Pan-Pancreas PANDA
Multi-dataset corpus for pancreas cell identity + zero-shot transfer + mechanistic discovery.

Held-out labeled validation
Baron 2016 mouse subset — has full canonical islet labels (alpha/beta/delta/gamma/epsilon/ ductal/acinar/endothelial/immune) but is a completely independent scRNA-seq study from a different lab. Zero-shot transfer of PANDA-pancreas predictions to Baron gives an apples-to-apples accuracy measurement across labs.
Held-out unlabeled discovery target
Veres 2019 hPSC-directed differentiation (GSE114412) — human pluripotent stem cell differentiation to SC-beta cells with an off-target enterochromaffin population. Weakly labeled by day-of-differentiation only; PANDA's cell-type predictions become hypothesis- generating annotations.
