Is nutrition the future of brain health?

We take it for granted that our body can regenerate cells that become injured or simply wear out and die. For most of the 20th century, however, scientists were convinced that one organ—the brain—lacked that ability. ...

Engineered hot fat implants reduce weight gain in mice

Scientists at the University of California, Berkeley, have developed a novel way to engineer the growth and expansion of energy-burning "good" fat, and then found that this fat helped reduce weight gain and lower blood glucose ...

Neurons reprogrammed in animals

Building on earlier work in which they disproved neurobiology dogma by "reprogramming" neurons—turning one form of neuron into another—in the brains of living animals, Harvard Stem Cell Institute researchers have now ...

Source of liver stem cells identified

Howard Hughes Medical Institute (HHMI) scientists have identified stem cells in the liver that give rise to functional liver cells. The work solves a long-standing mystery about the origin of new cells in the liver, which ...

Stem cell

Stem cells are cells found in most, if not all, multi-cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and differentiating into a diverse range of specialized cell types. Research in the stem cell field grew out of findings by Canadian scientists Ernest A. McCulloch and James E. Till in the 1960s. The two broad types of mammalian stem cells are: embryonic stem cells that are isolated from the inner cell mass of blastocysts, and adult stem cells that are found in adult tissues. In a developing embryo, stem cells can differentiate into all of the specialized embryonic tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing specialized cells, but also maintain the normal turnover of regenerative organs, such as blood, skin or intestinal tissues.

Stem cells can now be grown and transformed into specialized cells with characteristics consistent with cells of various tissues such as muscles or nerves through cell culture. Highly plastic adult stem cells from a variety of sources, including umbilical cord blood and bone marrow, are routinely used in medical therapies. Embryonic cell lines and autologous embryonic stem cells generated through therapeutic cloning have also been proposed as promising candidates for future therapies.
