Considering that some of the STAB1 signature genes are typically expressed by foetal Mɸ (such as STAB1, FOLR2, SLC40A1, MERTK, GPR34 and F13A1)54, we wanted to explore if further transcriptional commonalities exist between tumour-originating STAB1 + Mɸ and Mɸ isolated from human foetal lung. The gene discussed is F13A1; the disease is neoplasm.
