The first column (A1, B1, C1, and D1) shows prothoracic glands, the second (A2, B2, C2, D2) abdominal glands, and the third (A3, B3, C3, D3) gland schemes drawn based on own observations and previous depictions of Happ [14] and Eisner [13]. A1–A3, Tcas-ql VTGl (GT39) sense probes. B1–B3, Tcas-ql VTGl (GT39) antisense probes. C1–C3, Tcas-ql ARSB (GT62) antisense probes. D1–D3, Tcas-ql MRP (GT63) antisense probes. In the right lower corner of the panels in the first and second column, the expression was digitally magnified 4 times, with its original positions indicated by a square box or triangles within the same panel. Cell type 1 and cell type 2 were separately indicated in the abdominal glands, cell type 1 was zoomed in the right lower corner of the square, and cell type 2 in the left upper part of the square. Scale bars: 50 µm.
