简介：
Overview
This protocol helps establish patient-derived xenograft (PDX) models of anaplastic thyroid carcinoma (ATC) and head and neck squamous cell carcinoma (HNSCC), which better reflect tumor heterogeneity and molecular diversity. The technique is user-friendly and has a high success rate, making it suitable for various PDX models.
