New stem-cell findings can help the body to cure itself

Researchers at Karolinska Institutet have identified an important mechanism that regulates how many new cells are produced by each intestinal stem cell. The study is published in the latest issue of the prestigious scientific journal, Cell. "This might eventually help us develop new drugs for things like neurological disorders and anaemia," says Professor Jonas Frisn.

In most organs of the body, old cells are continually being replaced by new. If too many new cells are produced, however, it can lead to overgrowth and tumour formation. Too few cells, on the other hand, can result in organ degeneration. It is therefore crucial that exactly the right number of cells are produced.

As many serious disorders cause a reduction in the production of new cells, scientists are keen to develop drugs that stimulate the process, which in turn could help the body to cure itself.

It has long been known that the new cells are often formed by immature cells known as stem cells, but the mechanism regulating the number of new cells produced has remained something of a mystery. However, in a new study to be published by Cell stem-cell researcher Jonas Frisn has succeeded in showing how the body's own stem cells do just this. Working alongside an American group of researchers, Professor Frisn and his team have identified a signal transduction process that regulates the degree of stem-cell division.

"Understanding how cell production is regulated increases our chances of producing drugs able to stimulate the endogenous production of new cells," says Professor Frisn.

He hopes that the new findings can be used to develop drugs that stimulate, for example, the formation of new nerve cells to treat conditions such as stroke and Parkinson's and skin cells to facilitate the healing of wounds. Professor Frisn is best known for his research on cerebral stem cells; the present study, however, has been carried out on stem cells in the intestine, one of the or
