Summary:
Scientists from The Danish Stem Cell Center (DanStem) at the University of Copenhagen and Hagedorn Research Institute have gained new insight into the signaling paths that control the body's insulin production. This is important knowledge with respect to their final goal: the conversion of stem cells into insulin-producing beta cells that can be implanted into patients who need them. The research results have just been published in the well-respected journal PNAS.
Insulin is a hormone produced by beta cells in the pancreas. If these beta cells are defective, the body develops diabetes. Insulin is vital to life and therefore today the people who cannot produce their own in sufficient quantities, or at all, receive carefully measured doses – often via several daily injections. Scientists hope that in the not-so-distant future it will be possible to treat diabetes more effectively and prevent secondary diseases such as cardiac disease, blindness and nerve and kidney complications by offering diabetes patients implants of new, well-functioning, stem-cell-based beta cells.
This new knowledge about the characteristics of the Notch signaling mechanism will enable scientists to design new experimental ways to cultivate stem cells so that they can be more effectively converted into insulin-producing beta cells.
