Fig. 2. WTPDX recapitulate histologic and molecular phenotypes of primary tumors.

Fig. 2

Paired favorable-histology, triphasic primary Wilms tumor (WT) a and WTPDX b corresponding to case KT-45 are shown in the top two rows. WTPDX b maintain the epithelial, stromal, and blastemal triphasic histology of primary WT a. WTPDX maintain blastemal SIX2 expression (middle) and WT1 expression (right) b compared with the primary WT a. Paired unfavorable-histology (diffuse anaplasia) WT c and WTPDX d corresponding to case KT-60. WTPDX d maintain the hyperchromatic, large nuclei, and atypical multipolar mitoses (arrows) of the primary WT c. WTPDX d retain p53 immunostaining that is characteristic of tumors with TP53 missense mutations. Scale bar = 100 μm.
