Expression of CD44 and SALL4 in Leukoplakia and Oral Squamous Cell Carcinoma.

CD44 and SALL4 are markers of stemness and expressed in cancer stem cells (CSCs). Their deregulated expression was seen in various tumors and has been correlated with clinical severity. We evaluated immunohistochemical expression of CD44 and SALL4 in leukoplakia and oral squamous cell carcinoma (OSCC).
