Figure Lengend Snippet: Fluorescence confocal microscopy was used to detect localization of SFRP2 (A, E, I) and FZD5 (B, F, J) in 2H11 (A–H) and SVR (I–L) cells. 2H11 cells were either untreated (A–D) or treated with 10 nM SFRP2 (E–H) for 1 minute. SFRP2 (green) FZD5 (red) were visualized using an FITC- or AlexaFluor546-labeled secondary antibody, respectively. Nuclei (blue) were identified using Hoeschst 33342. Merged images (C, G, K) showing the co-localization of SFRP2 and FZD5 (yellow) at the surface of SFRP2-treated 2H11 cells (G), at the surface SVR cells which highly express endogenous SFP2 (K), but not at the surface of untreated 2H11 cells (C). Controls were treated with secondary antibody only, with the primary antibody omitted (D, H, I). Scale bar in A, E and I represents 30μm.

Figure Lengend Snippet: The vertical scatter plot shows individual Pearson’s correlation coefficients with the mean of the coefficients and standard error of the mean (n = 9 cells from at least four fields for all samples). Analysis indicates that in 2H11 cells, a pool of SFRP2 and FZD5 colocalize. This phenomenon is rapidly amplified by the addition of exogenous SFRP2 and reaches the levels of colocalization observed in SVR cells, which express sustained endogenous levels of SFRP2. Difference between 2H11 control and 2H11 exposed for one minute to exogenous rhSFPR2 was significant (two tailed t-test; p = 0.0003).

Figure Lengend Snippet: Graphic representation of rhSFRP2 and rhWnt5a binding to FZD5-Fc showing changes in 450 nm optical density (OD450) as a function of the log of ligand concentrations. To do this, A microplate solid phase protein binding assay was performed using a concentration range of his-tagged recombinant human SFRP2 and Wnt5a from 24nM – 1500nM (x axis). The experiment was repeated twice for a total of n = 6. Kd, EC50 and Hill coefficient were calculated and compared for SFRP2 and Wnt5a binding to FZD5.
