Lineage tracing of pancreatitis tuft cells in wild type mice reveals acinar cell origin. (A) Schematic of tamoxifen and caerulein treatment for lineage tracing in Ptf1aCreERTM/+; RosaYFP mice. (B) Co-immunofluorescence for tuft cell marker phalloidin (red, labels the microvilli and actin rootlets of tuft cells) and YFP, green, in caerulein-treated pancreata. Scale bar, 5 μm.
