“…Based on previous reports of FGF expression patterns, we extended our analysis to FGF1,2,3,5,8,9 and 15 to assay their pairwise interactions with FGFR1b, 1c, 2b, 2c, 3b, 3c and 4 (Chow and Lang, 2001;de Iongh and McAvoy, 1993;Kitaoka et al, 1994;Lovicu and Overbeek, 1998;Martinez-Morales et al, 2005;McWhirter et al, 1997;Nguyen and Arnheiter, 2000;Vogel-Hopker et al, 2000;Zhao et al, 2001). This includes all the FGF and FGFR variants known to be present during early eye development.…”
