Stem Cells News and Research

RSS

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Mature muscle fibers can revert to become cancerous

Mature muscle fibers, rather than their less-developed neighbors, are the tissues that turn malignant in a soft-tissue cancer that strikes children and teens, researchers at UT Southwestern Medical Center and Children's Medical Center Dallas have found.

Nature to change study reporting method of creating stem cells without destroying embryos

Officials from the journal Nature have said they plan to change a paper published in the journal's Aug. 24 edition describing a technique that could derive human embryonic stem cells without destroying the embryo to further clarify that none of the embryos used in this particular study survived the experiment, the Chicago Tribune reports.

Appointee to head National Cancer Institute discusses research funding cuts

John Niederhuber, a surgeon whom President Bush on Tuesday appointed as National Cancer Institute director, on Wednesday said that he hopes to find new nontoxic cancer medications but added that the agency likely will have to eliminate some programs because of budgetary issues, the New York Times reports.
