PLoS Genet. 2020; 16(10): e1009069. doi: https://doi.org/10.1371/journal.pgen.1009069The authors used mouse conditional gene knock-out models to investigate the role of Insulin-like growth factor-2 (Igf2) in pancreatic growth and function. When Igf2 was deleted specifically in mesenchyme-derived cells (but not when deleted in exocrine and endocrine cells), the entire pancreas was smal...
