Figure 4From: Apoptotic function of tumor-associated antigen RCAS1 in oral squamous cell carcinoma Representative results for Annxin-V positive ratio of K562 cultured with OSCC cell lines. Apoptosis rates for K562 cells gradually increased by E/T ratios and culture periods in all conditions of co-culture for each OSCC cell lines. Apoptosis of K562 was more induced in the co-culture with SQUU-B cells than with the other 3 OSCC cell lines.Back to article page
