Induction of Myocardial Infarction in Adult Zebrafish Using Cryoinjury
Department of Biology, Unit of Zoology, University of Fribourg, Fribourg, Switzerland
Zebrafish represents a valuable model to study the mechanisms of heart regeneration in vertebrates. Here, we present a protocol for induction of a heart infarct in adult zebrafish using cryoinjury. This method results in massive cell death within 20% of the ventricular wall, similar to that observed in mammalian infarcts.

Modified Technique for Coronary Artery Ligation in Mice
Wallenberg Laboratory, Sahlgrenska Academy, University of Gothenburg
The surgical procedure used to induce experimental myocardial infarction in mice begins with left thoracotomy between the third and the fourth ribs in order to visualize the anterior surface of the heart and left lung. The left coronary artery is ligated, the chest is closed and the mouse is allowed to recover spontaneously.

Collection and Cryopreservation of Hamster Oocytes and Mouse Embryos
Unitat Biologia Cellular (Facultat de Biociències), Universitat Autonoma de Barcelona
In this video-article we present a step-by-step demonstration on how to collect and cryopreserve hamster oocytes with high post-thaw survival rates. The same procedure can also be applied to successfully freeze and thaw mouse embryos at different stages of preimplantation development.
