1. A chimeric antigen receptor (CAR) comprising:
i) at least one antigen specific targeting region comprising a fibronectin type 3 (FN3) domain polypeptide;
ii) a transmembrane domain; and
iii) an intracellular signaling domain,
wherein the CAR further comprises an extracellular spacer domain
wherein the least one antigen specific targeting region comprises an amino acid sequence set forth in SEQ ID NO: 33.
