  • Antidepressant drug blocking dopamine transporter protein
  • Cellular architecture of normal human skin imaged by whole mount tissue microscopy. Human skin has a rich network of white blood cells (specifically dendritic cells, T cells and macrophages) which form sheaths around blood vessels. This image was taken directly beneath the junction that joins the dermal and epidermal layers of the skin (dermo-epidermal junction). At this level, the capillary network (stained for CD31; red) is visualised against a lawn of autofluorescent dermal papillae (finger-like projections of the dermis; green) scattered with dendritic cells (stained for CD11c; green) and macrophages (stained for LYVE-1; blue). This normal cellular architecture is grossly disrupted in diseased skin (see related images). Scale bar (white) represents 200 micrometres.
  • Human heart (aortic valve) tissue displaying calcification
  • Multi-sized beads (constellation stained), fluorescence
  • Breast cancer cell spheroid, SEM
  • Westringia fruticosa 'Variegata'
  • Hoverfly eye
  • Healthy adult human brain viewed from the side, deep dream
  • Butterfly wing scales
  • Adenovirus
  • Rhodiola rosea L. Crassulaceae Golden root, roseroot Distribution: Arctic, Eastern North America, mountains of central Asia. Herbalists regard it as having curative properties for diseases as diverse as cancer, influenza, depression and other conditions. It has not been licensed for use in manufactured herbal medicines in the UK. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Apoptosis
  • Healthy adult human brain viewed face on, tractography
  • Raynaud's Phenomenon
  • Human heart (aortic valve) tissue displaying calcification
  • Human heart (aortic valve) tissue displaying calcification
  • Mammary gland, 4 day-old mouse
  • Cellular architecture of normal human skin imaged by whole mount tissue microscopy. Human skin has a rich network of white blood cells (specifically dendritic cells, T cells and macrophages) which form sheaths around blood vessels. In this image, blood vessels (string-like structures stained for CD31; green), lymphatic vessels (ribbon-like structures stained for LYVE-1; blue) and T cells (stained for CD3; red) can be seen. T cells are only found around dermal blood vessels. Macrophages (stained for LYVE-1; blue) are also present. This normal cellular architecture is grossly disrupted in diseased skin (see related images). X10 magnification. Scale bar (white) represents 200 micrometres.
  • Mouse Ear Skin
  • Doctor in scrubs making notes
  • Borago officinalis (Borage, Star flower)
  • Pancreatic cancer cells grown in culture, SEM
  • Partners in crime - chloroplasts and mitochondria
  • Fractal patterns in a Bacillus subtilis biofilm, LM
  • Ambulance on route to an emergency call out, UK.
  • Raynaud's Phenomenon
  • Diatom frustule, SEM
  • Cellular architecture of normal human skin imaged by whole mount tissue microscopy. Human skin has a rich network of white blood cells (specifically dendritic cells, T cells and macrophages) which form sheaths around blood vessels. In this image, T cells (stained for CD3; red) dendritic cells (stained for MHC class II; green) and macrophages (stained for LYVE-1; blue with some cells showing a tinge of green) can be seen. Cell nuclei have been stained with DAPI (grey). This normal cellular architecture is grossly disrupted in diseased skin (see related images). X20 magnification. Scale bar (white) represents 100 micrometres.
  • Mouse embryo head viewed from the front
  • ATP synthase is an enzyme that creates the energy storage molecule adenosine triphosphate (ATP). ATP is simply the energy used by cells of most organisms
