Micrograph of paper autofluorescing under ultraviolet illumination. The individual fibres in this sample are around 10 μm in diameter.. Autofluorescence is the natural emission of light by biological structures such as mitochondria and lysosomes when they have absorbed light, and is used to distinguish the light originating from artificially added fluorescent markers (fluorophores).
[78] [79] This feature confines far-UVC exposure to the superficial layers of tissue, such as the outer layer of dead skin (the stratum corneum) and the tear film and surface cells of the cornea. [ 22 ] [ 80 ] [ 81 ] [ 82 ] As these tissues do not contain replicating cells, damage to them poses less carcinogenic risk.
Tissue clearing refers to a group of chemical techniques used to turn tissues transparent. [ 1 ] [ 2 ] [ 3 ] By turning tissues transparent to certain wavelengths of light, it allows one to gain optical access to a tissue. [ 1 ]
Cell engineering is the purposeful process of adding, deleting, or modifying genetic sequences in living cells to achieve biological engineering goals such as altering cell production, changing cell growth and proliferation requirements, adding or removing cell functions, and many more.
Cuvettes for in-vitro electroporation. These are plastic with aluminium electrodes and a blue lid. They hold a maximum of 400 μl.. Electroporation, or electropermeabilization, is a technique in which an electrical field is applied to cells in order to increase the permeability of the cell membrane.
In the bottom half of the diagram, an HLA antibody that did not match the cell's HLA type was added, so there was no complement activation, and no cell lysis occurred. One of the first methods of tissue typing was through serological typing. In this technique, a donor's blood cells are HLA typed by mixing them with serum containing anti-HLA ...
Kidney and nerve tissue cells can form memories much like brain cells, one new study has found. Another recent study says that memories of obesity stored in fat tissue may be partly responsible ...
Micro-mass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. A commonly applied definition of tissue engineering, as stated by Langer [3] and Vacanti, [4] is "an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve [Biological tissue] function or a ...
