This story about growing a liver in a lab highlights the fact that although stem cell research is incredibly useful, embryonic stem cell research specifically has never led to any significant results.
British scientists have grown the world's first artificial liver from stem cells in a breakthrough that will one day provide entire organs for transplant.
The technique that created the 'mini-liver', currently the size of a one pence piece, will be developed to create a full-size functioning liver.
Described as a 'Eureka moment' by the Newcastle University researchers, the tissue was created from blood taken from babies' umbilical cords just a few minutes after birth.
Umbilical cord stem cells and adult stem cells are leading to all sorts of fruitful treatments that do not require the creation and destruction of human beings as does embryonic stem cell research.
