Male Fertility Relies On A Key Protein That Also Protects Against Disease
2014-05-13 10:58:14

Brett Smith for redOrbit.com - Your Universe Online Male infertility prevents many couples from being able to conceive a child and a new study published in the journal Nature Communications has found a specific protein that is a major determining factor in determining a sperm’s ability to fertilize an egg. The protein, known as Chd5, is responsible for effectively packaging DNA inside the head of a sperm, where space it at a premium. Each cell in the body contains an entire copy of...

Salk scientists find two key proteins that regulate the growth of mammary stem cells and could contribute to breast cancer By carefully controlling the levels of two proteins, researchers at the Salk Institute have discovered how to keep mammary stem cells—those that can form breast tissue—alive and functioning in the lab. The new ability to propagate mammary stem cells is allowing them to study both breast development and the formation of breast cancers. "What we've shown is that...

Findings and Significance: During breast-tissue development, a transcription factor called SLUG plays a role in regulating stem cell function and determines whether breast cells will mature into luminal or basal cells. Studying factors, such as SLUG, that regulate stem-cell activity and breast-cell identity are important for understanding how breast tumors arise and develop into different subtypes. Ultimately, this knowledge may help the development of novel therapies targeted to specific...

Stem Cells Of Infertile Men Used To Create Preliminary Sperm Cells
2014-05-02 08:25:30

April Flowers for redOrbit.com - Your Universe Online A new study, from the Stanford University School of Medicine and Montana State University, demonstrates that, when implanted into the reproductive system of a mouse model, stem cells created from adult, infertile men will yield primordial germ cells. Primordial germ cells normally become sperm cells. The findings, published in Cell Reports, help to further our understanding of a genetic cause of male infertility and basic sperm...

Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues of the body. Now, in a feat of reverse tissue engineering, Stanford University researchers have begun to unravel the complex genetic coding that allows embryonic cells to proliferate and transform into all of the specialized cells that perform myriad biological tasks. A team of...

Stem Cell Science Using Key Ingredient Found In Silly Putty
2014-04-14 04:22:24

redOrbit Staff & Wire Reports - Your Universe Online An ingredient found in Silly Putty could help scientists more efficiently turn human embryonic stem cells into fully functional specialized cells, according to research published online Sunday in the journal Nature Materials. In the study, researchers from the University of Michigan report how they were able to coax stem cells to turn into working spinal cord cells by growing them on a soft, extremely fine carpet in which the...

Rare, very small embryonic-like stem cells (VSELs) isolated from human adult tissues could provide a new source for developing regenerative therapies to repair complex tissues damaged by disease or trauma. The ability of these most-primitive, multipotent stem cells to differentiate into bone, neurons, connective tissue, and other cell types, and the proper criteria for identifying and isolating VSELs, are described in two articles in Stem Cells and Development, a peer-reviewed journal from...

Big Breakthrough In Stem Cell Manufacturing Technology
2014-04-01 13:07:09

University of Nottingham Scientists at The University of Nottingham have developed a new substance which could simplify the manufacture of cell therapy in the pioneering world of regenerative medicine. Cell therapy is an exciting and rapidly developing area of medicine in which stem cells have the potential to repair human tissue and maintain organ function in chronic disease and age-related illnesses. But a major problem with translating current successful research into actual products...

Simple Blood Test Could Predict Whether A Child Will Become Obese
2014-03-27 10:39:56

University of Southampton Scientists have found that a simple blood test, which can read DNA, could be used to predict obesity levels in children. Researchers at the Universities of Southampton, Exeter and Plymouth used the test to assess the levels of epigenetic switches in the PGC1a gene – a gene that regulates fat storage in the body. Epigenetic switches take place through a chemical change called DNA methylation which controls how genes work and is set during early life. The...
