Evaluation of relevant tendon healing growth factors. (a) Growth factors present in amniotic membranes. Mean ± standard deviation reported; n = 9 for HSAM, n = 7 for dACM. * denotes p < .05; **** denotes p < .0001. (b) Growth factor concentration in conditioned media. Mean ± standard deviation reported; n = 4 for both HSAM and dACM. aFGF, acidic fibroblast growth factor; bFGF, basic fibroblast growth factor; dACM, dehydrated amnion/chorion membrane; HSAM, hypothermically stored amniotic membrane; IGF‐1, insulin‐like growth factor I; PDGF‐BB, platelet‐derived growth factor‐BB; TGF‐β1, transforming growth factor beta‐1
