A third team of researchers has found a way to convert an ordinary skin cell into valued embryonic-like stem cells, with the potential to grow batches of cells that can be directed to form any kind of tissue.

CAMBRIDGE Dec 14, 2004 - Researchers at the Massachusetts Institute of Technology have used rat cells to grow dime-sized swatches of heart tissue that twitch like a beating heart when an electrical current passes through.

Pulsing transplanted heart cells with electrical current helps them grow into mature cardiac cells, bringing doctors closer to a grow-your-own heart patch, US researchers said on Tuesday.

Scientists studying mice said they have found what may be a master cardiac stem cell -- able to change into the three major cell types in a mammal's heart -- in a finding that could help guide heart repair in people.

RIO DE JANEIRO, Brazil  - Infusing patients with  bone marrow cells can reinvigorate their dying hearts and grow  tiny new arteries and heart muscle tissue, a treatment that may  one day make many heart transplants unnecessary, Brazilian  researchers said on Friday.

Researchers at the University of Pennsylvania School of Veterinary Medicine have identified the growth factors essential to allow spermatogonial stem cells -- the continually self-renewing cells that produce sperm -- to exist in culture indefinitely.

Cells critical to sperm development have been grown in the lab and used to father baby mice, US researchers say. They said the development could lead to easier ways to genetically manipulate animals, and said

Researchers at MIT are one step closer to creating patches for damaged hearts: They've used rat cells to construct a beating slice of cardiac tissue about the size of a dime. By Kristen Philipkoski.

Scientists in the United States said on Wednesday they had identified a protein produced by the heart during development which they believe could help the organ repair itself after a heart attack.

Peter Cummins lay still as doctors administered 20 injections into the 81-year-old's calves and thighs, hoping the genetic experiment will spur new blood vessels to grow around his clogged leg arteries.    The experiment at the National Institutes of Health marks a resurgence in attempts to get the body to grow its own bypasses, at first in the legs and, if that works, perhaps later in the heart...

An American scientific study shows that artificial hearts can keep heart-transplant candidates alive before the donor organ is available and it also helps prolong their life after transplant.
