The pigment cells of planarians react specifically to melatonin. This effect is also shown by serotonin, which is of chemically similar structure. A reaction is also evoked by histamine, but it differs from the reaction evoked by indole hormones. The experiments show that the cells of planarian regeneration blastema possess receptors for the hormones of higher animals.
