  2. Angiogenesis - Wikipedia

    en.wikipedia.org/wiki/Angiogenesis

    Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels, [1] [2] [3] formed in the earlier stage of vasculogenesis. Angiogenesis continues the growth of the vasculature mainly by processes of sprouting and splitting, but processes such as coalescent angiogenesis , [ 4 ] vessel elongation and ...

  3. Vasculogenesis - Wikipedia

    en.wikipedia.org/wiki/Vasculogenesis

    Vasculogenesis, in contrast, is when endothelial precursor cells (angioblasts) migrate and differentiate in response to local cues (such as growth factors and extracellular matrices) to form new blood vessels. These vascular trees are then pruned and extended through angiogenesis.

  4. History of manufactured fuel gases - Wikipedia

    en.wikipedia.org/wiki/History_of_manufactured...

    The first attempts to manufacture fuel gas in a commercial way were made in the period 1795–1805 in France by Philippe LeBon, and in England by William Murdoch. Although precursors can be found, it was these two engineers who elaborated the technology with commercial applications in mind.

  5. Fuel gas - Wikipedia

    en.wikipedia.org/wiki/Fuel_gas

    Fuel gas is contrasted with liquid fuels and solid fuels, although some fuel gases are liquefied for storage or transport (for example, autogas and liquified petroleum gas). While their gaseous nature has advantages, avoiding the difficulty of transporting solid fuel and the dangers of spillage inherent in liquid fuels, it also has limitations.

  6. Gaseous signaling molecules - Wikipedia

    en.wikipedia.org/wiki/Gaseous_signaling_molecules

    Gaseous signaling molecules are gaseous molecules that are either synthesized internally (endogenously) in the organism, tissue or cell or are received by the organism, tissue or cell from outside (say, from the atmosphere or hydrosphere, as in the case of oxygen) and that are used to transmit chemical signals which induce certain physiological or biochemical changes in the organism, tissue or ...

  7. Peripheral chemoreceptor - Wikipedia

    en.wikipedia.org/wiki/Peripheral_chemoreceptor

    A high concentration of central chemoreceptors is found in the ventral medulla, the brainstem area that receives input from peripheral chemoreceptors. [12] Taken together, these blood oxygen monitors contribute nerve signals to the vasomotor center of the medulla which can modulate several processes, including breathing, airway resistance ...

  8. Proteases in angiogenesis - Wikipedia

    en.wikipedia.org/wiki/Proteases_in_angiogenesis

    The formation of capillaries from pre-existing blood vessels requires the remodeling of both the peicapillary membrane of the parent venule, as well as the local and distal ECM. At the onset of angiogenesis endothelial cells (EC) must remodel three different barriers in order to migrate and invade the target tissue.

  9. Precursor cell - Wikipedia

    en.wikipedia.org/wiki/Precursor_cell

    Due to their contribution to the development of various organs and cancers, precursor and progenitor cells have many potential uses in medicine. There is ongoing research on using these cells to build heart valves, blood vessels, and other tissues by using blood and muscle precursor cells. [2]
