Cancer cell plasticity defines response to immunotherapy in cutaneous squamous cell carcinoma - Nature Communications

Identification, functional insights and therapeutic targeting of EMT tumour states - Nature Reviews Cancer

The authors also discuss the implications of this knowledge for pharmacologically targeting epithelial-to-mesenchymal transition to overcome therapy resistance.
