(A) Colon L1 DRG cells were labeled with DiI (red). (B)CBS positive cells were shown in green. (C) TRPV1 positive cells are shown in blue. (D) Merge of double labeling of DiI and CBS. (E) Merge of TRPV1-positive staining and DiI labeling. (F) Merge of TRPV1-positive staining and CBS labeling. Bar = 50 μm.Back to article page
