From fetal tissue, it is possible to isolate fetal stem cells. These cells have special properties in regard to expansion capacity and neurological function. Our resource group have developed techniques for isolation and characterisation of fetal stem cells and we have also used these cells for intrauterine fetal stem cell transplantation. More recently, we are working on fetal stem cells in regards to tissue engineering with the aim to produce transplants for reconstructive surgery at severe congenital malformations.
