Pituitary of non-pregnant and pregnant viscachas (Lagostomus maximus maximus): a comparative study by immunohistochemical and morphometric analysis
(Elsevier Gmbh, 2010-12)
The neuroendocrine hypothalamic-pituitary axis undergoes morphological and biochemical changes throughout gestation. In viscacha, pregnancy lasts approximately 154 days, and three stages can be described: early, mid- and ...
Variations in the adenohipophysis of the expression on proliferation cellular nuclear antigen, estrogen and androgen receptor in relation to gonadal steroids during pregnancy of viscachas (Lagostomus maximus maximus)
(Csiro Publishing, 2019-06-27)
Viscachas are native rodents of South America that present a long pregnancy of ~154 days. In this work, we analysed variations in the expression of proliferating cellular nuclear antigen, oestrogen and androgen receptors ...
