Scientists at the Medical Research Council (MRC) have developed a new method to investigate how human testes develop in baby boys before they are born. MRC researchers obtained ethical approval to take testicular tissue from fetuses donated after termination. This tissue was then grafted into mice and cells developed normally, as if inside a womb, over a six week period. This landmark advancement will allow scientists to study what factors could lead to testicular germ cell cancer (TGCC)...
