Human hearts scar following injury from heart attack, and the scarring response contributes to chronic heart disease and death.

The healing response in the MRL mouse, however, differed greatly from that of the typical mouse.

The MRL mouse displayed early movement of cardiomyocytes into the wound site, and DNA synthesis and proliferation of these cells.

The MRL mouse heart also demonstrated better revascularization (restoration of blood supply) at the site of injury, which is necessary to help cells thrive and avoid death.

According to the scientists, the MRL mouse studies demonstrate that "mammalian hearts have significant capacity to regenerate." ...

Millions of dollars are spent each year to develop tissue engineering products and procedures.

In fact, some engineered tissues have already been approved by the FDA.

One of the first tissues to be engineered and used clinically is bone.

Engineered bones, cartilage, tendons, and ligaments may benefit people who suffer from bones that will not fuse, defective tendons, or arthritic joints, as well as those who need dental implants (which require strong bone tissue).

These regenerated tissues will one day eliminate the need for standard therapy, which includes stai...

There were no prizes awarded.

"We specifically removed that aspect," Stroud said, "which allowed students to focus on their own interest in science." Students from Hancock Elementary School, Clarksburg Elementary School, Silvio O.

Conte Middle School, Fayerweather School in Cambridge and Hiland Hall School in Bennington, Vt., also participated in the event.

There was a keynote speaker, Dr.

Gwendolyn F.

Elphick, a neurologist and a postdoctoral fellow at Rhode Island Hospital.

Stroud said the conference journal, which was printed by Williams College, is an important academic resource.

"It's going to be a teaching tool and something for students to use," he said.

"Others could look through the journal and repeat the experiments to test for their own results." The event, known as a "Kids Inquiry Conference," received support from the New York City Foundation's Math and Science Improvement Grant.
