Cultured chicken embryonic cardiomyocyte transfected with GFP control vector in the nucleus, stained with alpha-actinin at the Z-lines in red and Tropomodulin1 (at the pointed ends of the actin filame...

Confocal micrograph showing the development of motor neurons in the mouse forelimb at 11.5 days post coitum. The transgenic mice expresses a transgene of the Hb9 gene containing a genetic insert of th...

Zebrafish embryo showing the alignment of cells involved in the formation of the neural tube, which will become the spinal cord and brain.

Differentiated human induced pluripotent stem cells (iPSCs) following differentiation protocol. Cell nuclei were stained with DAPI (blue), nestin (red) and beta3-tubulin/Tuj1 (green). Note the fate de...

Blood vessels and astrocytes in aging rat retina, confocal imaging, 40x. Blood vessels are shown in blue; astrocytes (supportive cells of the nervous system) are mostly in red. As organisms age, ...

Eye of a 24 hr zebrafish embryo stained for paxillin (green) and laminin (red). Images made available by Mark Cooper thru The Zebrafish A Living Laboratory.

Human umbilical vein endothelial cells stained initially for nuclei with DAPI (blue) and for vascular endothelial cadherin (red).

Two interphase cells with immunofluorescence labeling of actin filaments (purple), microtubules (yellow), and nuclei (green). This image won first place in the Nikon 2003 Small World photo competition...

A confocal image of breast cancer cells in culture. The cell to the lower left is dying.

A confocal image of dividing keratinocyte cells labelled with mitotracker (red), tubulin (green) and nuclei (Dapi-blue). Cells were part of a study of the effect of Papilloma viruses in keratinocytes.
