How are body parts grown?

Daily Trust - - DIGEST -

The new body part be­gins as a glass mould, based on the orig­i­nal, which is sprayed with a syn­thetic honeycomb-like ma­te­rial to cre­ate a frame­work for stem cells to cling to.

The mould is then re­moved and the honeycomb cov­ered with mil­lions of ‘blank cells’ which, with the right nu­tri­ents, can turn into the car­ti­lage of the or­gan.

Mean­while, the skin on an­other area of the body is grad­u­ally stretched by a small bal­loon placed un­der the sur­face and in­flated un­til it is loose enough to ac­com­mo­date the or­gan.

Af­ter sev­eral months, the body part is taken out from un­der the skin and sewn into the right place.
