Activation of Wnt/β-catenin signaling is critical for the tumorigenesis of choroid plexus

Choroid plexus (ChP) is the secretory epithelial structure located in brain ventricles. Choroid plexus tumors (CPTs) are rare neoplasms predominantly occurring in young patients with intensified malignancy in children. CPT treatment is hindered by insufficient knowledge of the tumor pathology and limited availability of valid models.
