WebMorover, after destruction of β-cells by streptozotocin, β-cells regenerated from cells that had previously expressed glucagon. Thorel et al. (2010) produced near total ablation of β-cells in the mouse pancreas by conditional expression of diphtheria toxin. While the mice were kept alive by insulin injections, β-cells regenerated (Fig. 5.16). 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.
