Rat Submandibular Gland Decellularization Protocol and Scaffold Characterization

A research document detailing a rapid decellularization protocol for rat submandibular glands to create an extracellular matrix scaffold for tissue engineering. The protocol involves freeze-thaw pretreatment and detergent/enzyme incubations totaling approximately 5 hours, resulting in a scaffold with residual DNA below 50 ng/mg dry tissue. The document, authored by Jie Gao and last updated in April 2026, includes characterization data from histology, immunostaining, biochemical analysis, and proteomics, as well as recellularization and in vivo implantation results.

Use Cases

• Replicating a rapid decellularization protocol for salivary glands based on the described 5-hour detergent/enzyme method.
• Evaluating scaffold biocompatibility for cell repopulation based on described in vitro culture and in vivo implantation results.
• Analyzing preserved extracellular matrix components like collagens, laminin, and fibronectin based on the proteomic and immunostaining data mentioned.
• Studying stem cell behavior within a decellularized niche based on the described upregulation of matrix remodeling genes and epithelial marker expression.

Strengths

• The protocol achieved effective decellularization, reducing residual DNA to <50 ng/mg dry tissue.
• The resulting scaffold retained key structural proteins, including collagens I and IV, laminin, and fibronectin, as confirmed by multiple analyses.
• Recellularization experiments demonstrated cell viability and proliferation over 7 days in culture and successful in vivo implantation for 8 weeks.

Limitations

• The dataset is a single DOCX file; the underlying raw data tables, images, or proteomic datasets are not directly accessible in a structured format.
• Row count and column-level documentation are unknown, which may limit suitability assessment for computational analysis.
• The data is specific to rat submandibular glands; applicability to other species or tissues may require validation.
