What's the difference between embryonic and histogenesis?

Embryonic


Definition:

  • (a.) Of or pertaining to an embryo; embryonal; rudimentary.

Example Sentences:

  • (7) Isoenzyme LDH4 was absent in the human pancreas in all the studied periods of embryonic development.
  • (8) The mRNA data of the developing gut correspond with previous protein data, which showed that the shorter Mr 210,000 polypeptide predominates during earlier developmental stages and the larger Mr 260,000 polypeptide appears later in the embryonic gut (Aufderheide, E., and P. Ekblom.
  • (9) Almost nothing is known about nature and timing of the embryonic cues which induce or initiate spicule formation by these cells.

  • (11) The junctional currents were already constant 1 ms after step changes in the junctional voltage; this was three orders of magnitude faster than the other known examples of voltage-controlled gap junctions between embryonic cells.
  • (12) Zona pellucida solubility, plasminogen activator production, and plasminogen conversion to plasmin increased as embryonic stage advanced; however, plasminogen activator production and plasmin conversion to plasmin were poorly correlated with zona pellucida solubility.

  • (15) p50B is able to form heteromeric kappa B-binding complexes with RelB, as well as with p65 and p50, the two subunits of NF-kappa B. Transient-transfection experiments in embryonal carcinoma cells demonstrate a functional cooperation between p50B and RelB or p65 in transactivation of a reporter plasmid dependent on a kappa B site.
  • (16) At the adult neuromuscular junction, acetylcholine (ACh) receptors are highly localized at the subsynaptic membrane, whereas, embryonic myotubes before innervation have receptors distributed over the entire surface.
  • (17) Embryonal carcinomas were found in 15 tumours, two being of pure type and the remaining 13 a part of mixed tumours.
  • (18) A large portion of the N-terminal globule of human collagen VI was prepared from the culture medium of stably transfected human embryonic kidney cell clones.
  • (19) The tissues were derived from the three germ layers and were prevalently mature; only a bit of them was represented by embryonic mesenchymal tissue.
  • (20) Phosphotyrosine-modified proteins were also abundant in and highly restricted to the process-rich layers of the embryonic optic tectum.

Histogenesis


Definition:

  • (n.) The formation and development of organic tissues; histogeny; -- the opposite of histolysis.
  • (n.) Germ history of cells, and of the tissues composed of cells.

Example Sentences:

  • (1) From this proliferating layer, precursor cells migrate outwards to reach the developing neostriatum in a sequential fashion according to two gradients of histogenesis.
  • (2) The aim was to clarify the nature of their constituent cells, specifically the giant ganglion-like cells and spindle cells, and to discuss the implications for histogenesis.
  • (3) Several stages in its histogenesis may be discerned: I. focal necroses of hepatic cells associated with their invasion with lister Listeria; 2. appearance of cellular elements around the foci of necroses with subsequent formation of granulemas consisting mainly of leucocytes and lymphoid cells; 3. development of necrobiotic changes in the central areas of granulemas with concomitance of exudative processes; 4. organization of necrotic foci with subsequent scarring.
  • (4) The histogenesis and relationship between the histopathological findings and clinical behaviour of uterine BL were also discussed.
  • (5) Considering the tumour's late occurrence the histological peculiarities of the place of origin as one of the factors of possible histogenesis is stressed.
  • (6) While the histogenesis of these tumors remain uncertain, it is necessary to recognize that these aggressive neoplasms may occur primarily in the skin.
  • (7) The characteristic anatomical distribution of BL is quite unlike that of most follicle centre-cell lymphomas and should be considered in the search for its histogenesis.
