In the preprimitive streak chick embryo, the search for a region capable of inducing the organizer, equivalent to the Nieuwkoop Center of the amphibian embryo, has focused on Kollers sickle, the hypoblast and the posterior marginal zone. However, no clear evidence for induction of an organizer without contribution from the inducing tissue has been provided for any of these structures. We have used DiI/DiO labeling to establish the fate of midline cells in and around Kollers sickle in the normal embryo. In the epiblast, the boundary between cells that contribute to the streak and those that do not lies at the posterior edge of Kollers sickle, except at stage X when it lies slightly more posteriorly in the epiblast. Hypoblast and endoblast (a second lower layer formed under the streak) have distinct origins in the lower layer, and goosecoid expression distinguishes between them. We then used anterior halves of chick prestreak embryos as recipients for grafts of quail posterior marginal zone; ...

1. The accumulation of [1-(14)C]glycine and the uptake, accumulation, incorporation (into protein, lipid, glycogen) and oxidation of l-[1-(14)C]leucine in 5-day-old chick embryo hearts were investigated in vitro, and the effects of insulin, puromycin and 4-methyl-2-oxopentanoic acid on these processes were studied. 2. With glycine, the ratio of concentration of the labelled amino acid in the cell water to that in medium markedly exceeded unity. Insulin significantly increased this ratio. Puromycin did not prevent the insulin effect. 3. With leucine, the concentration ratio of the labelled amino acid between intracellular and extracellular water approached unity in the absence of puromycin and was doubled by its presence. In neither case did insulin substantially alter this ratio. The addition of 4-methyl-2-oxopentanoic acid had no effect in the absence of insulin, but produced a significant increase of the concentration ratio in the presence of the hormone. 4. Leucine uptake was increased slightly by

We investigated the roles of sodium-calcium exchange, sarcoplasmic reticulum, and mitochondria in Cai homeostasis in cultured chick ventricular cells. Specifically, the influence of low sodium medium on contractile state, calcium fluxes, and cytosolic free [Ca] [( Ca]i) was examined. [Ca]i was measured using fura-2. Mean [Ca]i in control medium was 126 +/- 14 nM. Exposure of cells to sodium-free or sodium- and calcium-free medium (choline-substituted) resulted in contracture development, which returned toward the baseline level over 2-3 minutes. The Nao-free contracture was associated with a tenfold increase in [Ca]i (1,280 +/- 110 nM) followed by a gradual decrease to a level fourfold above control [Ca]i (460 +/- 58 nM). Nao- and Cao-free contracture was associated with a fivefold increase in [Ca]i (540 +/- 52 nM) followed by a rapid decrease to below 80 nM. Sodium-free medium failed to produce an increase in [Ca]i or contracture in cells preexposed to calcium-free medium, although caffeine, ...

MHM is a chicken Z chromosome-linked locus that is methylated and transcriptionally silent in male cells, but is hypomethylated and transcribed into a long non-coding RNA in female cells. MHM has been implicated in both localised dosage compensation and sex determination in the chicken embryo, but direct evidence is lacking. We investigated the potential role of MHM in chicken embryonic development, using expression analysis and retroviral-mediated mis-expression. At embryonic stages, MHM is only expressed in females. Northern blotting showed that both sense and antisense strands of the MHM locus are transcribed, with the sense strand being more abundant. Whole mount in situ hybridization confirmed that the sense RNA is present in developing female embryos, notably in gonads, limbs, heart, branchial arch and brain. Within these cells, the MHM RNA is localized to the nucleus. The antisense transcript is lowly expressed and has a cytoplasmic localization in cells. Mis-expression of MHM sense and antisense

We have studied the lineage history of the progenitors of the somite mesoderm and of the neural tube in the chick embryo by injecting single cells with the fluorescent tracer, rhodamine-lysine-dextran. We find that, although single cells within the segmental plate give rise to discrete clones in the somites to which they contribute, neither the somites nor their component parts (sclerotome, dermatome, myotome or their rostral and caudal halves) are `compartments in the sense defined in insects. Cells in the rostral two thirds or so of the segmental plate contribute only to somite tissue and divide about every 10 h, while those in the caudal portions of this structure contribute both to the somites and to intermediate and lateral plate mesoderm derivatives. In the neural tube, the descendants of individual prospective ventral horn cells remain together within the horn, with a cycle time of 10 h.. We have also investigated the role of the cell division cycle in the formation and subsequent ...

