Regulation of Hepatic Stellate Cells and Fibrogenesis by Fibroblast Growth Factors

Figure 1

Structure of fibroblast growth factor receptors. Ig-I domain is present in α but not β variants (red). Splice variation in the Ig-III loop distinguishes b and c type receptors (purple). Acid box is present in AB variants (blue). AB: acid box, Ig: immunoglobulin-like domain, SP: signal peptide, TM: transmembrane domain, and TK: tyrosine kinase domain.
