What's the difference between embryo and subzonal?
Embryo
Definition:
(n.) The first rudiments of an organism, whether animal or plant
(n.) The young of an animal in the womb, or more specifically, before its parts are developed and it becomes a fetus (see Fetus).
(n.) The germ of the plant, which is inclosed in the seed and which is developed by germination.
(a.) Pertaining to an embryo; rudimentary; undeveloped; as, an embryo bud.
Example Sentences:

(6) In the stage 24 chick embryo, a paced increase in heart rate reduces stroke volume, presumably by rate-dependent decrease in passive filling.
(7) From the biochemical markers in follicular fluid, cyclic adenosine monophosphate has a distinct predictive value in regard to pregnancy in in vitro fertilization-embryo transfer cycles.
(8) Implantation of the mouse embryo involves the invasion of the secondary trophoblast giant cells of the ectoplacental cone (EPC) into the uterine decidua.
(9) They suggest that an endogenous retinoid could contribute to positional information in the early Xenopus embryo.

(13) Results obtained from cumulative labeling and pulse-labeling and chase experiments with cells from late gastrulae, yolk plug-stage embryos, and neurulae showed that the 30S RNA is an intermediate in rRNA processing and is derived from 40S pre-rRNA and processed to 28S rRNA.
(14) During that time they have repeatedly demonstrated the likely existence of signalling molecules or morphogens that control the pattern of development in the embryo.
(15) Ernst Reissner studied the formation of the inner ear initially using the embryos of fowls, then the embryos of mammals, mainly cows and pigs, and to a less extent the embryos of man.
(16) The objective of this study was to examine the effects of different culture media used for maturation of bovine oocytes on in vitro embryo development following in vitro fertilization.
(17) By 3 d in the chick embryo, the first neurons detected by antibodies to Ng-CAM are located in the ventral neural tube; these precursors of motor neurons emit well-stained fibers to the periphery.
(18) None of the factors tested was found to have a statistically significant effect on embryo yield.
(19) The embryo stages were assessed visually and some were investigated histologically.
(20) Ninety semen specimens were analysed for use in an IVF-embryo transfer (ET) programme.
Subzonal
Definition:
(a.) Situated under a zone, or zona; -- applied to a membrane between the zona radiata and the umbilical vesicle in the mammal embryo.
Example Sentences:
(1) In the subiculum, the plexiform layer was divided into a superficial, weakly stained subzone and a deep, better stained subzone.
(2) These findings suggest the feasibility and potential for further applications of a robotic microinsemination system and, in addition, that a higher fertility rate in the subzonal insemination of mouse ova can be achieved with the ionophore treatment of spermatozoa.
(3) by the formation of abundant pseudomycelium, absence of capsules, the assimilation properties, and its habitat: the north taiga subzone.
(4) The maximum response in the subzones decreased with increasing sequential distance from the dominant zone, so the response pattern across each side of the discharge field resembled a damped wave-form pattern.
(5) Although the tumour cells had the general appearance of a steroid-secreting cell their structure diverged from the cells of every subzone of the cortex.
(6) Young stock death rates, as well as general fertility rates varied in the ecological subzones with a marked effect in the zones labeled "Inland".
(7) Zone D contains three subzones mediolaterally in the rat.
(8) In the Mediterranean-Middle Asian subzone there are three types of focus: natural, semi-synanthropic, and synanthropic.
(9) Subzonal sperm insertion and partial zona dissection were applied in 250 in vitro fertilization cycles in couples (n = 200) with abnormal semen analyses; 61 clinical pregnancies were established (24% per egg retrieval).
(10) Methods were developed to facilitate the use of subzonal insemination to achieve fertilization in vitro.
(11) Using this robotic system, subzonal insemination with a single mouse spermatozoon was attempted in a total of 143 ova.
(12) The fact that not all zones and subzones are present in all members of the order means that this system permits identification of those ECM structures that have been gained or lost during Volvocalean evolution.
(13) Stratum radiatum and the superficial subzone of stratum oriens showed a weak staining intensity, contrasting to the relatively darkly stained pyramidal cell layer and the intensely stained deep subzone of stratum oriens.
(14) In a subgroup of 15 patients who failed IVF with insufficient numbers of motile sperm, fertilization was significantly higher after subzonal sperm insertion.
(15) Based on both their olivary and nuclear connections, 3 sagittal subzones can be distinguished within the D-zone of the rat.
(16) Two studies were performed: partial zona dissection and IVF was applied in 57 couples during the first period, and subzonal sperm insertion was also applied in a second group of 47 couples.
(17) An off-inhibitory zone consisted of near and distant subzones.
(18) The overall fertilization rate was 30.9% of the 433 oocytes that were intact after subzonal insemination.
(19) The existing experience on micromanipulation of gametes (zona-opening procedures, subzonal sperm insertion, and sperm microinjection into the ooplasm) has also demonstrated the clinical usefulness in assisted fertilization, suggesting a possible selective application of various micromanipulation techniques and their combinations in male infertility.
(20) The relative suppression in the subzones was as strong as in adult cells.
