A detailed atlas of chick heart development in vivo

In this work we present the first reference catalogue of cardiac development in vivo with (1) 25 plates of high resolution colour images in different views from Hamburger-Hamilton (HH)-stage 12 (day 2, relatively straight heart tube, early myocardial contractions) through HH-stage 35 (day 9, four-chambered heart) in end-diastole and end-systole, including a plate with an overview of all these stages; (2) collection of 82 video recordings of beating hearts in different views corresponding to the stages shown in the plates.
