| Popis: | The development of the new pharynx in anterior body fragments of G. tigrina was followed for 7 days by immunocytochemical (ICC) study using antiserum to neuropeptide F (NPF) and muscle staining with phalloidin. ICC investigation revealed the presence of NPF in pharyngeal nervous system, peripheral nerve plexuses, in central nervous system of intact planarians. NPF-immunoreactive (IR) nerve fibres were found at the site of regeneration surrounding pharyngeal rudiment. Restoration of the pharynx function during regeneration was analysed by appearance of food response in anterior fragments. Stimulating effects of NPF and FMRF on the pharyngeal regeneration has been observed. The data indicates an important role of neuropeptides in morphogenetic processes. |
