FIG. 10.

Cell source and Berlin blue. (A) CM-Dil was tracked with weak red fluorescence in the nanoparticle with magnet group (scale bar=100 μm). (B) Cell nuclei in the center corneal endothelium were stained by mouse anti-human nuclei monoclonal antibody with dark brown in the nanoparticle with magnet group (scale bar=50 μm). (C) The Berlin blue staining for iron revealed no iron in the endothelium in the nanoparticle with magnet group (scale bar=50 μm). (D) The Berlin blue staining was positive for the CD34 nanoparticles showing blue color (scale bar=50 μm). Color images available online at www.liebertpub.com/scd
