Fig. 1From: Establishment and genomic characterizations of patient-derived esophageal squamous cell carcinoma xenograft models using biopsies for treatment optimizationEstablishment and histological characterization of PDX models from esophageal cancer patients. a Diagram of establishment of a stable PDX bank. b Decreasing latency with increasing passage. Line and error bars represent mean ± SD. p values were calculated using an unpaired two-tailed Student’s t test. *p < 0.05; **p < 0.01. c Representative histology of paired patient-PDX tumors. Slides were stained with H&E and images were captured at ×200Back to article page
