Oral Diseases (2010) doi: 10.1111/j.1601-0825.2010.01723.x Hyposalivation underlying xerostomia after radiotherapy is still a major problem in the treatment of head and neck cancer. Stem cell therapy may provide a means to reduce radiation-induced hyposalivation and improve the quality of life of patients. This review discusses the current status in salivary gland stem cell research with respect to their potential to attenuate salivary gland dysfunction. Knowledge on the embryonic development, homeostasis and regeneration after atrophy of the salivary glands has provided important knowledge on the location of the salivary gland as well as on the factors that influence proliferation and differentiation. This knowledge has helped to locate, isolate and characterize cell populations that contain the salivary gland stem cell, although the exact tissue stem cell is still unidentified. The role that stem/progenitor cells play in the response to radiation and the factors that can influence stem/progenitor induced proliferation and differentiation are discussed. Finally, the mobilization and transplantation of stem cells and supportive cells and their potential to attenuate radiation-induced salivary gland damage are discussed. Based on the major advances made in the field of stem cell research, stem cell-based therapy has great potential to allow prevention or treatment of radiation-induced hyposalivation.

Accidental or medical radiation exposure of the salivary glands can gravely impact oral health. Previous studies have shown the importance of Tousled-like kinase 1 (TLK1) and its alternate start varia...
Mesenchymal stromal cells (MSCs) have been used to minimize and repair radiation-induced normal tissue injury in the intestine, salivary gland, liver, skin, lungs and cardiac muscle. This study invest...
The aim of this study was to examine the effects of melatonin on ionized radiation-induced salivary gland damage using an experimental model.
Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy and is successfully treated by surgery and radiation. However, some patients have recurrent tumours and in these cases, few ...
The salivary gland is a complex, secretory tissue that produces saliva and maintains oral homeostasis. Radiation induced salivary gland atrophy, manifested as "dry mouth" or xerostomia, poses a signif...
RATIONALE: Moving a salivary gland out of the area that will undergo radiation therapy may protect the gland from side effects of radiation therapy and may prevent xerostomia (dry mouth). ...
Standard therapy for high-risk or locally advanced salivary gland malignancies is surgery followed by postoperative radiation therapy. Retrospective studies have shown the superiority of c...
Therapeutic irradiation to the head and neck for cancer damages salivary glands present in the radiation field. Despite long recognition of radiation-induced salivary hypofunction, and th...
The current study aims to assess the safety and feasibility of the injection of autologous adipost tissue derived MSCs on radiation-induced salivary gland hypofunction and xerostomia in he...

Calculi occurring in a salivary gland. Most salivary gland calculi occur in the submandibular gland, but can also occur in the parotid gland and in the sublingual and minor salivary glands.
A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth.

The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
Glands that secrete SALIVA in the MOUTH. There are three pairs of salivary glands (PAROTID GLAND; SUBLINGUAL GLAND; SUBMANDIBULAR GLAND).
