Immunofluorescence analysis of cultured human keratinocytes derived from pterygium explants labelled with anti-VEGF (red label at nuclear level %) and anti-VEGF-R1 (green label located both in the nucleus and cytoplasm %). Original magnification: 100x. The observations were carried out using a ZEISS Axioskop light microscope equipped with a Coolsnap video camera to acquire images analysed with the MetaMorph 6.1 Software (Universal Imaging Corp, Downingtown, PA). Images displayed are representative of 3 independent experiments.
