Australian stem cell breakthrough

A University of New South Wales (UNSW) researcher based at the Diabetes Transplant Unit (DTU) at Sydney's Prince of Wales Hospital has produced a human embryonic stem cell (hESC) line without the use of any animal products. The breakthrough eliminates the risk of animal-to-human contamination in potential stem cell therapy treatments.

New public survey on stem cells

Stem cells are unique among human cells in that they possess the uncanny ability to develop into virtually any other cell of the body, offering a hypothetical tool kit for repairing diseased hearts, mending broken spinal cords, or correcting genetic diseases, among other hoped-for benefits.

New drugs help the immune system kill cancer cells

Researchers at the Lankenau Institute for Medical Research (LIMR) announced today that they have discovered an effective way to enlist the immune system to help chemotherapy destroy breast cancer cells. The work, led by LIMR researchers Alexander J. Muller and George C. Prendergast, is reported in the March 2005 edition of the leading international medical journal Nature Medicine.
