(C) Western blot analysis of whole cell lysates of GI-101A and its derivatives (GI-LM2, GI-LM2C, GI-LM2G) on estrogen receptor (ER) expression. Figure S2 (A) Immunofluorescence staining of GI-LM2C (upper row) and GI-LM2G spheres (lower row) for Gal3 (red), E-cadherin (CDH1, green), and vimentin (gray). (B) Immunofluorescence staining of the same cell lines for cytokeratin 18 (red) and vimentin (green). Counterstaining with DAPI (blue) was used to visualize cell nuclei. Figure S3 (A) Flow cytometric analysis shows that Gal3-positive populations (in red) of the same cell line consistently contain a lower BCSC pool than Gal3-negative populations (in green). (B) Correlation of Gal3 with CD24 and EpCAM expression is listed in a table. Figure S4 (A) Brightfield pictures of spheres in low magnification. Figure is related with Fig. 3a. (B) Sphere-formation assay and its quantification of GI-101A, GI-101A after knockout of Gal3 (GI-101A-G) as well as derivatives GI-LM2C and GI-LM2G. (C) Western blot of whole cell lysates of GI-LM2C and GI-LM2G for Wnt targets Axin2 and Tcf4. Loading control β-actin was used. The same membrane is used in Fig. S1C.
