Microscopic view of the hydrogel groups stained with HE. a, e The hydrogel only group showed the active infiltration of cells and the ingrowth of host tissue into the hydrogel (HE; original magnification, × 40, × 100). b, f Hydrogel combined with bFGF produced more abundant fibrous soft tissue extending from the surrounding tissues into the hydrogel compared to hydrogel alone (HE; original magnification, × 40, × 100). c, g Hydrogel combined with fibroblasts also produced invaginated host tissue and collagen matrices (HE; original magnification, × 40, × 100). d, h Hydrogel mixed with bFGF and fibroblasts induced the most abundant fibrous matrix (HE; original magnification, × 40, × 100)
