WebThey’ll do this by taking beta cells from humans and mice with high blood sugar. They’ll use genetic scissors, known as CRISPR technology, to chop out the Mtfp1 gene from the cells’ DNA. Then they’ll check the shape of the beta cells’ mitochondria with a powerful microscope and see how much insulin is released. Web27 okt. 2009 · When released from the pancreas, insulin helps other cells in the body take up sugar from the bloodstream, feeding the cells and bringing blood sugar levels down again. Diabetes, in its several forms, arises when the system goes awry. Before its release, insulin is stored in beta cells in secretory granules.
