ABSTRACT THE mesogloea in ctenophores, as in certain coelenterates1,2, is essentially a third cell layer containing muscle cells, nerve cells and so-called “amoeboid” cells3,4. Our unpublished studies on _Beroe_ suggest that the “amoeboid” cells do indeed undergo a migratory phase during regeneration, but that there is no evidence of migration in the normal animal. Histological preparations show the cells with very long, thin processes connected together in the form of a net. We prefer to call them “mesenchymal” cells. We now have evidence from electron microscopy of specialized junctions between these mesenchymal cells and neighbouring muscle and nerve cells in _Beroe forskälii_ and _B. ovata_.

ABSTRACT THE mesogloea in ctenophores, as in certain coelenterates1,2, is essentially a third cell layer containing muscle cells, nerve cells and so-called “amoeboid” cells3,4. Our


unpublished studies on _Beroe_ suggest that the “amoeboid” cells do indeed undergo a migratory phase during regeneration, but that there is no evidence of migration in the normal animal.


Histological preparations show the cells with very long, thin processes connected together in the form of a net. We prefer to call them “mesenchymal” cells. We now have evidence from


electron microscopy of specialized junctions between these mesenchymal cells and neighbouring muscle and nerve cells in _Beroe forskälii_ and _B. ovata_. Access through your institution Buy
