A 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 ...

Congenital Heart Disease and Other Malformations Produced by Influenza a Virus and Allantoic Fluid in the Chick Embryo.

II Although a number of explanations have been suggested, the etiology of congenital heart disease is still unknown. The teratogenie agents used in the experiments of other investigators" are seldom those encountered in clinical practice. Bpidemiological studies" have revealed the role of viral infections in the production of human cardiac malformations ; this led us to investigate the effect o...

Effect of retinoic acid on neural tube development in chick embryo

retinoic acid is one of the derivatives of vitamin A.it is used for treatment of dermatitis,but it has different teratogenic effects on developing organs depending on the different stages of embryonic life.neural  tube is made of two different parts:primary neural tube originated from embryo germinal layer and and secondary neural tube originated from tail bud.the persent study was designed to ...

Plaque formation of LaSota pathogenic strain of Newcastle disease virus adapted in chick embryo fibroblast cells

In order to adapt LaSota strain of Newcastle disease virus (NDV) on chick embryo fibroblast (CEF) cells, 0.1 ml from LaSota vaccine produced in Razi vaccine and serum research institute inoculated to the CEF cells and was passaged five times in the CEF grown in Eagle’s minimum essential medium (MEM). First to third passages were blind but in fourth passage cytopathic effect of virus was observe...
