Fig 1 Direct fluorescent staining of endothelial progenitor cells (EPC) from fresh mononuclear cells (MNCs) (I) and cryopreserved mononuclear cells (II). (A) Isolectin B4 staining. (B) Acetylated low-density lipoprotein labeled with 1,1′-dioctadecyl-3,3,3′-3′-tetramethylindo-carbocyanine perchlorate staining. (C) 4′,6-diamidino-2-phenylindole dihydrochloride staining. (D) Merged images of all three staining techniques.

Fig 2 Proliferation activity in cell culture media. White column, endothelial progenitor cells from fresh mononuclear cells; black column, endothelial progenitor cells from cryopreserved mononuclear cells. Asterisk and sharp indicate significance compared with white and black columns of control, respectively.
