Polymer nanofibers for controlled cell growth. Scanning electron microscopy (SEM) images of (A) aligned PLLA nanofibers and (B) randomly-distributed PLLA nanofibers (reproduced from ref. 14 with permission, © Elsevier). SEM images of PANi-gelatin blend nanofibers with its averaged diameters of (C) 803 nm and (D) 61 nm. (reproduced from ref. 16 with permission, © Elsevier). Immunofluorescence images of neurofilaments (green) in NSCs (E) on aligned PLLA nanofibers and (F) on randomly-distributed PLLA nanofibers (reproduced from ref. 14 with permission, © Elsevier). Immunofluorescence images of actin filaments (red) and nuceli (blue) in myoblasts on the nanofibers with its averaged diameters of (G) 803 nm and (H) 61 nm (reproduced from ref. 16 with permission, © Elsevier).
