Figure Lengend Snippet: ( A – D ) Pancreatic CSCs, and cancer cell lines (PANC-1, AsPC-1, and MIA PaCa-2) were stably transduced with Gli-responsive GFP/firefly luciferase viral particles (pGreen Fire1-Gli with EF1, System Biosciences). Transduced CSCs and cell lines were treated with Mang-NPs (0–10 μM) for 24 h. Gli reporter activity was measured as we described . Data represent mean ± SD. *, # and % = significantly different from control, P < 0.05.

Figure Lengend Snippet: ( A ) Inhibition of pancreatic cancer growth and development in KPC mice. KPC mice were treated with Mang-NPs (20 mg/kg) for about 10 weeks. At the end of experiment, mice were sacrificed and pancreas weight was recorded. Data represent mean ± SD. * and # = significantly different from untreated control group, P < 0.05. ( B ) Pancreatic tissues from control and Mang-NPs-treated mice were fixed and stained with H & E. Tissue sections were visualized for the presence of PanIN (PanIN-1A, PanIN-1B, PanIN-2, and PanIN-3) lesions and PDAC. nd = not detected. ( C ) Liver metastasis. Liver tissues from control and Mang-NPs-treated mice were visualized for the presence of nodules. ( D ) Expression of stem cell marker, and pluripotency maintain factors in tumor tissues. Pancreatic cancer tissues from control and Mang-NPs treated mice were subjected to the Western blot analysis, and the expression of CD24, CD133, c-Myc, Nanog and Oct4 was measured. β-actin was used as a loading control. ( E ) Expression of components of Shh pathway in tumor tissues. Pancreatic cancer tissues from control and Mang-NPs treated mice were subjected to the Western blot analysis, and the expression of Gli1, Gli2, Patched1, Patched2, and Smoothened was measured. ( F ) Expression of Bcl2, XIAP and Cyclin D1 in tumor tissues. Pancreatic cancer tissues from control and Mang-NPs treated mice were subjected to the Western blot analysis, and the expression of Bcl2, XIAP and Cyclin D1 was measured. ( G ) Expression of E-cadherin, N-Cadherin, Slug, Snail, and Zeb1 in tumor tissues. Pancreatic cancer tissues from control and Mang-NPs treated mice were subjected to the Western blot analysis, and the expression of E-cadherin, N-Cadherin, Slug, Snail, and Zeb1 was measured.

Figure Lengend Snippet: Immunohistochemical staining of co-cultures with HRE, co-cultures with HUVEC and tri-cultures. (A–F) : pan-cytokeratin (green) was used to detect epithelial keratins in all cultures while mucin5AC (red) showed presence of mucus and goblet cells in all cultures containing HRE with BM-MSC (A,B) and HNF (E,F) as well as in HRE-co-cultures with ASC (C) but not in tri-cultures with ASC (D) (G–L) : claudin-1 (green) indicated tight junction formation in all HRE-cultures, and α-tubulin (red) could visualize cilia in all HRE-cultures with BM-MSC (G,H,S,T) and HNF (K,L,W,X) as well as in HRE-co-cultures with ASC (L,U) but not in tri-cultures with ASC (J,V) (M,O,Q) : CD31 staining confirmed presence of endothelial cells in co-cultures of HUVEC with BM-MSC (M) , ASC (O) or HNF (Q) (N,P,R) : pan-cytokeratin stained the epithelial cell layer on top of the fibrin gel while CD31 was used to detect endothelial cells and vascular-like structures in tri-cultures containing one of the supporting cell types: BM-MSC (N) , ASC (P) or HNF (R) ; DAPI (blue) was used to counterstain cell nuclei. Representative pictures are shown. Scale bar: 50 µm.
