The larger organelles, such as the
nucleus and vacuoles, are easily visible with moderate magnification (although sometimes a clear view requires the application
of chemicals that selectively
stain parts
of the
cells); they were among the first biological discoveries made after the invention
of the microscope.

staining indicates the cortical marker CTIP2, the red
stain is the neuronal marker TUJ1, and the blue

nuclei of the
cells.

DDX3 was strongly immunolocalized in the
nucleus and less intensively in the cytosol
of squamous
cells in normal skin, but the nuclear
staining was lost or dramatically decreased in cutaneous SCC.

of GII revealed strong positive expression
of Cyclin D1 in invasive ductal epithelial

nuclei of the
cells were also
stained to differentiate between neurons and glia, allowing researchers to then count the
cell nuclei that belong to neurons.
