Stress or injury induces cellular plasticity in salivary gland acinar cells.

ABSTRACT: Salivary gland function is severely disrupted by radiation therapy used to treat patients diagnosed with head and neck cancer and by Sjögren's syndrome. The resulting condition, which results in xerostomia or dry mouth, is due to irreversible loss of the secretory acinar cells within the major salivary glands. There are presently no treatments for the resolution of xerostomia. Cell-based approaches could be employed to repopulate acinar cells in the salivary gland but investigations into potential therapeutic strategies are limited by the challenges of maintaining and expanding acinar cells in vitro. We investigate the encapsulation of salivary gland cell aggregates within PEG hydrogels as a means of culturing secretory acinar cells. Lineage tracing was used to monitor the fate of acinar c
