title: Enhancement of cilia regeneration by hormone treatment of Tetrahymena.
abstract: Regeneration of cilia of deciliated Tetrahymena was modified by hormones added to the nutrient medium; it was enhanced by serotonin (an amino-acid type substance), insulin (a polypeptide-type hormone) and prednisolone (a steroid-type hormone). Diiodotyrosine, another amino-acid type hormone, did not influence regeneration. Prednisolone, a hormone morphogenetic in mammals appeared to be the most active in regenerating cilia.
