The distribution of the cytoplasmic organs varies considerably in different types of cells. While it frequently happens that both Golgi apparatus and mitochondria are grouped around the centrosome, yet in other cells the cytoplasmic organs are irregularly scattered throughout the cytoplasm. At the commencement of mitosis, the Golgi apparatus is usually divided into two parts, which are drawn to the opposite poles of the cell by the centrosomes, then the apparatus fragments, and in the daughter cells is reconstructed around their centrosomes. Other cases, however, have been described in which there is no appreciable attraction exerted by the centrosomes upon the cytoplasmic organs, at any stage of cell division (10). Da Fano (2), who has investigated the cytoplasmic organs in transplantable tumour cells, found that usually the Golgi apparatus is grouped around the centrosphere, either in the form of rodlets, or else as a fine or coarse network. In some growths, however, the distribution of the Golgi apparatus bore no relation to the centrosomes. The behaviour of the apparatus during mitosis was not specially investigated by Da Fano, but in those cases in which it presented the compacted form, he found that its division was associated with the division of the centrosomes at the prophase.
