Immunoidentification of CRF-like material in the intermaxillary glands during Bufo arenarum development
The presence of corticotropin-releasing factor like material in the intermaxillary glands was studied by immunocytochemical techniques during the metamorphosis of Bufo arenarum. The intermaxillary glands appeared at stage XV (midprometamorphosis) with CRF-like material slightly immunoreactive. These...
