Sex hormones change visceral pigmentation in Eupemphix nattereri (Anura): effects in testicular melanocytes and hepatic melanomacrophages
(Brill Academic Publishers, 2015-01-01)
Melanomacrophages and melanocytes are able to modify pigment intensity on the body surface as a response to temperature change, hibernation, hypoxia, infection, oxidative stress and exogenous use of hormones. This study ...
Pigmentation in Anuran Testes: Anatomical Pattern and Variation
(Wiley-Blackwell, 2009-02-01)
