These data are in line with our previous research demonstrating a loss of IL34 in CIN, cervical cancer [18], in head and neck squamous cell carcinomas, and a murine model of HPV‐mediated epithelial hyperplasia [59, 60, 61], and spatially defines the restricted loss of IL34 to the neoplastic regions, while maintaining signalling in adjacent tissue regions. Here, IL34 is linked to cervical squamous intraepithelial neoplasia.
