Researchers clone human embryonic stem cells

Creating stem cells from skin.

Researchers have converted human skin cells into embryonic stem cells using the same process involved in cloning, which have the capability to turn into any type of cell in the body. Stem cell researchers have reached a long-sought milestone in “regenerative” medicine that seeks to provide rejection-free replacement transplant tissues to patients.

Study Shows The Human Heart Can Grow New Cells

Study Shows The Human Heart Can Grow New Cells

Heart muscle cells can be grown from human embryonic stem cells, but new research suggests the adult heart can grow new cells, too. 
 

The human heart has a notorious reputation for being unable to heal itself, but new research suggests it is capable of at least some self-repair. Using carbon dating to gauge the age of heart cells, scientists have found that low numbers of new heart cells are continuously being created throughout a person’s life. This raises the possibility that we may one day be able to use drugs to directly stimulate this regenerative capacity to patch up damaged hearts, rather than relying on cell-transplantation therapies.

British Scientists Could Become First To Create Synthetic Human Blood

British Scientists Could Become First To Create Synthetic Human Blood

Scientists want to create blood from embryonic stem cells 

British scientists are on course to become the first to create synthetic human blood from embryonic stem cells, it emerged today.

The ground-breaking project could provide an unlimited supply of blood for emergency transfusions free of the risk of infection.

Because stem cells multiply indefinitely, it would be possible to enormous quantities, researchers said..

Transplanted Stem Cells Undo Birth Defects

Transplanted Stem Cells Undo Birth Defects 

 Neural stem cells, tagged green with a fluorescent dye, have been transplanted among the brain cells (red) of a mouse born with brain damage after its mother was given heroin during pregnancy.

By injecting stem cells directly into the brain, scientists have successfully reversed neural birth defects in mice whose mothers were given heroin during pregnancy. Even though most of the transplanted cells did not survive, they induced the brain’s own cells to carry out extensive repairs.

A Source Of Stem Cells From Men

A Source Of Stem Cells From Men 

 Stem cells from adult human testes normally produce only sperm, but when cultured in the lab with special growth factors, they begin to resemble embryonic stem cells and can differentiate into many adult cell types.

Stem cells from human testes could be used for personalized medicine.  Adult stem cells that behave much like embryonic ones have been isolated from human testes, raising hopes for a new source of versatile stem cells without genetic manipulation or the destruction of embryos. If the new stem cells can be used therapeutically, a simple testicular biopsy could provide the starting material for personalized regenerative medicine.
