Together, these results suggest that ALDH1, CD44, CD10, and CD24 are highly expressed in salivary gland mucoepidermoid carcinoma when compared to normal salivary gland and that expression of ALDH1, CD10, and CD24 may be differentially regulated in more aggressive cell types. The gene discussed is ALDH1A1; the disease is salivary gland mucoepidermoid carcinoma.
