Scientists grow artificial liver |
| Telegraph.co.uk |
| 1st November, 2006- British scientists have grown a miniature liver from stem cells in a world breakthrough. The tiny organ, about the size of a 1p coin, will be used for drug testing and reduce the need for animal experiments. |
| Scientists said it was the first stage to creating sections which can be used to repair damaged livers and even a full-size functioning version. The creation of the mini-liver by scientists at Newcastle University involved taking stem cells - blank cells capable of developing into different types of tissue - from the umbilical cords of newborn babies. |
| The cells were then placed in a “bioreactor” developed by NASA that mimics the effects of weightlessness and allows them to multiply rapidly. Using hormones and chemicals, the stem cells are then coaxed into turning into liver tissue. |
| The Newcastle University team is the first to have done it using cord blood stem cells. |
| In its current form, use of the mini organ for trialing new medicines could avert disasters such as the recent Elephant Man case where human volunteers suffered horrendous physical damage testing new drugs. |
| Within a few years it is hoped that liver damage caused by injury, disease and alcohol and drug abuse will be rectified using sections of an artificially grown organ. |
| There could come a time when umbilical cord blood from millions of newborns every year is banked creating a worldwide donor register for liver dialysis and transplant. |
| Alison Rogers of the British Liver Trust said: “Stem cell technology represents a huge leap forward in treating many diseases. With liver disease in particular it has the potential for tremendous advances.” |