Annulate lamellae have been observed in the myocardium of 18-day-old chick embryos maintained at the normal temperature of 100°F and at 90°F during the last week of incubation. An increased number of annulate lamellae was observed in heart muscle of embryos incubated at 90°F. This is probably caused by a persistent production of these organelles, since annulate lamellae are present in greater frequency than in 11-day-old embryos incubated at 100°F. In the hypertrophic hearts of 18-day-old embryos incubated at 90°F, the annulate lamellae were associated with a net increase of protein content and an elevated concentration of myocardial glycogen. It is suggested that the increased number of annulate lamellae is a sequela of reduced environmental temperature during incubation. ...

In 1951 Viktor Hamburger and Howard Hamilton created an embryonic staging series from a combination of photographs and drawings from other researchers. The Hamburger-Hamilton stages are a sequence of images depicting 46 chronological stages in chick development. The images begin with a fertilized egg and end with a fully developed chick. The Hamburger-Hamilton staging series was produced in order to replace a previous chick staging series created in 1900. The earlier attempt lacked specific details and staged the chick embryo by using only morphological characteristics.. Format: Articles Subject: Processes ...

Acetylcholine, acetyl-β-methylcholine and carbamylcholine inhibited sinoatrial pacemaker activity in atria isolated from chick embryos on the 6th, 12th and 18th incubation days. Cardioinhibition persisted throughout the 5-minute exposure to cholinergic agonists in sinoatrial preparations from the 12th and l8th incubation days whereas automaticity recovered completely within 1 to 2 minutes in preparations from the 6th incubation day. Neither hydrolysis by acetylcholinesterase nor release of catecholamines from cardiac stores accounted adequately for the brevity of pacemaker inhibition by choline esters on the 6th incubation day. Evidence suggested that desensitization, most prominently observed with carbamylcholine, restricted the duration of cholinergic inhibition of the pacemaker on the 6th incubation day. Although automaticity recovered completely within 2 minutes after initial application of acetylcholine and carbamylcholine, pacemaker cells were not inhibited by a second application until ...

AU - Chuai, Manli. AU - Lee, Kenneth Ka Ho. AU - Kurihara, Hiroshi. AU - Yang, Xuesong. PY - 2014/9. Y1 - 2014/9. N2 - Background The developing embryo is very sensitive to oxidative stress and excess reactive oxygen species (ROS) generation is often associated with cardiovascular malformation. However, little is known about the adverse effects of ROS during heart morphogenesis, especially during the formation of the atria and ventricles. Methods and Results We have treated early chick embryos with 2,2-azobis (2-amidinopropane) dihydrochloride (AAPH) to generate free radicals in the developing heart. We established that excess ROS induced by AAPH caused cardiomegaly to develop in 4-, 14- and 17-day-old embryos. The cardiomyocytes of these AAPH-treated hearts were hypertrophic, in both the compact and ...

TY - JOUR. T1 - Molecular analysis of regulative events in the developing chick limb. AU - Mahony, Chris. AU - Vargesson, Neil. PY - 2013/7/1. Y1 - 2013/7/1. N2 - The developing chick limb has the remarkable ability to regulate for the loss of large amounts of mesenchyme and maintain a normal limb pattern in early (Hamburger and Hamilton Stage 19; E3) limbs. How the limb can regulate for tissue loss and why this ability is lost as development proceeds (after Hamburger and Hamilton Stage 21; E3.5) is unclear. We have investigated the origins of cells involved in regulative processes and, for the first time, the molecular changes occurring, and find striking differences between developmental time points just 0.5 days apart. We demonstrate that subtle changes in cell dispersal and cell proliferation occur in HH St21 limbs but not in HH St19 limbs and also demonstrate that there is no net replacement of removed tissue at either HH St21 or St19. We further show that changes in the ...

