Reinforcing the specialized nature of the inflammation, we interrogated whether our mouse BCC scRNA-Seq datasets from our defined Ptch1+/−;p53f/f;K14Cre-ER;RFPf-s-f BCC tumor model that we found typically models many aspects of clinical BCCs34,35 also possessed BIT-associated inflammation. The gene discussed is SIRPA; the disease is skin basal cell carcinoma.
