2 FIGURE 1 Histological staining of carcinoid tumors. Photomicrograph of H&E, CGA, and SYP staining of carcinoid tumors used for establishing TC1, TC2, and TC3 cell lines.

3 FIGURE 2 Expression of neuroendocrine markers. A, Immunohistochemistry staining demonstrating expression of CGA (red) and SYP (green) in carcinoid cell lines. B, Western blot demonstrating CGA (75 kDa) and SYP (43 kDa) expression in the established cell lines TC1, TC2, and TC3.

4 FIGURE 3 Typical carcinoid tumor cell lines in vitro growth characteristics. TC1, TC2, and TC3 cells were grown in vitro with or without 10% serum and proliferation was measured at various time points. Data shown is the mean fluorescence from the proliferation assay of triplicate samples +/- SEM.

5 FIGURE 4 Colony formation of lung carcinoid tumor cells in soft agar. TC1, TC2, and TC3 cells were plated in triplicate with control NSCLC A549 cells and nonneoplastic normal human bronchial epithelial cells (NHBEC) in soft agar. After 2 weeks of culture colonies greater than 50 microns in diameter were counted. Data shown is the mean of triplicate plates +/- SEM.

6 FIGURE 5 Pulmonary carcinoid xenograft tumor. A, Gross lung specimen from xenograft mouse showing large tumor nodule (arrow). B, Xenograft tumor (H&E, 10× and 40×) with comparison to the original patient tumor (H&E, 10× and 40×) demonstrating typical neuroendocrine features in both samples.
