow, therefore, the... view more (2007-05-11)

First Parkinson's Gene Therapy Patient Passes One Year
The first ever patient to have undergone gene therapy for Parkinson's appears to have come through phase I without a hitch, suggesting that the therapy is safe and effective, reports Marina Murphy in Chemistry & Industry.   view more (2004-09-02)

Genetics of muscular dystophy
Various forms of human muscular dystrophy result from mutations in genes encoding proteins of the nuclear envelope. A new paper in the February 15th issue of G&D reveals how.   view more (2006-02-15)

Cancer stem cells spur glioma Angiogenesis, could hold key to brain tumor therapy
Stem cell-like glioma cancer cells that share many characteristics with normal stem cells propel the lethal growth of brain cancers by promoting tumor blood vessel formation, and may hold the key to treating these deadly cancers.   view more (2006-08-15)

Making memories that last a lifetime
Neurobiologists have discovered a mechanism by which the constantly changing brain retains memories—from that dog bite to that first kiss. They have found that the brain co-opts the same machinery by which cells stably alter their genes to specialize during embryonic development.   view more (2007-03-15)

Silenced gene in worm shows role in regeneration
Researchers at the University of Utah have discovered that when a gene called smedwi-2 is silenced in the adult stem cells of planarians, the quarter-inch long worm is unable to carry out a biological process that has mystified scientists for centuries: regeneration.   view more (2005-11-28)

UCLA researchers discover new disorder that causes chronic diarrhea in children
UCLA researchers have unraveled a mysterious condition that causes congenital diarrhea and intestinal failure in children.   view more (2006-07-20)

Stem cells as cancer therapy
It is widely hoped that neural stem cells will eventually be useful for replacing nerves damaged by degenerative diseases like Alzheimer disease and multiple sclerosis. But there may also be another use for such stem cells-delivering anti-cancer drugs to cancer cells.   view more (2006-12-26)

The difference between fish and humans: scientists answer century-old developmental question
Embryologists at UCL (University College London) have helped solve an evolutionary riddle that has been puzzling scientists for over a century.   view more (2007-10-11)

How does a zebrafish grow a new tail?
If a zebrafish loses a chunk of its tail fin, it'll grow back within a week. Like lizards, newts, and frogs, a zebrafish can replace surprisingly complex body parts. A tail fin, for example, has many different types of cells and is a very intricate structure. It is the fish version of an arm or leg.   view more (2006-12-27)

Factor stimulates cartilage growth from stem cells
A novel growth factor significantly improves the ability of specialized stem cells derived from human fat to be transformed into cartilage cells, according to Duke University Medical Center and Pratt School of Engineering researchers.   view more (2006-04-05)

Adult human neural stem cell therapy successful in treating spinal cord injury
Researchers at the UC Irvine Reeve-Irvine Research Center have used adult human neural stem cells to successfully regenerate damaged spinal cord tissue and improve mobility in mice.   view more (2005-09-20)

Knowledge of dendritic cells branches out
Dendritic cells (or "DC" ) are specialised white blood cells that patrol the body, searching for infections.   view more (2006-05-09)

Newfound roadblock to interferon effectiveness against malignant melanoma
Researchers have uncovered a significant contributing factor to interferon resistance of malignant melanoma cells.   view more (2005-09-22)

New genetic model for Parkinson's disease
Researchers at the Karolinska Institute in Sweden are homing in on mechanisms that may explain one set of causes for Parkinson's disease.   view more (2006-07-28)

Inhibiting cell process may give cancer drug a boost
A molecule that interferes with the internal scaffolding that shapes the cell may kill cancer cells, retard the growth of tumors and give a boost to a common chemotherapy drug.   view more (2006-05-04)

Targeted drug delivery now possible with 'pHLIP' peptide
Scientists at Yale and the University of Rhode Island report the development of a peptide that can specifically and directly deliver molecules to the inside of cells like a nanosyringe, creating a new tool for drug delivery, gene control and imaging of diseased tissues.   view more (2006-04-12)

Copper circuits help brain function — could tweaking the circuits make us smarter?
The flow of copper in the brain has a previously unrecognized role in cell death, learning and memory.   view more (2006-09-26)

New clues for treatment of liver cancer
By generating tumors in laboratory mice that mimic human liver cancer and by comparing the DNA of mouse and human tumors, researchers at Cold Spring Harbor Laboratory have identified two genes that are likely to play a role in the third leading cause of human cancer deaths.   view more (2006-06-29)

Liver Cancer Linked to Cellular Repair Pathway
The unchecked activity of a cell signaling pathway crucial in embryonic development and the liver's response to injury leads to liver cancer.   view more (2006-03-30)
