Zebrafish is published bimonthly in print and online. Zebrafish, a model organism that plays an important role in biological research and the discovery and development of new drugs and cell-based therapies, can form embryonic stem cells (ESCs). For the first time, researchers report the ability to maintain zebrafish-derived ESCs for more than 2 years without the need to grow them on a feeder cell layer, in a study published in Zebrafish, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Zebrafish website.
