 and male infertility. His team was the first in the world to isolate a new type of stem cell from adult mouse testes

s. It was able to show that some of these stem cells, called multipotent adult germline stem cells (maGSCs), turned into heart, muscle, brain and other cells. Prof Nayernia and his team proposed that similar cells could be extracted from men using a simple testicular biopsy. On the basis of these cells, new stem cell techniques could be developed in order to treat a variety of illnesses.

In 2006, he was appointed as Professor of Stem Cell Biology at the Newcastle University Institute of Human Genetics.
In 2009, he created human sperm-like cells from male stem cells in the laboratory for the first time. Previously, in 2006, he used sperm created from embryonic stem cells to impregnate mice. The mice produced 7 pups, although one died and the other six had health problems.
In 2010, he discovered a new marker for detection of breast cancer stem cells. This findings define this novel marker and its effector signaling pathways as key factors in the proliferation and survival of breast cancer stem cells.
