A team of scientist from the RIKEN Center for Developmental Biology in Japan, in collaboration with the University of Sciences of Tokyo and other Japanese institutions has been successfully grown skin and hair in the laboratory. This breakthrough could be very useful for transplants.
These researchers have been able to cultivate a complex tissue complex that includes skin, hair follicles and sebaceous glands. Furthermore, not only have been able to obtain the fabric, but have implanted in live mice and found that establish the right connections other elements of the body, such as nerve and muscle fibers run correctly.

So far, they had been properly cultivated implantable sheets of epithelial cells in the laboratory , but lacked the sweat glands and sebaceous that make operation possible as a normal tissue.
To carry out their tests, the scientists used mouse cells and treated with chemicals to transform them into induced pluripotent stem cells, which is the type that has the ability to generate most tissues.
In the culture, the cells properly developed a embryoid body (EB), which is the name given to a three - dimensional group of cells that is partially similar to developing embryo in a real body.Subsequently, the EB were implanted in immunodeficient mice and differentiated tissue were changing gradually, mimicking the pattern of an actual embryo.
