1887 Jrnl. Morphol. 1 236 The change from a centripetal to a nucleopetal direction.

1956 Genetics 41 436 This type of melanocyte might be described as nucleopetal as contrasted with the commoner nucleofugal type.

1960 Q. Rev. Biol. 35 24/2 In ‘leaden’ and ‘dilute’ genotypes the melanocytes have fewer and finer dendritic processes and hence the pigment granules are largely clumped around the nucleus in the body of the cell. This type of pigment cell has been designated ‘nucleopetal’ as opposed to the more familiar melanocytes which are ‘nucleofugal’.
