Example Sentences:

(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.
(13) There mesodermal expansion proximal to an arrested edge could be compared with that proximal to a moving edge by measuring the amount of vascular elongation occurring in each.
(14) We also assessed the ability of ta2 limb bud mesoderm to respond to a polarizing signal.
(15) Invaginating mesodermal cells of the lateral and ventral parts also form pseudopodia, and are in contact with the blastocoelic wall.
(16) The aim of this study is to test the ability of the intrinsic wing musculature to develop in the absence of somitic mesoderm.
(17) Maintenance of GHox-8 expression by the anterior mesoderm appears to be independent of the presence of the apical ridge.
(18) Multiple hamartoma syndrome, also known as Cowden's disease, is a rare genodermatosis with multiple organ system involvement affecting tissues derived from ectodermal, endodermal, and mesodermal tissue layers.
(19) A unique pattern for a carbohydrate antigen is displayed by cells of the primitive streak; antigenicity is lost with de-epithelialisation and ingression, but is regained in a pericellular distribution on the mesoderm cells that emerge from the primitive streak.
(20) In the mutants twist and snail, which fail to differentiate the ventrally derived mesoderm, mitoses specific to the mesoderm are absent.

Definition:
(a.) Pertaining to, or of the nature of, a schizocoele.
