| 单词 | mesodermal |
| 例句 | Muscle is contractile tissue and is derived from the mesodermal layer of embryonic germ cells. Fundamentals of Biology 2015-01-01T00:00:00Z The mesodermal tissues include support cells and secretory cells that secrete mucus and other materials to the surface. Concepts of Biology 2013-04-25T00:00:00Z They originate in the mesodermal germ layer and differentiate from mesenchyme and hematopoietic tissue in the bone marrow. Anatomy and Physiology 2013-06-19T00:00:00Z However, there were some slight differences between these cells and neighbours of direct mesodermal descent. A dual origin for blood vessels 2018-09-25T04:00:00Z However, such late mutations are rarely shared with the breast cancer sample from the same individual because the vast majority of them occurred after formation of the three germ layers, specifically in the mesodermal lineage. Somatic mutations reveal asymmetric cellular dynamics in the early human embryo : Nature : Nature Research 2017-03-21T04:00:00Z In protostomy, solid groups of cells split from the endoderm or inner germ layer to form a central mesodermal layer of cells. Fundamentals of Biology 2015-01-01T00:00:00Z The lack of many of these factors in indicates that ctenophore mesodermal cell types are specified differently than in bilaterians, suggesting that they perhaps evolved independently in these two lineages. [Research Article] The Genome of the Ctenophore Mnemiopsis leidyi and Its Implications for Cell Type Evolution 2013-12-12T19:26:12.817Z Paraxial mesodermal cells adjacent to the neural tube form blocks of cells called somites. Anatomy and Physiology 2013-06-19T00:00:00Z Whereas large sections of vascular smooth muscle are derived from the same developmental source, it seems that EMP-derived endothelial cells interlace with cells of direct mesodermal origin. A dual origin for blood vessels 2018-09-25T04:00:00Z S, serosa; A, amnion; E, ectoderm; N, rudiment of nerve-cord; M, mesodermal pouches. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 4 "Hero" to "Hindu Chronology" 2012-04-04T02:00:56.447Z The mesodermal tissues include mesenchymal cells that contain collagen and support secretory cells that secrete mucus and other materials at the surface. Fundamentals of Biology 2015-01-01T00:00:00Z We conducted extensive genomic inventories on signaling pathway components and genes known to be critical to neural and mesodermal cell types, among others. [Research Article] The Genome of the Ctenophore Mnemiopsis leidyi and Its Implications for Cell Type Evolution 2013-12-12T19:26:12.817Z Skeletal muscles, excluding those of the head and limbs, develop from mesodermal somites, whereas skeletal muscle in the head and limbs develop from general mesoderm. Anatomy and Physiology 2013-06-19T00:00:00Z In some cases they consist of masses of mesodermal cells, within which the excretory products appear to be stored up instead of being expelled from the body. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 7 "Crocoite" to "Cuba" 2012-01-22T03:00:24.397Z The paired oviducts and vasa deferentia are, as we have seen, mesodermal in origin. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 4 "Hero" to "Hindu Chronology" 2012-04-04T02:00:56.447Z This metamerism is thought to arise from identical teloblast cells in the embryonic stage, which give rise to identical mesodermal structures. Fundamentals of Biology 2015-01-01T00:00:00Z Up to the seventh month the pupil is closed by the membrana pupillaris, derived from the capsule of the lens which is part of the mesodermal ingrowth through the choroidal fissure already mentioned. Encyclopaedia Britannica, 11th Edition, Volume 10, Slice 1 "Evangelical Church Conference" to "Fairbairn, Sir William" 2011-07-16T02:00:16.387Z Whereas the ectoderm and endoderm form tightly connected epithelial sheets, the mesodermal cells are less organized and exist as a loosely connected cell community. Anatomy and Physiology 2013-06-19T00:00:00Z In some Annelids the central nervous system remains throughout life as part of the outer epidermis, but as a general rule it becomes separated from the epidermis and embedded in the mesodermal tissues. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 3 "Electrostatics" to "Engis" 2011-02-06T03:00:53.093Z Thus in many mammals the mesodermal part of the allantois often appears long before the endodermal part, though this is phylogenetically older. Form and Function A Contribution to the History of Animal Morphology Of all true mesodermal structures the hydra has actually none, but in the ectodermal and entodermal cells he has the potentiality of them all. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 |
