Single stem cells from bone heal a broken heart

Myocardial infarction results in irreversible damage to the heart that can cause congestive heart failure. The lasting damage results from the limited ability of the myocardium to regenerate and self-repair. Douglas Losordo and colleagues from Tufts University now document the existence of a previously unrecognized subset of human bone marrow–derived stem cells with therapeutic potency for myocar...

Nanotubes inspire new technique for healing broken bones

Scientists have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue. The new technique could change the way doctors treat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing. The report appears in the June 14 issue of the American Chemical Society's journal Chemistry of Materials. ACS is the...

UCLA imaging study of children with autism finds broken mirror neuron system

New imaging research at UCLA detailed Dec. 4 as an advance online publication of the journal Nature Neuroscience shows children with autism have virtually no activity in a key part of the brain's mirror neuron system while imitating and observing emotions. Mirror neurons fire when a person performs a goal-directed action and while he or she observes the same action performed by others. Neu...

UT Southwestern researchers find gene mutation that leads to 'broken hearts'

Researchers at UT Southwestern Medical Center have identified a group of fruit fly gene mutations responsible for "broken hearts" in the embryonic stages of development, a discovery that could help identify genes that cause human heart defects. "We engineered a fruit fly so that the heart would glow in the dark and found a new type of malformation, completely unexpectedly," said Dr. Eric...

How fish mend a broken heart

New evidence to explain how a common tropical fish mends a broken heart may suggest methods for coaxing the damaged hearts of mammals to better heal, researchers report in the November 3, 2006 issue of Cell, published by Cell Press. The researchers found that the hearts of zebrafish harbor progenitor cells that spring into action to restore wounded heart muscle. Cells from a membrane layer...
