According to a UK/German research, the cells found in a man’s testicles can do a lot aside from just producing sperm, as they may provide any type of cell in his body.

The researchers say that sperm cells can be altered into stem cells with the same sort of characteristics to those that are found in the embryo.

The Study, which has been published in the journal Nature, shows some ray of hope for a supply of “repair tissue” to the other parts of the body.

However, a UK expert says that it’s too early to reach at a firm conclusion.

There are chances of personalised treatment for patients with the ability to transform cells taken from an adult back into stem cells and afterward into a wide range of tissue types.

The procedure would also help to avoid the ethical controversies regarding use of cells that are taken from embryos.

In their study the researchers from King’s College London used 22 different samples that were taken from biopsies or from medical castrations.

The researchers extracted a kind of cell (named the ‘sperm precursor cell’) from these procedures. These adult stem cells have a fixed role as to become a sperm cell.

Then they manipulated them chemically in the laboratory in a very similar state to cells found in the embryo that can make almost all the cell types in the body.

It is still unclear whether these cells would be safely used in humans in the coming days or not.
