Growing tissues

...embryonic stem cells could do this. Work is in the embryo stage but efforts are now being made to turn the adult cells into tissues such as muscle, cartilage and brain cells, which can be transplanted back into the patient.// Ihor Lemischka of the US's Princeton University said: "The work is very exciting...

Stem cells form blood vessels

... ailing hearts have coaxed stem cells from a human embryo into forming tiny blood vessels. According to Robert Langer, leader of a laboratory team at the Massachusetts Institute of Technology, this is the first time human embryonic stem cells have been nurtured to the point where they will organize into blo...

Womb may have impact upon Blood Pressure

Stem Cells, Tumor Cells Share Similar Properties: Scope For Treatment and Prevention?

... result in deadly tumors. Cells in the very early embryo have no specific function assigned to them and can perform any type of work. Soon, however, they begin differentiating into more specific types, finally becoming specialized cells like neurons, blood, or muscle. As this continues, the cells should ...
