The results of this study that found Carvedilol benefited both blacks and whites equally. Blacks suffer from heart failure twice as often as whites and their heart failure seems to strike earlier and progress faster. For these reasons, it has become important to differentiate the most effective drug treatment between blacks and whites. Stem Cells Cultivated From Cadavers Scientists from the Salk Institute in California have taken tissue samples from cadavers shortly after death and developed them into cells that can grow, divide and form specialized brain cells. This may be a breakthrough in using adult cells capable of becoming stem cells.
Stem cells are master cells that can grow into virtually any type of cell in the body.
Embryos are the richest source of human stem cells but religious groups oppose their use because they may be gathered from aborted tissue. The scientists used biopsy tissue from 23 people ranging from 11 weeks to 72 years old. All of the people had suffered from brain disorders. The researchers were using them to study the cell biology of the various brain diseases. The scientists used special growth factors to obtain cells from the tissue.
