If we relate our findings to those of others, we can acknowledge research showing that oral squamous cell carcinoma cell lines other than HSC2 and TR146 are a source of chemokines, e.g., IL1 enhanced CXCL1 expression in the dysplastic oral keratinocytes and cell lines TW2.6 and OC3 [36]. Here, CXCL1 is linked to oral cavity squamous cell carcinoma.
