In "before" and "after" photos from advertisements for wound-healing ointments, bandages and antibiotic creams, we see an injury transformed from an inflamed red gash to smooth and flawless skin. What we don't appreciate is the vital role that our own natural biomolecules play in the healing process, including their contribution to the growth of new cells and the development of new blood vessels that provide nutrients to those cells. Now, UCLA researchers led by Heather Maynard, a...

Insight Into Tissue Regeneration Offered From Newt Transcriptome
2013-02-20 13:06:23

BioMed Central Scientists have identified protein families expressed during tissue regeneration in newts, providing the groundwork for research into whether particular sets of genes are used for the purpose. The transcriptome — the map of all RNA molecules — of the newt is published this week in BioMed Central's open access journal Genome Biology. Notophthalmus viridescens is a useful model in regenerative medicine, thanks to its ability to regenerate tissue, and this data...

Epidermal growth factor has been found to speed the recovery of blood-making stem cells after exposure to radiation, according to Duke Medicine researchers. The finding could open new options for treating cancer patients and victims of dirty bombs or nuclear disasters. Reported in the Feb. 3, 2013, issue of the journal Nature Medicine, the researchers explored what had first appeared to be an anomaly among certain genetically modified mice with an abundance of epidermal growth factor in...

Tadpole And The Tail: Studying The Secrets Of Human Healing
2013-01-14 10:08:34

Brett Smith for redOrbit.com - Your Universe Online Humans have the capacity to regenerate tissue after suffering an injury, but many animals have the ability to regenerate whole limbs after an amputation. A group of UK researchers decided to look into this ability in tadpoles, which can regrow a tail that has been severed. Their results proved to be somewhat counter intuitive–showing that a molecule previously thought to be harmful to cells is involved in the process....

Understanding Organ Regeneration Using Planarian Flatworms
2012-10-25 12:26:38

In a new study published in the October 16 issue of Developmental Cell, corresponding author Professor of Cell and Developmental Biology and Howard Hughes Medical Institute Investigator Phillip Newmark and colleagues report the identification of genes that control growth and regeneration of the intestine in the freshwater planarian Schmidtea mediterranea. How animals repair their internal organs after injury is not well understood. Planarian flatworms are useful models for studying this...

While it is well known that starfish, zebrafish and salamanders can re-grow damaged limbs, scientists understand very little about the regenerative capabilities of mammals. Now, researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine report on the regenerative process that enables rats to re-grow their bladders within eight weeks. In PLOS ONE, a peer-reviewed, online publication, the scientists characterize this unique model of bladder regeneration with the...

Regenerated Lizard Tails Not A Perfect Match To Original Tail
2012-10-10 08:47:00

Lawrence LeBlond for redOrbit.com - Your Universe Online Some lizards have the innate ability to re-grow their tails when their original one gets severed. However, this natural regenerative ability does not occur in a perfect way. In other words, the new tail, based on studies by a team of scientists from two Arizona schools, is quite different from the original appendage it replaces. Scientists from Arizona State University and University of Arizona examined the anatomical and...
