Collection of morphological different mature endothelial-like cells from one healthy donor. Cells (A,B) represent large cells with low N/C ratio and cytoplasmic pleomorphism. Cells (A,B) measures 34.5 µm in length 21.4 µm, respectively. This endothelial-like cell type has similarities to activated tip cells. Cells (C,D) represent smaller cobblestone-like cells with higher N/C-ratio and measure 10.4 µm and 10.7 µm in length (largest diameter), respectively. This endothelial-like cell has similarities to quiescent phalanx cells. The nuclei of all cells show similarities in relative high density, morphology and shape with a size ranging between 7.4 µm to 9.4 µm. The nuclei chromatin structure is amorph and high in fluorescence intensity. White scale bar is 10 µm.
