Rodents are mammals of the order Rodentia, characterized primarily by a single pair of ever-growing incisors in each of the upper and lower jaws, separated from the cheek teeth by a diastema and adapted for gnawing. This order encompasses extensive taxonomic diversity, including families such as Muridae, Cricetidae, Sciuridae, and Caviidae, occupying a wide range of terrestrial and arboreal habitats. Rodents exhibit high reproductive rates, diverse dietary strategies (from herbivory to omnivory), and complex social structures in some lineages. They play key ecological roles as primary consumers, seed predators and dispersers, and prey species, and serve as important model organisms in biomedical and evolutionary research.
In biomedical research using mouse models, preparing pseudopregnant recipient females is a standard step in embryo transfer protocols. Conventionally, this process requires technicians to select female mice showing clear ...
