Recent studies, using genetic labeling and tracing of progenitors, direct single cell analyses, colony assays, and enrichment of the minor population of progenitor cells through the use of cell surface markers, have strongly suggested that pancreatic progenitor cells with various frequency and lineage potentials, including the multipotent progenitors that give rise to endocrine, exocrine, and duct cells, exist in the developing and adult pancreas.

This model may explain why only drastic injuries lead to effective activation of the progenitor cell compartment of the higher hierarchy, whereas under steady state, pregnancy, and milder injuries, recruitment of preexisting mature cells or their immediate monopotent progenitors could be sufficient to restore metabolic homeostasis.
