Fig. 2From: Tumor-associated macrophages correlate with the clinicopathological features and poor outcomes via inducing epithelial to mesenchymal transition in oral squamous cell carcinomaCD68 and CD163 expression was examined in tumor cells by immunohistochemistry. High expression of CD68 a1, a2, a3 and low expression of CD163 (b1, b2, b3) was found in tumor cells. Low expression of CD68 (c1, c2, c3) and high expression of CD163 (d1, d2, d3) was found in tumor cells. (a1-d1, 100×; a2-d2, 200×; a3-d3, 400×)Back to article page
