Hi all, I am Vicenta Salvador and I am interested in the development of excitability in the ascidian heart muscle. To start a project I first need to find the precursors to larval/adult heart muscle. The literature concerning the fates of the cells at the 8-cell ascidian embryo does not provide information as to which cells give rise to the heart. Would anyone know where/when to find them? Any suggestions will be appreciated Greetings from the Bamfield Marine Station! Vicenta
