Key factor in brain development revealed, offers insight into lissencephaly

In the earliest days of brain development, the brain's first cells - neuroepithelial stem cells - divide continuously, producing a population of cells that eventually evolves into the various cells of the fully formed brain.

REST protein protects embryonic stem cells' versatility and self-renewal

A protein known as REST blocks the expression of a microRNA that prevents embryonic stem cells from reproducing themselves and causes them to differentiate into specific cell types, scientists at The University of Texas M. D. Anderson Cancer Center report in the journal Nature.

New hope for victims of macular degeneration and retinitis pigmentosa

Scientists at Schepens Eye Research Institute have discovered what chemical in the eye triggers the dormant capacity of certain non-neuronal cells to transform into progenitor cells, a stem-like cell that can generate new retinal cells.

Toddlers affected most by secondhand smoke exposure at home

Secondhand smoke in the home appears to induce markers for heart disease as early as the toddler years, researchers reported at the American Heart Association's 48th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.

Study shows Parkinson's disease drug dopamine might work in cancer patients

A study published in the March 13 online issue of The Journal of Clinical Investigation shows that dopamine, a drug currently used to treat Parkinson's disease and other illnesses, also might work in cancer patients.

Nuclear protein SATB1 triggers aggressive breast cancer

SATB1 is a nuclear protein well known for its crucial role in regulating gene expression during the differentiation and activation of T cells, making it a key player in the immune system.

Cell therapy for rejuvenating aged brain by injection of human umbilical cord blood

When human umbilical cord blood cells (UCBC) were injected into aged laboratory animals, researchers at the University of South Florida (USF) found improvements in the microenvironment of the hippocampus region of the animals' brains and a subsequent rejuvenation of neural stem/progenitor cells.

High zinc status in lung cells slows growth and induces DNA

Researchers at the University of Maryland at College Park have discovered that Normal Human Bronchial Epithelial (NHBE) cells cultured in medium with elevated zinc level, at the high end of plasma zinc attainable by oral supplementation, demonstrated inhibition of cell growth, up-regulation of growth arrest and DNA damage-induced gene (Gadd45) mRNA and protein expression, and blockage of G2/M cell cycle progression.

Elusive pancreatic stem cells found in adult mice

Just as many scientists had given up the search, researchers have discovered that the pancreas does indeed harbor stem cells with the capacity to generate new insulin-producing beta cells.

Adult stem cell application effective in treatment of peripheric vascular disease

Multipotent adult progenitor stem cells extracted from bone marrow, and known as MAPCs, have proved to be effective in the regeneration of blood vessel tissue and also in muscle tissue when treating peripheric vascular disease.

University of Minnesota researchers have created a beating heart in the laboratory

By using a process called whole organ decellularization, scientists from the University of Minnesota Center for Cardiovascular Repair grew functioning heart tissue by taking dead rat and pig hearts and reseeding them with a mixture of live cells. The research will be published online in the January 13 issue of Nature Medicine.

Scientists identify cells that promote formation of lethal lung metastases

Cancer patients usually ask what can be done after a primary tumor has already spread, or metastasized, to other organs.

Cardiac stem cell therapy research

Since the year 2000, much has been learned about the potential for using transplanted cells in therapeutic efforts to treat varieties of cardiac disorders.

Scientists identify and repress breast cancer stem cells in mouse tissue

By manipulating highly specific gene-regulating molecules called microRNAs, scientists at Cold Spring Harbor Laboratory (CSHL) report that they have succeeded in singling out and repressing stem-like cells in mouse breast tissue - cells that are widely thought to give rise to cancer.
