SDC1 and neoplasm: Tumor cell clusters with well-defined WGA staining at cell boundaries were observed whereas other clusters showed a much more diffuse WGA staining pattern, marked by prominent cytoplasmic E-cadherin, β-actin, and syndecan-1 staining [20]. In a study by Sinha et al., the OSCC was treated with different concentrations of AGG (0.1, 0.5, and 1 μg/mL).