The tracheal organ cultures (TOC) were prepared with tracheas from 19-day-old chicken embryos, The 1-2 mm thick rings were hand chopped and transfered to tubes with different medium cultures with five repetions of each for comparative evaluation and kept under continuous rotation using a roller and sored at 37° C. Medium RPMI 1640 added with HyQCCM proved superior in maintaining ciliary activity as compared to non-supplemented 199, or RPMI 1640 media. The rings with good (50%) and excellent (100%) ciliary activity, 24 or 48 hours aiier the preparation, were evaluated as regards sensibility to titration of a IBG and to the test of serum neutralisation. The use of TOC was evaluated for the titration of IBV strains M41, A5968 and H-120. The vaccine strains H-120 was carried out simultaneously and compared to the titration in embryonated hens eggs (EE) SPF. Results of titration of IBV in TOC, as compared to EE, were reproducible and represent na excellent alternative to titrating IBV field strains, ...

Paranemin was initially found to copurify with the intermediate filament (IF) proteins vimentin and desmin from embryonic chick skeletal muscle and was described as an IF-associated protein (IFAP). We have purified paranemin from embryonic chick skeletal muscle, prepared antibodies, and demonstrated that they label at the Z-lines of both adult avian and porcine cardiac and skeletal muscle myofibrils. We determined the cDNA sequence of paranemin by immunoscreening a λgt22A cDNA library from embryonic chick skeletal muscle. Northern blot analysis revealed a single transcript of 5.3 kilobases, which is much smaller than predicted from the size of paranemin (280 kDa) by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The derived amino acid sequence of paranemin (1,606 residues; 178,161 kDa) contains the conserved IF rod domain (308 amino acids), which has highest homology to the rod domains of nestin and tanabin. Thus, paranemin is an IF protein rather than an IFAP. Sequence analysis ...

Developmental changes in regulation of embryonic chick heart gap junctions.: Embryonic chick myocyte pairs were isolated from ventricular tissue of 4-day, 14-da

Duodena from 20-day-old chick embryos can be maintained in large scale organ culture on specially designed stainless-steel grids in contact with serum-free medium for 48 h with excellent preservation of mucosal structure at both the light and electron microscope levels. Although mitotic rate was subnormal, several other factors attest to the essential viability of the cultured intestine: L-leucine incorporation into protein, as well as the synthesis of a specific vitamin D3-induced calcium-binding protein (CaBP), increased over a 48-h culture period, and the electropotential gradient across the intestine was maintained throughout the culture period as was a concentration gradient for calcium. The tissue responded to vitamin D3 in the medium by synthesizing the calcium-binding protein within 6 h and by exhibiting enhanced 45Ca uptake within 12-24 h. Concentrations of vitamin D3, or its 25-hydroxylated derivative, higher than necessary for CaBP induction, also increased the activity of alkaline ...

The differentiation of chick embryonic skeletal myoblasts results in the formation of myotubes which are the precursors of muscle fibres. The fusion of mononucleated myoblasts represents an apparent switching point in differentiation since it results in both the formation of multinucleated myotubes and the stimulation of muscle specific protein synthesis. The aim of this project has been to examine the biochemical events involved in this process of terminal differentiation by using primary cultures of chick embryonic myoblasts as a model system.. ...

TY - JOUR. T1 - WNT signals control FGF-dependent limb initiation and AER induction in the chick embryo. AU - Kawakami, Yasuhiko. AU - Capdevila, Javier. AU - Büscher, Dirk. AU - Itoh, Tohru. AU - Esteban, Concepción Rodríguez. AU - Izpisua Belmonte, Juan Carlos. PY - 2001/3/23. Y1 - 2001/3/23. N2 - A regulatory loop between the fibroblast growth factors FGF-8 and FGF-10 plays a key role in limb initiation and AER induction in vertebrate embryos. Here, we show that three WNT factors signaling through β-catenin act as key regulators of the FGF-8/FGF-10 loop. The Wnt-2b gene is expressed in the intermediate mesoderm and the lateral plate mesoderm in the presumptive chick forelimb region. Cells expressing Wnt-2b are able to induce Fgf-10 and generate an extra limb when implanted into the flank. In the presumptive hindlimb region, another Wnt gene, Wnt-8c, controls Fgf-10 expression, and is also capable of inducing ectopic limb formation in the flank. Finally, we also show that the induction of ...

