| 例句 | Each cell within the blastula is called a blastomere. Biology for AP Courses 2022-06-09T00:00:00Z Thus, Briggs and King’s results demonstrated that the nuclei in blastomeres are not irreversibly changed with differentiation. Cell identity reprogrammed 2019-10-13T04:00:00Z To determine the chromosome copy number, single or multiple blastomeres were biopsied from embryos at the cleavage stage and clumps of approximately five cells were microdissected from the trophectoderm of blastocysts. Genome editing reveals a role for OCT4 in human embryogenesis : Nature : Nature Research 2017-09-19T04:00:00Z DNA samples from 86 individual blastomeres representing different treatments and controls were sequenced using the MiSeq platform. Correction of a pathogenic gene mutation in human embryos : Nature : Nature Research 2017-08-01T04:00:00Z The fact that they are invariably of the same sex is a strong reason for believing that sex was already developed in the fertile ovum and consequently in the resulting blastomeres from that ovum. Being Well-Born An Introduction to Eugenics 2012-05-22T15:16:53.140Z Total cleavage occurs when divisions of the blastomeres are separate, whereas partial cleavage occurs when blastomeres stay partially connected. Biology for AP Courses 2022-06-09T00:00:00Z In the authors’ experiments, donor nuclei from cells at various developmental stages, from early blastomeres to cells from tadpoles just before hatching, were transferred into Xenopus egg cells. Cell identity reprogrammed 2019-10-13T04:00:00Z The hollow globe or sphere formed by the arrangement of the blastomeres on the periphery of an impregnated ovum. Webster's Unabridged Dictionary (2nd 100 Pages) 2012-03-24T02:00:19.387Z More importantly, all sister blastomeres in all but one embryo carried identical genotypes, indicating a marked reduction in mosaicism in M-phase-injected embryos. Correction of a pathogenic gene mutation in human embryos : Nature : Nature Research 2017-08-01T04:00:00Z It has been established experimentally in several kinds of animals that early cleavage blastomeres when isolated can each develop into a complete individual. Being Well-Born An Introduction to Eugenics 2012-05-22T15:16:53.140Z In 1888 Roux of Breslau by puncturing one blastomere of a frog's egg in the two-cell stage killed the punctured blastomere without affecting the other. Essays In Pastoral Medicine 2012-03-05T03:00:09.993Z But those who assume heterogeneous determinants do not thereby exclude what truth there may be in this view that what an early blastomere does is a function of its inter-relations. Herbert Spencer 2012-02-29T03:00:20.773Z Boveri found that in the case of the doubly fertilized egg the isolated “�” blastomeres develop very variously, a variability only to be accounted for by their varying chromosome equipment. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 8 "Cube" to "Daguerre, Louis" 2012-01-31T03:00:17.257Z DNA samples from 86 individual blastomeres representing different treatments and controls were sequenced using the MiSeq platform. Correction of a pathogenic gene mutation in human embryos : Nature : Nature Research 2017-08-01T04:00:00Z The N.I.H. now proposes to add to its list of approved cell lines those created from blastomeres, the cells generated after the fertilized egg’s first few divisions. Agency Proposes U.S.-Paid Research on Stem Cells 2010-02-20T02:11:00Z The punctured blastomere remained inactive, but the other developed into a complete half embryo. Essays In Pastoral Medicine 2012-03-05T03:00:09.993Z Segmentation of egg: the division of the originally single celled egg into a number of coherent cells or blastomeres; = cleavage. Explanation of Terms Used in Entomology In summary, too many parameters have been used to filter out off-targets and get to the conclusion that there were no ?detectable off-target mutations in selected blastomeres?. Correction of a pathogenic gene mutation in human embryos : Nature : Nature Research 2017-08-01T04:00:00Z The presence even of a single mutant blastomere within a mosaic embryo would make detection by PGD problematic; therefore, molecular mechanisms responsible for mosaicism were investigated. Correction of a pathogenic gene mutation in human embryos : Nature : Nature Research 2017-08-01T04:00:00Z The blastomeres in the human ovum may perhaps be injured in part by toxins from the mother, or they may be defective through disease in the ovum or the spermatozoon. Essays In Pastoral Medicine 2012-03-05T03:00:09.993Z In these cases of injured and isolated blastomeres we have, it seems to me, a plausible theory for the etiology of single terata.
