Mobilization of shell calcium by the chick chorioallantoic membrane in vitro.
Two explants of shell were removed from each of several fertile eggs of domestic fowl at different times during incubation. The chorioallantoic membrane (CAM) was removed from one of the explants (SHELL ONLY) and was left in situ on the other (SHELL+CAM). Explants were cultured for 24, 48 or 96 h at 37 degrees C and 5% CO2 in air in individual Petri dishes containing Dulbecco's modified Eagle's...
متن کاملSupplemented eggshell restores calcium transport in chorioallantoic membrane of cultured shell-less chick embryos.
It was previously reported (Tuan, 1980a) that the development-specific expression of calcium transport and related functions in the chick embryonic chorioallantoic membrane (CAM) requires the continuous presence of the eggshell, the calcium source of the embryo. To further understand the mechanism of action of the eggshell on the CAM functions, this study reports the effects of eggshell supplem...
متن کاملCalcium-transport function of the chick embryonic chorioallantoic membrane. I. In vivo and in vitro characterization.
During chick embryonic development, the chorioallantoic membrane (CAM) is responsible for the mobilization of shell calcium into the embryonic circulation. The calcium-transport function of the CAM was studied here by measuring CAM calcium uptake in vivo and in vitro. The in vivo technique involved the use of an uptake chamber constructed on top of the CAM in situ. The in vitro methods included...
متن کاملStimulation of angiogenesis by adenosine on the chick chorioallantoic membrane.
The effect of adenosine on the vascular density of the chick chorioallantoic membrane was studied. Elvax polymer pellets containing 0.2-3.0 mg of adenosine were placed on the chorioallantoic membrane of 10-day embryos. Control pellets containing mannitol were placed at least 1 cm away. After 4 days the membrane was formalin-fixed and removed. A thin plastic coverslip, inscribed with concentric ...
متن کاملEvaluating the Effects of Enrofloxacin on Angiogenesis Using the Chick Embryo Chorioallantoic Membrane Model
Objective- Because little information was available in the literature about the angiogenic property of enrofloxacin, this investigation was undertaken to evaluate this aspect using an in vivomodel. Design- Experimental study. Animals- Twenty fertile chicken eggs (Ross 308) with the average egg-weight of 55 ± 0.4 g were rand...
