Fiber-Hydrogel Scaffold for Sustained Non-viral Drug and/or Gene Delivery

(A) Scanning electron microscopy images of cross-section of scaffold showing aligned electrospun fibers and collagen matrix. Scale bar represents 1 mm. (B) Magnified image of aligned electrospun fibers (white arrow indicates the direction of fiber alignment, which points out of the page at ∼45°). Scale bar represents 100 μm. (C) Cumulative release of miR and NT-3 over time. (D) Mass loss of scaffold over time. Data are represented as mean ± SD.
