I-19: Surrogate Egg Shell Culture for The Analysis of Avian Stem Cell Fate
Background: The chick embryo is a classical model to study embryonic development. However, most researchers have not studied the effect of embryonic manipulation on chick hatchability. To determine the effect of egg orientation and type of sealing film on the hatchability of cultured embryos, and to determine the fate of adulte stem cells injected into the blastoderm. Materials and Methods: Win...
متن کاملThe Role of Caspase 9 during Programmed Cell Death in Ciliary Ganglia of Chick Embryos
During programmed cell death (PCD) apoptosis is controlled by many factors such as proteases. With no specific protease (s) known during PCD in the developing nervous system so far, we sought to determine if any specific protease (s) is involved in this process and therefore used different protease inhibitors during PCD (from embryonic day 6 to 10) in chick embryos. Among the inhibitors commerc...
متن کاملInvestigation on the teratogenic and embryotoxic effects of nanozeolite on chick embryos model
Objective(s): In veterinary medicine, zeolites are used as toxin binder in animal feed, ammonia purification of aquatic pools, animal smell and moisture control. This study investigated on the risk assessment of nano zeolite on development of embryonic chicken models, anomalies, tetratogenic and embryotoxic effects. Methods: Eggs (120 = n) were accidentally di...
متن کاملA Chick Embryo in-Vitro Model of Knee Morphogenesis
Background: In this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. Methods: The developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of ...
متن کاملInvestigating of the methods used to find external agents in vaccines and biological products
multiple technological levels the necessity of developing vaccine quality control systems is one of the requirements of our country Coordinated tests of the absence of externous agents in biological substances are considered as a major international concern for veterinary vaccines. Exogenous agents such as Newcastle disease virus, avian leukosis virus, infectious laryngotracheitis virus (ILTV)...
