Scientists convert skin cells to beating heart cells
Scripps Research Institute scientists have converted adult skin cells directly into beating heart cells efficiently without having to first go through the laborious process of generating embryonic-like stem cells. The powerful ...
World's first chimeric monkeys are born
Researchers have produced the world's first chimeric monkeys. The bodies of these monkeys, which are normal and healthy, are composed of a mixture of cells representing as many as six distinct genomes. The ...
Study of skates and sharks questions assumptions about 'essential' genes
Biologists have long assumed that all jawed vertebrates possess a full complement of nearly identical genes for critical aspects of their development. But a paper in the December 16 issue of Science with Benjamin King of the ...
Personalised stem cells back in the spotlight
Scientists on Wednesday said they had made strides in lab research in personalised stem cells, reviving interest in a goal clouded by fraud and ethical storms.
Embryo development obeys the laws of hydrodynamics
Vincent Fleury, a researcher at the Paris Diderot University, studied the early stage of development when embryonic cells first form a flat sheet of cells before folding into a U-shape, resembling a folded ...
Cancer researchers link DICER1 gene mutation to rare childhood cancer
Research published today in Science Express from the journal Science demonstrates the first definitive link between mutations in the gene DICER1 and cancer. By studying the patterns of DNA from 11 families with an unusua ...
Early exposure to insecticides gives amphibians higher tolerance later
Amphibians exposed to insecticides early in life—even those not yet hatched—have a higher tolerance to those same insecticides later in life, according to a recent University of Pittsburgh study.
Rewinding development: A step forward for stem cell research
Scientists at the Danish Stem Cell Center, DanStem, at the University of Copenhagen have discovered that they can make embryonic stem cells regress to a stage of development where they are able to make placenta ...
Stem cells develop best in 3-D
Scientists from The Danish Stem Cell Center (DanStem) at the University of Copenhagen are contributing important knowledge about how stem cells develop best into insulin-producing cells. In the long term this new knowledge ...
A new shortcut for stem cell programming
Scientists at the Life and Brain Research Center at the University of Bonn, Germany, have succeeded in directly generating brain stem cells from the connective tissue cells of mice.
Neutralizing tumor growth in embryonic stem cell therapy
Researchers at the Hebrew University of Jerusalem have discovered a method to potentially eliminate the tumor-risk factor in utilizing human embryonic stem cells.
'Sister' factors promote survival of blood-system stem cells
Stem cells of any kind are defined by their eternal nature, reproducing themselves and providing a pool of cells from which more differentiated tissues arise.
