The protein known as "Pancreatic Progenitor Cell Differentiation and Proliferation Factor-Like" (PPCDPFL) is presumed to be involved in the intricate process of pancreatic development and cellular turnover. This factor-like protein is suggested to play a role in guiding progenitor cells in the pancreas through the stages of differentiation into fully functional pancreatic cells, including both endocrine and exocrine components.

Pancreatic development is a highly regulated process involving the proliferation of pancreatic progenitor cells and their subsequent differentiation into specialized cell types, such as insulin-producing beta cells, glucagon-secreting alpha cells, somatostatin-producing delta cells within the islets of Langerhans, and acinar cells responsible for digestive enzyme production. PPCDPFL likely influences these pathways by interacting with key regulatory molecules and signaling cascades.The "factor-like" designation in PPCDPFL's name implies that it has a functional resemblance to growth factors or differentiation factors, which are known to bind receptors and initiate signal transduction pathways leading to cellular growth, differentiation, or proliferation. The precise mechanisms by which PPCDPFL influences pancreatic progenitor cells may involve modulation of transcription factors specific to pancreatic development, such as PDX1, or signaling pathways like Notch, Wnt, and FGF, which are critical for the maintenance and maturation of these progenitor cells.
