What's the difference between endoderm and interlaminar?
Endoderm
Definition:
(n.) The inner layer of the skin or integument of an animal.
(n.) The innermost layer of the blastoderm and the structures derived from it; the hypoblast; the entoblast. See Illust. of Ectoderm.

(15) This finding suggests the identification of a cell population that is analogous to parietal endoderm in some eutherian animals.
(16) We recently showed that yolk sac is involved in the control of metabolism and action of vitamin D in the fetoplacental unit, since its endodermal cells contain a 24-hydroxylase for vitamin D metabolites and the 1,25-dihydroxyvitamin D receptor.
(17) These data thus demonstrate the production and presence of RBP mRNA and TTR mRNA, and the synthesis and secretion of RBP and TTR, by F9 cell embryoid bodies (specifically by visceral endoderm-like cells).
(18) We conclude that yolk-sac-derived teratomas are of endodermal origin because of the fact that the paternal X chromosome is inactivated in the yolk sac endoderm, whereas in the yolk sac mesoderm, as in the embryo, the inactivation is at random.
(19) A particularly interesting proteinase active at alkaline pH values is detected in the trophoblast-endoderm complex.
(20) It is therefore considered that, although there is good evidence that serum AAT is produced by endodermal sinus tumour elements, serum AAT is not a useful monitor of disease activity in these patients, especially when compared with serum AFP, the value of which is well recognized.
Interlaminar
Definition:
(a.) Between lammellae or laminae; as, interlamellar spaces.
Example Sentences:
(1) Whereas in flexion stress all methods showed a sufficient stability, the rotation tests proved, that in case of a dorsal instability of the lower cervical spine, posterior interlaminar wiring or anterior plate stabilization showed no reliable stabilization effect.
(2) The parvocellular layers were less densely labeled than other layers by the transport of 3H-proline, while concentrations of label were noted on the dorsal and ventral margins of the nucleus and in interlaminar regions between the internal parvocellular and magnocellular layers and between the two magnocellular layers.
(3) The recurrent projection from area 17 to the lateral geniculate nucleus arises from pyramidal neurons in layer VI, and terminates through all layers of the lateral geniculate nucleus, but most densely in the interlaminar zones.
(4) In 6 of 10 cases of dissecting aneurysm, the interlaminar fibers were apparently irregular in arrangement and shape, and decreased in number, especially in the outer media.
(5) Single unit extracellular recordings, cell size measurements, and cell packing density measurements were made in the medial interlaminar nucleus (MIN) of nine adult cats that had been monocularly deprived by lid suture prior to natural eye opening.
(6) However, after an injection limited to the prestriate cortex of Macaca, light autoradiographic labeling was seen in the interlaminar zones and the magnocellular and S laminae, demonstrating a prestriate-dLGN pathway.
(7) In the present study, we quantified the distribution of growth cones and synapses in 2 developing layers, as well as in the intervening interlaminar space of the dorsal lateral geniculate nucleus (dLGN) in tree shrews.
(8) The dendrites of interlaminar class II cells are organized along lines of projection and extend across as many as four layers.
(9) Because of their ease of use, rigid stabilization, good results, lack of complications, and compatibility with MR imaging, the Halifax interlaminar clamp with bone grafting provides an ideal method for posterior cervical stabilization.
(10) Existing methods using bone grafts, interlaminar wires, or acrylic eventually produce stability but require prolonged periods of immobility and have a high failure rate.
