Test tube kidneys grown to combat deadly organ disease 'go rogue' and sprout BRAIN and muscle cells, scientists reveal

Miniature kidney's which were being grown in a laboratory have suddenly started forming brain and muscle cells.

The lab-grown organs which were created in test tubes started to 'go rogue' and began behaving in a completely unexpected way.

The kidneys, also known as kidney organoids, were expected to form different kinds of kidney cells by scientists conducting the research, reports the Daily Star.

Organoids are developed from human stem cells and could one day be used to treat people who suffer from kidney diseases.

Benjamin D. Humphreys, the director of the Division of Nephrology at the Washington University School of Medicine in St Louis, said that there is a lot of excitement surrounding the idea of organoids being grown as potential treatments.
​
However he added that scientists haven't quite learnt that the organoid cells may not mirror the behaviour of human cells and therefore produce different results.
