Introducing Experimental Agents into the Mouse

JoVE 5161

Many investigations performed in mice (Mus musculus) require the administration of an experimental agent to the animal. For example, it may be of interest to test the efficacy of a specific therapy, to induce a pathologic condition, or to administer anesthesia or palliative care. In order to ensure safe and efficient delivery, it is important to consider a variety of factors prior to…

Murine In Utero Electroporation

JoVE 5208

In utero electroporation is an important technique for studying the molecular mechanisms that guide the proliferation, differentiation, migration, and maturation of cells during neural development. Electroporation enables the rapid and targeted delivery of material into cells by utilizing electrical pulses to create transient pores in cell membranes. Although…

Basic Mouse Care and Maintenance

JoVE 5158

Mice (Mus musculus) are small rodents that breed and sexually mature quickly, making them perfectly suited to generating large animal colonies for biological research. As compared to other mammalian species, mice are simple and inexpensive to maintain in the laboratory. Nevertheless, mouse colonies do have specific husbandry needs that are critical to preserving animal health and…
