Stem cells from umbilical cord 'goo' delay type 1 diabetes progression

31 May 2023

Infusions of stem cells taken from umbilical cord jelly helped people with newly diagnosed type 1 diabetes reduce their need for insulin injections in a small study

Stem cells treat diabetes without triggering immune response in mice

8 May 2023

Genetically altered stem cells that are "invisible" to the immune system treated diabetes in mice without being wiped out by a destructive immune response

A girl with a rare disorder can now breathe more easily after receiving transfusions of a liquid that her sister's umbilical cord stem cells were grown in


Tiny human brain grown in lab has eye-like structures that 'see' light

17 August 2021

Small blobs of human brain grown in a dish have been coaxed into forming rudimentary eyes that respond to light. They could help understand eye disease or grow artificial retinas


Immune system T cells attacking growing cancer cells

The immune cells inside tumours hint at a new way to treat cancers

6 January 2020

A type of immune cell has been found inside tumours that helps our bodies mount attacks against cancer. Boosting these cells may lead to a new kind of treatment

2019 Preview: People will receive transfusions of artificial blood

18 December 2018

Volunteers will be injected with red blood cells grown from stem cells in the lab. If it works it could mean blood donors are no longer required

Stem cells implanted into the brain stop epilepsy seizures in rats

17 December 2018

A radical approach of implanting stem cells into the brain could stop epilepsy seizures at their source, but the treatment has only been tested in rats so far
