Discovery of a key cell-signaling pathway

University of Alabama at Birmingham (UAB) researchers have discovered a key cell-signaling pathway that regulates cell progression and switches on front-to-back body patterning in tadpoles.

A new source of islet cells

The shortage of islet cells limits the development of islet transplantation. One new approach was reported in the October 21 issue of the World Journal of Gastroenterology because of its great significance in enhancing the output of islet cells.

Stem cells from a person's own umbilical cord effectively treat blood and immune disorders, juvenile diabetes

Two separate data abstracts displayed at the annual scientific meeting of the AABB - an international association of medical professionals and institutions focused on transfusion, transplantation and cellular therapy - highlight the increasing therapeutic use of autologous (one's own) cord blood stem cells for transplant and regenerative medicine, including treatments for blood and immune disorders, juvenile diabetes and neurological repair.

Dietary fatty acids may help prevent diabetes

Omega-3 fatty acids have long been touted for their heart-healthy and brain-boosting benefits. Consider cod liver oil, fortified infant formula and enriched eggs.

Unique role for blood formation gene MLL identified

All blood cell production in adults depends on the steady work of a vital gene that if lost results in early bone marrow failure, Dartmouth Medical School cancer geneticists have found.

Embryonic stem cell strategy advanced with UCSF finding

UCSF scientists are reporting what they say is a significant improvement in the technique for genetically reprogramming mouse cells to their embryonic state, a process that transforms the cells, in essence, into embryonic stem cells.

Tendons found to contain a small subset of previously unknown adult stem cells

Tendon, the cord-like tissue that connects muscle to bone, contains a small subset of previously unknown adult stem cells, scientists at the National Institute of Dental and Craniofacial Research (NIDCR) part of the National Institutes of Health, and their colleagues have discovered.

Mutations in the insulin gene can cause permanent neonatal diabetes

Mutations in the insulin gene can cause permanent neonatal diabetes, an unusual form of diabetes that affects very young children and results in lifelong dependence on insulin injections, report researchers from the University of Chicago and Peninsula University (Exeter, UK) in Sept. 18, 2007, issue of the Proceedings of the National Academy of Sciences, published early online.

Clearer picture of how a dividing cell rebuilds the nuclear envelope

Just how a dividing cell rebuilds the nuclear envelope, the protective, functional wrapping that encases both the original and newly copied genetic material, has been a source of controversy for the last 20 years.

First common height gene identified by researchers behind 'obesity gene' finding

Whilst we all know that tall parents are more likely to have tall children, scientists have been unable to identify any common genes that make people taller than others. Now, however, scientists have identified the first gene, known as HMGA2, a common variant of which directly influences height.

New options in treating pigmentation disorders

Melanocytes are not the only cells responsible for differences in skin coloration. New research from the University of Cincinnati (UC) has shown that some of the most basic cells on the skin's surface influence pigment production and help regulate skin coloration.

New findings on cholesterol metabolism

A team of researchers investigating cholesterol and lipid transport has performed experiments that cast serious doubt on the dominant hypothesis of how the body rids its cells of "bad" cholesterol (LDL) and increases "good" cholesterol (HDL).

The skeleton is an endocrine organ

Bones are typically thought of as calcified, inert structures, but researchers at Columbia University Medical Center have now identified a surprising and critically important novel function of the skeleton.

Scientists tackle gene doping in athletes

Gene doping has the potential to spawn athletes capable of out-running, out-jumping and out-cycling the strongest of champions.

Reducing inflammation plays key role in type 1 diabetes therapy

Researchers at Beth Israel Deaconess Medical Center (BIDMC) have found that a triple combination therapy consisting of both tolerance-inducing and anti-inflammatory properties is successful in abolishing adverse autoimmunity against insulin-producing cells in a mouse model of Type 1 diabetes.
