In the article titled “Evaluation of carcinoma-associated fibroblasts in oral squamous cell carcinoma: a potential role for cathepsin K”, published on pages 208-215, Issue 4, Volume 14 of Tanta Dental Journal [1], [Table 2] has been incorrectly published. The table number is correct. The correct [Table 2] and its correct legend is mentioned below:
Table 2: CTSK expression by tumor cells and stromal CAFs in different OSCC grades assessed by Mann-Whitney U test

[Figure 1], [Figure 2], [Figure 3], [Figure 4] and [Figure 5] have been incorrectly published. The correct [Figure 1], [Figure 2], [Figure 3], [Figure 4] and [Figure 5] and their legends are mentioned below:
Figure 1: Phase contrast microscope images of confluent cell cultures: a) Normal human fibroblast cell line (BJ) shows elongated morphology with bipolar or multipolar outline. b) OSCC cell line (SCC-9) exhibits polygonal shapes with more regular dimensions (a and b, original magnification ×200).

Figure 2: Immunohistochemical staining for α-SMA (a, c, e) and CTSK (b, d, f) in well differentiated OSCC (×400). (b) Weak CTSK expression in the cytoplasm of invading tumor islands as well as within stromal CAFs. Moderate CTSK expression is evident in (d) and (f) in tumor cells. (f) Strong CTSK expression by scattered peritumoral CAFs.

Figure 3: Immunohistochemical staining for α-SMA (a, c, e) and CTSK (b, d, f) in moderately differentiated OSCC (×400). Tumor epithelial cells show weak (b), moderate (d) and strong (f) cytoplasmic CTSK expression. Peritumoral CAFs exhibit moderate (b, d) and strong (f) CTSK immunostaining. Positive staining is noted in chronic inflammatory cells (black arrow) (d).

Figure 4: Immunohistochemical staining for α-SMA (a, c) and CTSK (b, d) in poorly differentiated OSCC (×400). Moderate CTSK expression is observed in the cytoplasm of tumor cells as well as in stromal CAFs (b). Strong cytoplasmic CTSK immunostaining is evident in both tumor cells and scattered peritumoral CAFs (d).

Figure 5: (a) Invading front of well differentiated OSCC with α-SMA immunostaining highlighting bands of CAFs as well as internal control blood vessels (black arrowheads) (×400). (b) The same previous fields shows moderate CTSK expression in tumor cell cytoplasm and strong expression in stromal CAFs (×400).
