Retina blood vessels and nerve cells. Confocal light micrograph of the retina, the light-sensitive membrane that lines the back of the eyeball. The tissue has been fluorescently stained. Ganglion cells (orange) receive visual information from photoreceptors beneath this surface, which is relayed to the brain by optic nerve fibres (red). Glial cells (green) offer structural support to the nerve cells. Blood vessels (blue) form branching networks across the retina to supply it with oxygen and nutrients. Magnification: 160x when printed 10 centimetres across.

Retina cells. Fluorescent light micrograph of cells in the retina, the light-sensitive membrane that lines the back of the eyeball. A blood vessel runs from left to right, and numerous other branches are seen. The tissue has been tagged with fluorescent markers specific to certain proteins. The green marks actin filaments that ensheath the vessel and help modulate blood flow by constriction and relaxation. Red marks for red blood cells. Magnification: x200 when printed 10 cm wide.

Purkinje cells in the cerebellum. Fluorescent light micrograph of Purkinje cells (green) in the cerebellum of the brain. Purkinje nerve cells have a flask-like body from which numerous highly branched dendrites extend. They are found in the grey matter (cortex) of the cerebellum, at the boundary between the granular layer (blue red) and the molecular layer (red green). The dendrites relay signals to the cell body, which passes them on through its single axon (green) in the granular layer. The cerebellum is a structure at the base of the brain that plays an important role in motor control, sensory perception and learning. Magnification: x380 when printed 10cm wide.

Small intestine lining. Light micrograph of a section through villi (finger-like projections) in the healthy mucosal lining of the jejunum, the middle section of the small intestine. Villi are projections that increase the surface area for the absorption of food.

Liver tissue. Fluorescence deconvolution micrograph of a section through liver tissue, showing a central vein (round), hepatocyte cells (red), cell nuclei (blue dots), and a small amount of connective tissue (green).

Intestinal villi. Fluorescent deconvolution light micrograph of a section through villi (round) in the wall of the jejunum of the small intestine. Villi are finger-like projections that greatly increase the surface area of the intestine for the absorption or nutrients. Magnification: x800, when printed 10 centimetres wide.

Cerebral cortex nerve cells. Light micrograph of a section through neurones (nerve cells, black) in the cerebral cortex of a human brain. Branching processes (dendrites) receive impulses from other nerve cells and pass them to the cell body. Each cell body also has an axon through which it relays nerve impulses to the dendrites of other neurones. Neurones allow information to be received, interpreted and relayed around the body. The grey matter of the cerebral cortex forms the outer layer of the brain that is responsible for conscious thought, memory and language.

Plasmacytoma. Light micrograph (LM) of a section from a nasal plasmocytoma. Plasmacytoma (purple tissue) of the head and neck region is a rare malignant tumour comprising approximately 3% of all plasma cell tumours. Approximately 80-90% of extramedullary (outside the bone marrow) plasmacytomas involve the mucosa-associated lymphoid tissue of the upper airways, 75% of these involve the nasal and paranasal regions. Radiotherapy generally provides excellent local and often durable control of the plasmacytoma. However, there is a risk that plasmacytomas may recur or progress to myeloma. Magnification: x80 when printed at 10 centimetres wide. Human tissue.

Cerebral cortex nerve cells. Light micrograph of a section through neurones (nerve cells, black) in the cerebral cortex of a human brain. Branching processes (dendrites) receive impulses from other nerve cells and pass them to the cell body (round, two at upper right). Each cell body also has an axon through which it relays nerve impulses to the dendrites of other neurones. Neurones allow information to be received, interpreted and relayed around the body. The grey matter of the cerebral cortex forms the outer layer of the brain that is responsible for conscious thought, memory and language. Magnification unknown.

Varicosed vein. Light micrograph of a section through a varicosed saphenous vein in the lower leg, showing its thickened wall. Varicose veins are veins that become swollen, lengthened and coiled. They form due to defective valves in the superficial veins, commonly in the legs, and may require surgical removal.

Winged spindle tree stem. Polarised light micrograph of a cross section through the stem of a young winged spindle tree (Euonymus alatus). This section shows the outer dry, corky region of the stem. Magnification: x200 when printed 10 centimetres wide.

Mycoplasma. Composition coloured scanning electron micrograph (SEM) of a dendritic cell infected with Mycoplasma pneumoniae (green). Mycoplasmas are bacteria that lack a cell wall. Without a cell wall, they are unaffected by many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. They can be parasitic or saprotrophic. Several species are pathogenic in humans, including M. pneumoniae, which is an important cause of atypical pneumonia and other respiratory disorders. They commonly occur as parasites and pathogens (disease-causing organisms) in humans and other animals. They are the smallest bacteria known, and also have a very small genome (total genetic material). Magnification:x4000 wh...

Biology and Medical researchers who run Polymerase Chain Reaction (PCR) procedures will love this funny graphic that says " Pipette Cry Repeat". The artwork depicts a multichannel pipette, teardrops, and an agarose electrophoresis gel. Biotechnologists who study Microbiology, Genetics, Histology, Immunology, Molecular & Cellular Biology and who conduct DNA sequencing, cloning, and gene editing techniques will love this great gift design!

Adipose stem cells. Fluorescence light micrograph of human stem cells derived from adipose (fat) tissue. Nestin protein filaments are red; membrane cofactor protein is green; and cell nuclei are blue. Magnification: x63 when printed 10 centimetres wide.
