Lobation

Lobation is a characteristic of the cell nucleus of certain granulocytes, which are types of white blood cells, where the nucleus is segmented into two or more connected lobes.^[1][2] Of the four types of granulocyte, only the mast cell is not lobated.

Lobation is also a characteristic of megakaryocytes in the bone marrow.^[2]
