Cellular Interplay between Cardiomyocytes and Nonmyocytes in Cardiac Remodeling
Figure 3
A model for the regulation of fibroblasts by KLF5 during cardiac hypertrophy. The transcription factor KLF5 controls Igf1 and Pdgfa expression in cardiac fibroblasts. IGF-1 is a major cardiotrophic factor secreted from fibroblasts, and PDGF-A is primarily involved in mediating the migration and proliferation of fibroblasts.
