Shell-less chick embryo culture the globe. Scientists designed drug delivery tests in mammalian embryos to treat degenerative diseases. It was implemented in India to scrutinize glucose-induced deformities in chick embryos. Shell-less chick embryo culture Shell-less chick embryo culture is the process of growing chick embryos "in vitro", without their protective egg shells, for scientific observation. Chick embryos and other avian embryos have been biological models to visualize the developmental stages of embryos for education and to instigate embryological manipulations. Using this technique, observations can be made, whether it is a induced-malformation caused due to effect of teratogens or the route of viruses inoculations such
