Background: Necromys lasiurus belongs to a group that includes New World rats and mice. The few studies concerning N. lasiurus consider this species to be a good experimental model because they adapt easily and because maintenance in captivity is low-cost. Moreover, Cricetidae are epidemiologically important as vectors of various diseases. The aim of the present study was to describe the macroscopic and microscopic features of embryonic and fetal development in this species.
Methods: Totally, 8 embryos and 12 fetuses were used and allocated in 6 groups. Gestational age was determined by the crown-rump length (CR) and weight. After the gross descriptions, samples were processed for light microscopy.
Results: The groups differed both macroscopically (due the characteristics related to the cervical curve, elongation of li.. Read More»
