The goal of this protocol is to establish an orofacial muscle fibrosis model. Comparison of the histology between mice masseter and tibialis anterior muscle after freezing injury confirmed masseter muscle fibrosis. This model will facilitate further investigation into the mechanism underlying orofacial muscle fibrosis.

Skeletal muscle regeneration is driven by tissue resident muscle stem cells, which are impaired in many muscle diseases such as muscular dystrophy, and this results in the inability of muscle to regenerate. Here, we describe a protocol that allows the examination of muscle regeneration in zebrafish models of muscle disease.
FAQs
The pouch places the test material or graft in direct proximity to living muscle, where host cells and blood vessels can interact with it. This creates a controlled tissue environment for observing whether the construct becomes integrated, develops vascularization, provokes inflammation, or undergoes remodeling. The model therefore connects material behavior with biological performance in vivo.
The surrounding muscle supplies both mechanical support and a biological interface for the implanted construct. That combination lets investigators study how the construct behaves while exposed to host cells and blood vessels, rather than evaluating material properties in isolation. In bioengineering, this helps link scaffold or graft design to integration, vascularization, inflammation, and remodeling outcomes.
Integration, vascularization, inflammation, and tissue remodeling provide distinct but related readouts. Integration indicates how the construct is accommodated within host tissue, while vascularization addresses access to blood vessels. Inflammation reveals a host response, and remodeling captures changes over time. Evaluating these outcomes together gives a broader assessment of biological performance than any single readout.
The workflow begins with surgical creation of a muscle pouch, followed by placement of a biomaterial, cell-laden construct, or tissue graft inside it. Researchers then assess the implanted material or tissue in the living environment, focusing on integration, vascularization, inflammation, and remodeling. This sequence provides a structured way to compare biological performance among engineered candidates.
The model can be applied to scaffolds, engineered muscle, drug-delivery systems, and regenerative therapies. Its value depends on the question being tested: investigators may examine how a material integrates, how a construct becomes vascularized, how a delivery system behaves in tissue, or whether a therapy supports remodeling. These applications bridge design with preclinical evaluation.
For bioengineering, the Muscle Pouch Model helps identify design factors associated with functional tissue repair before more advanced preclinical studies. Researchers can connect material design or construct development with observed host responses in living muscle. This feedback supports refinement of engineered constructs and therapies and may improve their translation toward regenerative applications.
