Expression of Nodal protein in retinoblastoma. a. Strong, diffuse expression of Nodal in retinoblastoma cells, with two vessels (asterisks) largely negative for the protein on immunohistochemical analysis serving as internal negative controls. b. Strong expression of Nodal in the periphery of a retinoblastoma. c. In the tumor shown in b, Nodal expression was only moderate in the center of the lesions, and was most prominent in the neoplastic rosettes (asterisks).
