Observationoflivingandplasticembeddedchickembryos
The development of chick embryos has been studied since Aristotle. It is one of the most intensely studied organisms. One reason for this is that there are great similarities between avian and mammalian embryology. Another advantage is that the embryo is relatively accessible and can be operated on or treated with teratogens (substances that perturb development) while still in ovo(in the egg). Finally, fertilized chi......阅读全文
