We describe an in vivo fluorescence imaging protocol to monitor muscle regeneration by GFP-labeled myoblasts after transplantation into skeletal muscles of both healthy and dystrophic mice. This protocol can be adapted to study muscle regeneration by transplantation of other types of cells and in other muscular conditions as well.

We describe a microsurgical approach for the generation of an arteriovenous (AV) loop as a model for analyzing vascularization in vivo in an isolated and well-characterized environment. This model is not only useful for the investigation of angiogenesis, but is also optimally suited for engineering axially vascularized and transplantable tissues.
FAQs
An intact animal preserves the coordinated relationships among immune cells, tissues, organs, and signaling pathways as infection or treatment unfolds. Those interactions can shape inflammation, protection, disease progression, and therapeutic effects in ways that isolated cells or tissues may not reproduce. This makes the approach useful when physiological context is central to the research question.
Researchers can introduce or observe infectious agents and then track responses across relevant biological levels, including immune cells, tissues, organs, and signaling pathways. Measurements over time connect the presence or progression of infection with inflammation, immune protection, or other treatment-related effects. This layered assessment helps link a biological mechanism to changes occurring throughout the organism.
Following responses over time can show how disease develops, how inflammation changes, and whether immune protection or a treatment effect persists during infection. A time-based view helps distinguish an early response from a later outcome. It also supports analysis of disease progression rather than limiting interpretation to a single physiological snapshot.
In Vivo Animal Studies can test whether an intervention changes infection-related outcomes within a physiological setting. Vaccine studies may examine immune protection, while antimicrobial or immunomodulatory strategies can be assessed through their effects on disease, inflammation, or host responses. Because the organism integrates immune and tissue-level consequences, results can inform later translational investigation.
A sound design should connect the infectious agent or intervention to the biological responses being measured and to the question about disease, immunity, or treatment. Investigators also need a defined observation period so progression and response can be interpreted over time. Careful study design is essential because conclusions depend on how these components are coordinated within the animal.
They can reveal changes in inflammation, immune protection, disease progression, treatment effects, and signaling pathways, rather than focusing only on whether an infectious agent is present. Examining immune cells together with tissues and organs adds physiological context to those findings. The resulting picture can connect cellular responses with broader consequences for the host.
They are particularly valuable when the research question concerns interactions that depend on an intact host, such as how infection progresses, how immune protection develops, or how an intervention affects multiple tissues. The approach complements studies of isolated cells or tissues by addressing organism-level responses. It is relevant to mechanism-focused work and evaluation of therapies or vaccines.
Animal welfare is a required part of responsible study design, not a separate consideration after the experiment. Researchers must incorporate welfare practices while addressing the scientific question through appropriate observations and measurements. This emphasis supports ethically conducted research and strengthens the interpretation of findings intended to evaluate infection, immune responses, treatments, vaccines, or later translational research.