Pretreatment of mouse L cells with mouse interferon (IFN) inhibits the penetration of vesicular stomatitis virus without affecting viral adsorption. The inhibition of virus uptake by IFN is dose dependent and, at the highest dose tested (1,000 units/ml), reaches 65%; 24 hr of treatment with IFN are required for maximal effect. A similar inhibition of uptake of virus occurs in human diploid fibroblasts and primary chicken embryo fibroblasts treated with homologous IFN. No significant inhibition occurs when cells are treated with heterologous IFN. These results document a previously unrecognized antiviral effect of IFN--namely, inhibition at the level of viral uptake.. ...

Chimaeric alleles were constructed to assay the biological functions of an N-terminal deletion and C-terminal mutations which were found in a naturally occurring mutant of feline vMyc, T17. The mutant alleles were assayed for their ability to transform chick embryo fibroblasts in vitro by a number of criteria, namely the ability to induce morphological transformation, an accelerated growth rate and growth in soft agar. Feline cMyc could transform the avian cells, whilst T17 vMyc could not, and the N-terminal deletion was responsible for conferring the primary transformation defect on the mutant protein. The C-terminal mutations which consist of a point mutation adjacent to the nuclear localisation signal and a point mutation/amino acid insertion within the basic region (BR) could, however, dissociate the Myc-induced parameters of transformation. This effect was a specific function of the BR mutation alone, and the mutation could be transferred into avian cMyc with comparable biological ...

In a series of tissue cultures of fragments taken from different parts of young chick embryos, at various stages, it was found that differentiation frequently occurred, the characteristic cells of highly specialised tissues appearing in cultures in which they could not possibly have been present at explantation. The most striking differentiations were the development of red blood corpuscles, capillary vessels, nerve cells with axons and of rhythmically contracting cardiac muscle. This paper describes a simple method by which may be obtained regularly and quickly the development of very large numbers of red cells, and an account is given of the histology of the cultures. It is intended to be introductory to a physiological study, now in progress, of the conditions of hæmatopoiesis Literature. Erythropoiesis in vitro has been reported by several authors, but it has not been thoroughly investigated and, with the exceptions of the works of Slonimski (1930, a, 1931) and Shipley (1915-16), the ...

Simultaneous left and right atrial surface electrograms were obtained from the right and left atria of 30 chick embryos. These were divided into 3 equal groups that were studied at 15 to 16, 10 to 11, and 5 to 7 days of incubation. The embryos were removed from the shell with their circulation intact and temperature maintained constant. In an early stage of development (5 to 6 days), the left atrium and its appendage were larger than the right, and left preceded right atrial depolarization. At and after 7 days of incubation, the right atrium and its appendage were larger than the left, and right preceded left atrial depolarization. The intervals for interatrial conduction and for atrio-ventricular conduction were about the same at all stages of development. Since the length and width of the heart at 15 to 16 days of incubation were about 3 times those of a heart at 5 to 7 days of incubation, it is proposed that the higher the stage of development of the chick embryo the greater must be the ...

Romans 5:3-4: Not only so, but we also glory in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope.. The first step in chick hatching is called pipping. This is when the chick first breaks through a small hole in the outside of the shell. The chick is still considered an embryo at this stage, because it is not fully developed or ready to hatch. The following 8 - 18 hours allow the chicks body to make some final developments for the outside world. The chicks body will absorb the remains of the yolk sack and its lungs will adapt to the change in air pressure.[i] To assist the chick in exiting the egg at this stage would be dangerous, and usually fatal. While it may be difficult to just watch the chick struggle, when we understand that this stage is vital to the chicks development, it is easier to sit back and wait.. A good coach will know when to allow their athletes to struggle on their own. While it is tempting to give advice ...

Newly hatched chicks are covered in dark downy feathers above with white bellies. Unlike adult loons, a young loon chick is able to walk upright on land. Although they can swim immediately after hatching, chicks spend a lot of time riding on their parents backs during the first several days of their lives. This helps to regulate their body temperature and protects them from underwater predators. Chicks are entirely dependent on their parents for food, and one adult typically remains on the waters surface with the chicks while the other catches fish and feeds them.. ...

