• Fibroblast behavior in the embryonic chick heart
    with M. Choy, S. Oltjen, D. Ratcliff, and P. Armstrong
    Intracardiac fibroblasts of Hamburger and Hamilton stage 36 chick heart reside in the epicardium and atrioventricular valves. The characteristics of the epicardial fibroblasts include segregation from the myocytes of the heart wall myocardium, voluminous extracellular matrix production, and some cell proliferation activity. The atrioventricular fibroblasts intermingle with myocytes at the mutual border between these tissues, produce smaller amounts of extracellular matrix, and show very active c…Read more
