What's the difference between germinal and meroblast?
Germinal
Definition:
(a.) Pertaining or belonging to a germ; as, the germinal vesicle.
(n.) The seventh month of the French republican calendar [1792 -- 1806]. It began March 21 and ended April 19. See VendEmiaire.
Example Sentences:
(1) In contrast, in primordial follicles, FSH was restricted to the germ cell but was present in both the oocyte cytoplasm and germinal vesicle.
(2) T cells admixed in the germinal centers were overwhelmingly of the T-helper type.
(3) The lack of TBM prior to germinal center development and their absence in aged mice are inconsistent with the concept that TBM are required for the induction of the germinal center reaction.
(4) In contrast, Sca-2 did not appear to stain peripheral T lymphocytes, but recognized only a subset of B lymphocytes which could be localized by immunohistochemistry to germinal centers.
(5) The processes of germination and gruel preparation of germinated materials contributed to the digestibility of weaning foods prepared from cereals and legumes.
(6) The results presented here substantiate the hypothesis that in S. cerevisiae trehalose supplies energy during dormancy of the spores and not during the germination process.
(7) The response is dose dependent for LPA concentrations from 10(-8) to 10(-3) M. Incubation of oocytes in LPA does not induce germinal vesicle breakdown.
(8) Histologic examination showed multiple tissues derived from two or three germinal layers.
(9) The spore germination was synchronized by selection of the spores of the definite size and maintenance at a temperature of 0 degrees.
(10) GAD activity appeared in mutant spores after germination and increased to levels comparable to parent spores after 9 min of germination.
(11) A system for obtaining synchronous germination of mitospores is described.
(12) (2) Highly aneuploid and polyploid types were induced in diploid and haploid germinating conidia by chloral hydrate but not to any significant extent by gamma-rays.
(13) The observed signals from germinating seeds of Phaseolus aures and decaying leaves of Eucalyptus are presented to show that the signals have characteristic kinetics and intensity.
(14) The efficacy of combined cytostatic-surgical treatment was evaluated in a prospective study involving 70 patients with germinal tumors of the testis metastasizing into the lungs.
(15) Growth plate germinal cell division is directly related to the epiphyseal vascular respect.
(16) Germinal vesicle stage oocytes undergo perinuclear aggregation of acidic organelles during GVBD and these organelles subsequently disperse into the cell cortex as the first meiotic spindle migrates to the oocyte periphery.
(17) When oocytes were microinjected first with the mosxe antisense oligonucleotide, and subsequently with in vitro synthesized v-mos RNA, meiotic maturation was rescued as evidenced by germinal vesicle breakdown.
(18) Effects of alpha- or beta-D-glucose on the respiration of germinated spores (only germinated spores not including swollen spores and elongated spores) of Bacillus subtilis and B. megaterium were studied.
(19) Therefore, Leu 7+ (Leu 3+) germinal-center cells are distinct from "classic" T-helper cells of blood and lymphoid tissues.
(20) Either d- or l-leucine (10(-3)m) and unsaturated long-chain fatty acids such as oleic, linoleic, and arachidonic (10(-4)m) significantly stimulated macroconidia germination of Microsporum gypseum.
Meroblast
Definition:
(n.) An ovum, as that of a mammal, only partially composed of germinal matter, that is, consisting of both a germinal portion and an albuminous or nutritive one; -- opposed to holoblast.
Example Sentences:
(1) A hypothesis is put forward on pathways of changes of prospective importance of blastocoele in the vertebrate phylogenesis, in connection with their transition to meroblastic development.
(2) During meroblastic cleavage, and continuing in the early blastula, zebrafish blastomeres divide rapidly and synchronously.
(3) Cleavage (stages 1-10) is meroblastic and produces a typical teleost blastoderm.
(4) The problem on changes in assimilation of yolk by the vertebrate embryo at transition from holoblastic to meroblastic development is discussed from comparative point of view, as well as on nature of yolk entoderm in Amniota and Anamnia.
(5) The meroblastic egg of the teleost, Fundulus heteroclitus, was studied electrophysiologically from cleavage to mid-gastrula stages.
(6) Meroblast formation was effected by clefts originating from the parasite plasmalemma and by fusion of vacuoles with each other.
