ChickEmbryostaging
In order to repeat a published experiment, or have someone else repeat yours, it is important to use the same materials. For developmental studies, that means knowing the precise point in development that the embryos have reached. The time of incubation gives only an approximation of the developmental age. For this reason, staging series based on morphologic criteria have been prepared.Chick embryos have been incubat......阅读全文
