Figure 2From: Tumor grafts derived from patients with head and neck squamous carcinoma authentically maintain the molecular and histologic characteristics of human cancersPDXs maintained the histologic characteristics of the parent tumors from which they were derived. Hematoxylin & eosin staining (200 x) of patients’ original tumor (F0) and PDX tumors demonstrated similar histologic characteristics, but with more homogeneity. Perineural invasion (white arrow) matched that of the parent tumor (HOSC10).Back to article page
