Morphological changes of tendon stem cells growing on the scaffolds. (A) and (B) show cultured cells on the aligned and randomly-oriented scaffold, respectively. (C) and (D) High magnification of selected areas in (A) and (B) show the cell-matrix adhesion between cells and nanofibers. Arrow in (C) shows a filament-like structure on the aligned scaffold. (E) and (F) Confocal micrograph of CFDA-stained elongated tendon stem cells on the aligned and randomly-oriented scaffold, respectively. (G) Cell proliferation on the aligned and randomly-oriented scaffolds. Copyright 2010 Elsevier
