[Human mucoepidermoid carcinoma MEC-1 cells induced differentiation by HMBA]

Mucoepidermoid carcinoma is the most common malignant tumor of salivary glands. In this report, we used hexamethylene bisacetamide (HMBA) as a inducer to induce human mucoepidermoid carcinoma cell line MEC-1 cells to differentiate. The growth kinetics, morphological changes and DNA contents of the cells were investigated. The results showed that HMBA-treated MEC-1 cells tend to become mature cells, implying that HMBA can induce differentiation of MEC-1 cells in vitro.
