What's the difference between embryonic and mesoderm?

Embryonic


Definition:

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

Example Sentences:

  • (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.

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.

Mesoderm


Definition:

  • (n.) The layer of the blastoderm, between the ectoderm and endoderm; mesoblast. See Illust. of Blastoderm and Ectoderm.
  • (n.) The middle body layer in some invertebrates.
  • (n.) The middle layer of tissue in some vegetable structures.

Example Sentences:

  • (1) Small pieces of anterior and posterior quail wing-bud mesoderm (HH stages 21-23) were placed in in vitro culture for up to 3 days.
  • (2) Here we report direct measurements of protein kinase C (PKC) activity in uninduced ectoderm, and in neuroectoderm shortly after induction by the involuting mesoderm, in Xenopus laevis embryos.
  • (3) Cloacal exstrophy, centered on the maldevelopment of the primitive streak mesoderm and cloacal membrane, results in bladder and intestinal exstrophy, omphalocele, gender confusion, and hindgut deformity.
  • (4) However, the pattern in the central nervous system (CNS) and mesoderm is further restricted; the major expression located in the labial neuromere of the CNS and the mesoderm of the first thoracic segment.
  • (5) The positive reaction for keratin and vimentin confirmed the presence of ectodermal and mesodermal elements respectively in the tumor.
  • (6) Little deficit in total mesodermal cell number was found, though the entire mesoderm adopted the histological character proper to only some 40% of that in the normal pattern i.e.
  • (7) LIF inhibits differentiation under several conditions which lead to endodermal and mesodermal cell lineages including skeletal and cardiac muscle.
  • (8) The histochemical study of the LDH in the Trout embryo during the early organogenesis shows a specific localization in notochord cells, in mesodermic cells of the terminal knob and in some prosencephalic neuroblasts.
  • (9) This suggests that a factor in the lateral plate mesoderm in addition to the pronephric duct is inhibiting further ventral migration.
  • (10) While such speculation on how these spatially separated anomalies develop is probably simplistic, the concept of a mesodermal "malformation" spectrum is helpful in reminding the clinician to look for other mesodermal defects when one mesodermally derived defect or sequence is detected.
  • (11) Cell biological evidence suggests that mesoderm formation and specification of axial positions occur simultaneously.
  • (12) The tissues of the endodermal and mesodermal origin were also present in small quantities.
