Salivary gland stem/progenitor cells (SSPCs) hold significant potential for regenerative medicine, especially for patients suffering from salivary gland dysfunction due to various causes such as radiation therapy, Sjögren's syndrome, and aging. This review provides a comprehensive overview of SSPCs, including their characteristics, isolation, culture techniques, differentiation pathways, and their role in tissue regeneration. Additionally, we highlight recent advances in cell- and tissue-based therapies, such as SSPC transplantation and bioengineered organ replacements. The challenges in translating SSPC research into effective clinical therapies are also discussed, alongside proposed solutions and future research directions.
