A clinical research trial of a new treatment to restore brain cells damaged by stroke has passed an important safety stage, according to the UC Irvine neurologist who led the effort. Dr. Steven C. Cramer said patients showed no ill effects after the sequential administration of growth factors encouraging the creation of neurons in stroke-damaged areas of the […]

A mathematical model developed at Purdue University can predict complex signaling patterns that could help scientists determine how stem cells in an embryo later become specific tissues, knowledge that could be used to understand and treat developmental disorders and some diseases. During embryonic development, proteins attach to cell receptors and start a c […]

Chimerix, Inc., a biotechnology company developing orally-available antiviral therapeutics, announced the initiation of a multi-center Phase 2 clinical trial designed to evaluate CMX001 in stem cell transplant recipients who are seropositive for cytomegalovirus (CMV). CMX001 is a broad-spectrum antiviral agent with demonstrated activity against double-strand […]

Immune cells use a bungee-like nanotube to snare dangerous cells, according to new research funded by the Medical Research Council (MRC). The findings by researchers from Imperial College London show that natural killer (NK) cells use this bungee, called a membrane nanotube, to destroy cells that could otherwise escape them... […]

They are considered to be the most important model organism for research into human biology: mice may look totally different, but they are in many ways similar to Homo sapiens on a fundamental level. For instance, an impressive 99 per cent of the mouse genes are matched by a corresponding sequence in the human genome... […]

Seaweed extract may eventually emerge as a lymphoma treatment, according to laboratory research. Seaweeds containing fucoidan, a sulfated polysaccharide similar to heparin in chemical structure, have been reported to have anti-tumor activity in mice and some cell lines. […]

Researchers are the first to fully characterize a special type of stem cell, endothelial progenitor cells (EPCs) that exist in circulating blood, to see if they can behave as endothelial cells in the body when cultured on a bioengineered surface. […]

Researchers Characterize Stem Cell FunctionFriday, 12 March 2010The promise of stem cells lies in their unique ability to differentiate into a multitude of different types of cells. But in order to determine how to use stem cells for new therapeutics, scientists and engineers need to answer a fundamental question: if a stem cell changes to look like a certai […]

Landmark study is first to look at genome of all family membersThursday, 11 March 2010Researchers at the University of Utah Health Sciences and other institutions have sequenced for the first time the entire genome of a family, enabling them to accurately estimate the average rate at which parents pass genetic mutations to their offspring and also identify p […]

New Mechanism Regulating Embryonic Development DiscoveredWednesday, 10 March 2010A Princeton University-led research team has discovered that protein competition over an important enzyme provides a mechanism to integrate different signals that direct early embryonic development. The work suggests that these signals are combined long before they interact with […]

Stem cells of humans and mice differ more strongly than scientists had suspected. New study calls research factors into questionTuesday, 09 March 2010For years, scientists have puzzled over to what extent the findings of studies on the embryonic stem cells (ES cells) of mice are transferable to humans. It is certainly true that human and mouse ES cells are b […]

Theory of Single Stem Cell for Blood Components ChallengedThursday, 04 March 2010Components of the blood or hematopoietic system derive from stem cell subtypes rather than one single stem cell that gives rise to all the different kinds of blood cells equally, said scientists from Baylor College of Medicine in a report that appears in the current issue of the […]
