DDR2 and Hepatic fibrosis: This result was in agreementwith previous studies, showing that the presence of type I collagenexerts an enhancing effect on cardiac fibroblast proliferation.45 HCFs cultured on PCL/polyDOPA/C1F membranesalso showed an enhanced expression of DDR2, a collagen-activated receptor,that has been found to play a pivotal role in promoting cell proliferation,in different pathological conditions associated with exacerbated ECMdeposition, such as skin wound healing, liver fibrosis, and even tumorprogression.46
