1939, DA Webb, Henze (1913 a) was able to localize the vanadium chromogen in certain blood cells which he designated as morulae (Maulbeerformen). ... This type of cell, which, as will be shown later, is probably confined to the Ascidiidae and Perophoridae, is hereinafter referred to as a "vanadocyte", in order to distinguish it from other types of morulae which do not possess the properties just described.
2012, Poul Schever, Marine Natural Products V3: Chemical And Biological Perspectives, Such a solution would be expected to be an extremely complex mixture of molecules with possibility of artifact formation between vanadocyte vanadium and ligands originating from other cell types.
2013, F. Pietra, A Secret World: Natural Products of Marine Life, Vanadium can be stored in such an unusual form because of a reducing and complexing bright yellow pigment called tunichrome-B1, which is found in active blood cells called vanadocytes.
