FasL protein expression by bladder TCC cell lines. Immunocytochemical staining was performed using the anti-FasL A11 mAb. The 1207 (A) and 1512 (B) primary culture TCC cell lines, obtained from two FasL-expressing tumors, show a membrane immunostaining. C: T24 bladder cell line is characterized by a predominant granular and cytoplasmatic immunostaining. D: RT112 bladder cell line is negative. Immunostaining is in brown. Counterstain with hematoxylin. Original magnifications, ×40 (A–D).
