Secret world of cells
Life, but not as you know it: the microscopic world of cells viewed under a microscope.
Fluorescent brain cells
Fluorescence image of brain cells created by stitching together six images collected at 40x magnification.
Photomicrograph showing the different components of the rat cerebellum, including Purkinje neurones in green, glia (non-neuronal cells) in red, and cell nuclei in blue.
Human eye with conjunctivitis
Confocal micrograph of a mast cell in a human eye with conjunctivitis. This image shows a single mast cell invading conjunctival tissue in response to an inflammatory agent or pathogen.
Adult mouse hippocampus, a region of the brain involved in learning and memory, showing reactive astroglia (pale yellow) that have proliferated and enlarged in response to neuronal activity over time.
Human gall bladder
Gallbladder wall of a human patient with gallstones. The duct (clear zone, centre) is lined by highly polarised epithelial cells with dark nuclei at the base.
Thale cress leaf
Confocal micrograph of thale cress (Arabidopsis thaliana) seedling leaf with stomata (yellow mouth-like structures).
Digital multi-colour immuno-fluorescence microscopy and phase contrast image of fibroblast cells – which play an important role in wound healing in animal tissue – stained with various antibodies.
Embryonic stem cells
Molecules (red stains) such as proteins delivered into aggregates of embryonic stem cells via biodegradable polymer microspheres.
Rat cerebral cortex
Confocal micrograph of a rat cerebral cortex with astrocytes’ (yellow) endfeet wrapping around blood vessels (red).
Mouse kidney cells
This image showing the cells inside a mouse kidney was obtained using 15 femtosecond (quadrillionths of a second) laser pulses.
A 3-D view of a model protocell (a primitive cell) approximately 100 nanometers in diameter.
Red blood cells
This image of erythrocytes (red blood cells) was taken with a scanning electron micrograph using false colour.
