Red arrows indicate secreted lamellar bodies, and green arrows indicate lamellar bodies in the cytoplasm. Scale bar = 200 nm. In cell biology, lamellar bodies (otherwise known as lamellar granules, membrane-coating granules (MCGs), keratinosomes or Odland bodies) are secretory organelles found in type II alveolar cells in the lungs, and in keratinocytes in the skin.
Microscopic image of the epidermis, which constitutes the outer layer of skin, shown here by the white bar Microscopic image showing the layers of the epidermis. The stratum corneum appears more compact in this image than above because of different sample preparation.
The red object in the lower left is a scale bar indicating relative size. Approximately 10× micrograph of a doubled die on a coin, where the date was punched twice in the die used to strike the coin. A micrograph is an image, captured photographically or digitally, taken through a microscope or similar device to show a magnified image of
Top: MRM image of mouse muscle fibers stained with ferric ammonium citrate, scale bar 200 μm.Bottom: conventional micrograph showing the MRM coil. [1]Magnetic resonance microscopy (MRM, μMRI) is magnetic resonance imaging (MRI) at a microscopic level down to the scale of microns. [2]
It forms the outermost layer of the skin and the inner lining of the mouth, esophagus and vagina. [2] In the epidermis of skin in mammals, reptiles, and birds, the layer of keratin in the outer layer of the stratified squamous epithelial surface is named the stratum corneum. Stratum corneum is made up of squamous cells which are keratinized and ...
Scale bar is 20 μm. Fluorescence microscopy is a technique whereby certain molecules can be excited with one wavelength of light and will emit another longer wavelength of light. Because each fluorescent molecule has a unique spectrum of absorption and emission , the location of particular types of molecules can be determined.
Image at right shows influx of inflammatory cells including eosinophils and neutrophils in the dermis (solid arrow) and blister cavity (dashed arrows), and deposition of fibrin (asterisks). [15] However, the diagnosis of bullous pemphigoid consist of at least 2 positive results out of 3 criteria: [ 19 ]
Digital dermatoscopy (videodermatoscopy) is used for monitoring skin lesions suspicious of melanoma. Digital dermatoscopy images are stored and compared to images obtained during the patient's next visit. Suspicious changes in such a lesion are an indication for excision. Skin lesions, which appear unchanged over time are considered benign.