A method for the determination of red cell mass, which employs the use of radioisotopically-labeled erythrocytes, in the embryonated hen egg is described and results of total blood volume, plasma volume, red cell mass and red cell concentration determinations during the period from 9 to 18 days of incubation presented. Considerations of the values obtained in terms of absolute quantities and relative to embryonic mass are discussed. It is suggested that expansion of the red cell mass and somatic growth are portions of a common process and may be subject to a complex of similar regulatory factors in the normal chick embryo.. ...

BACKGROUND: Chicken embryos are widely used as a model for studies of obesity; however, no detailed information is available about the dynamic changes of proteins during the regulation of adipose biology and metabolism. Thus, the present study used an isobaric tags for relative and absolute quantitation (iTRAQ)-based proteomic approach to identify the changes in protein abundance at different stages of chicken embryonic development. RESULTS: In this study, the abundances of 293 hepatic proteins in 19-day old of chicken embryos compared with 14-day old and 160 hepatic proteins at hatching compared with 19-day old embryos were significantly changed ...

Since Ms. Cormier was willing to house the chicks on her farm after the class finished with them, I decided that bringing back, and even expanding, this work with live chicks seemed like a really good fit for my vision for the course, said Bailey.. Unfortunately, there have been incidents of chicks passing away. After a power outage in Gelb while the eggs were still incubating, the humidity dropped very low in the incubator. The chicks were already partially hatched during this time, causing the exposed membrane to dry up. According to students interviewed by The Phillipian, two chicks did not hatch as a result of the outage.. The first 36 hours after hatching are a critical time for the chicks - after this period, the birds switch from innate imprinting to associative learning and will not be able to imprint on their mother. According to students, another factor that facilitates the imprinting process is being rough and showing tough love to the chicks.. Macey Mannion 19 said, If we spent ...

Hello, everybody! Does anyone have any experience with RNase Protection Assay? I have been doing it for a few months now, using a non-radioactive method for detection (biotin) and I have problems with transferring from the PAGE to a nylon membrane (low efficiency of transfer). My other problem is that after I stain the urea/PAGE with EtBr I see the same band pattern with my control probe (beta-actin) and with my probe (in this case for titin). Its absolutely the same picture-with actin, with titin and with both probes. What I am looking for is differential expression of titin at different stages of primary chick embryo muscle culture and if there is no way of comparing titins expression with that of actin (housekeeping gene), I am in a bad shape. I would greatly appreciate any help! Thanks a lot in advance!

The most commonly used commercial method for sexing chicks as young as 1 day old is called vent sexing. We strongly discourage any amateur chicken keeper from trying this as it can cause severe injuries to the chick if done improperly. The people who do this commercially are professionally trained in doing so which means you are unlikely to be able to sex your chicks even if you do the method correctly. In a nutshell the method involves inspecting the inside of the chicks vent for a very small lump (to signify male) or no lump (to signify female). As said before, please do not try this without proper training as you are likely to injure or even kill your chicks and you still probably wont know if you have boys or girls.. ...

in which she provides a sarcastic quiz with a series of multiple-choice questions as to the books author, cover, main character and themes in order to highlight chick lit as formulaic (Ferriss and Young, 2006: 1).. On the one hand, it is perhaps unsurprising that chick lit has garnered a fair degree of criticism. Along with external clearly gendered cover art and the internal preoccupation with the search for a man, the very term chick lit, as Imelda Whelehan (2005: 171) points out, is simultaneously interesting and provocative, as the term brings into play both negative and positive connotations, and raises issues of gender and genre (Gormley, forthcoming). As Jane Mills (1989: 47) notes, the term chick, when applied to humans, first entered the English language circa 1400 to mean a child or young girl. In the 1500s, chick became, a term of endearment applied to a female sweetheart; yet by the early 1900s the term had degenerated to denote, a young promiscuous woman (ibid.). In the ...

One was named Spotty because he had black spots on him. I loved listening to the sound of the chicks chirping. They are so cute!
