Researchers of the Berlin Institute for Medical Systems Biology (BIMSB) at the Max Delbrck Center for Molecular Medicine (MDC) Berlin-Buch have gained new insights into planarian flatworms, which are an attractive model for stem cell biology and regeneration. Close collaboration between four laboratories at the BIMSB led by Stefan Kempa, Christoph Dieterich, Nikolaus Rajewsky and Wei Chen has led to the identification of thousands of gene products, many of which are expressed and are...

New information has come to light explaining how injured skin cells and touch-sensing nerve fibers coordinate their regeneration during wound healing. UCLA researchers Sandra Rieger and Alvaro Sagasti found that a chemical signal released by wounded skin cells promotes the regeneration of sensory fibers, thus helping to ensure that touch sensation is restored to healing skin. They discovered that the reactive oxygen species hydrogen peroxide, which is found at high concentrations at wounds,...

(Ivanhoe Newswire) "“ A newly discovered group of stem cells from normal adult human lungs have the ability to regenerate virtually all parts of an injured mouse lung. The findings of Kajstura et al. also show organization of complete respiratory units in vivo within 14 days, including conducting airways and vessels. The authors used cell-surface c-kit receptors, known to mark hematopoietic and cardiac stem cells, to isolate and analyze these cells from adult lungs. They believe that...

A team led by developmental biologist Professor Christophe Marcelle has nailed the mechanism that causes stem cells in the embryo to differentiate into specialised cells that form the skeletal muscles of animals' bodies. The scientists published their results in the British journal Nature on Monday (May 16). Scientists world wide are racing to pin down the complex molecular processes that cause stem cells in the early embryo to differentiate into specialist cells such as muscle or nerve...

Worm with abundant ability to regenerate relies on ancient gene to make decisions Most people don't think worms are cool. But the tiny flatworm that Northwestern University scientist Christian Petersen studies can do something very cool indeed: it can regenerate itself from nearly every imaginable injury, including decapitation. When cut in half, it becomes two worms. This amazing ability of the planarian flatworm to regenerate its entire body from a small wedge of tissue has fascinated...

What does it take to regenerate a limb? Biologists have long thought that organ regeneration in animals like zebrafish and salamanders involved stem cells that can generate any tissue in the body. But new research suggests that multiple cell types are needed to regrow the complete organ, at least in zebrafish. Researchers at Washington University School of Medicine in St. Louis have shown that cells capable of regenerating a zebrafish fin do not revert to stem cells that can form any tissue....

New research in the FASEB Journal provides scientific basis for the first clinical trial of engineered vascular grafts in children If pending clinical trials prove successful, a new discovery published in The FASEB Journal (http://www.fasebj.org) could represent a major scientific leap toward human tissue regeneration and engineering. In a research report appearing online, Yale scientists provide evidence to support a major paradigm shift in this specialty area from the idea that cells added...

Ever since animals, such as lizards and starfish, were observed regenerating missing body parts, people have wondered where the new tissues come from. In the case of the planarian flatworm, Whitehead Institute researchers have determined that the source of this animal's extraordinary regenerative powers is a single, pluripotent cell type. Most advanced animals, including mammals, have a system of specialized stem cells. In humans, we have blood stem cells in our bone marrow that make blood...

A seldom-studied gene known as notum plays a key role in the planarian's regeneration decision-making process, according to Whitehead Institute scientists. Protein from this gene determines whether a head or tail will regrow at appropriate amputation sites. Since the late 1800s, scientists have been fascinated by the planarian's amazing ability to regenerate its entire body from a small wedge of tissue. Whitehead Member Peter Reddien and former postdoctoral fellow Christian Petersen recently...
