Rosa26 CreER-mediated clonal analysis reveals heterogeneous contribution of E9.5 progenitors to pancreas organogenesis. a Schematic overview of lineage relationships based on previous global lineage tracing. b Schematic overview of strategy applied to identify fates of clonal progeny from E9.5 pancreatic progenitors. c 3D maximum intensity projection (MIP) of a large, multipotent clone containing acinar (CPA1), progenitors lining the ducts (SOX9) and endocrine progeny (PAX6, from other multipotent clone) d. Scale bars, 100 µm c and 15 µm d. e 3D MIP of a bipotent clone containing endocrine (insets 1 and 2) and ductal (inset 3) clonal progeny f. Scale bars, 100 µm e and 10 µm f. g 3D MIP and optical section (inset) showing a single-labelled endocrine cell after clonal analysis from E9.5 to E14.5. Note the localisation of the GFP+ cell in an E-CADLow endocrine cluster. Scale bars, 80 µm and 15 µm (inset). h Quantification of clone sizes and compositions following clonal analysis from E9.5 to E14.5 (n = 170 embryos, 20 with clones, 1 excluded due to poor immunocytochemistry-the images displayed show representative data from those)
