Immunohistochemical analysis of LSR expression in normal urothelium and bladder cancer samples. The protein was located in the cytoplasm in >50% of the cancer cells. Original magnification, ×20 (all except C), ×10 (C). A: Normal bladder urothelium (21859-99); medium LSR expression. B: Negative control stain without primary antibody of T3 grade 3 tumor (6268-96). C-D: Ta grade 2 bladder tumor (4232-97); median LSR expression. E: T1 grade 2 bladder tumor (6018-98); weak LSR expression. F: T1 grade 3 bladder tumor (5248-02); medium LSR expression. G: T3 grade 3 bladder tumor (6268-96); weak LSR expression. H: T2 grade 3 bladder tumor (1719-00); weak, overall LSR expression in cytoplasm and nucleus.
