Developmental Stages Selected for Cap Analysis of Gene Expression (CAGE) Study (IMAGE)
Caption
Representative images of chicken embryos used for RNA preparation and subsequent CAGE sequencing. Top panels show embryos in the first day of embryonic development (21 days in total), equivalent to the first five weeks of human gestation (first three weeks of human post-fertilization development). Bottom panels show embryos from the establishment of circulatory system to about a week before hatching, similar to the beginning of third trimester in human development.
