Figure Lengend Snippet: General overview of the cellular composition of the tissue capsule formed around implanted rods. (A) vWF staining for vascularization, (B) Ki67 for proliferating cells, (C) α-SMA for myofibroblast, (D) desmin for contractile smooth muscle cells, and (E) vimentin for fibroblast. The tissue capsules are mainly composed of fibroblasts and myofibroblasts. There are barely contractile smooth muscle cells present. All tissue capsules are well vascularized. Scale bar represents 50 μm.

Article Snippet: Adult rat dermal fibroblasts (aRDF, #R2320, ScienCell Research Laboratories) were cultured with a basic culture medium comprising DMEM (Gibco), fetal bovine serum (10%, Lonza), l -glutamine (2 mM, Gibco), and penicillin (100 U/mL) and streptomycin (100 mg/mL, Gibco). aRDF were expanded at an initial seeding density of 5000 cells/cm 2 in a culture medium and refreshed every 2–3 days.

Figure Lengend Snippet: (A) The number of cells (per 1000 μm 2 ) positively stained for α-smooth muscle actin is depicted, a differentiation marker for myofibroblasts. (B) The number of cells (per 1000 μm 2 ) stained positively with the desmin antibody is depicted, which stains the intermediate filament protein expressed in contractile smooth muscle cells. (C) The number of cells (per 1000 μm 2 ) positively stained for vimentin is depicted, which is an intermediate filament expressed in fibroblasts. The expressions of myofibroblasts, contractile smooth muscle cells, and fibroblasts were observed in the following conditions: control (no release), burst release (TGF-β1 and PDGF-BB), single layer-by-layer release (TGF-β1, PDGF-BB, and IGF-1), and dual layer-by-layer release (TGF-β1/IGF-1 and PDGF-BB/TGF-β1). Data was analyzed using ordinary one-way ANOVA followed by a post hoc analysis using Tukey’s test, and * indicates significance of P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001, and **** P ≤ 0.0001.
