Overview
This article describes a protocol for cannulating the mouse submandibular salivary gland via Wharton's duct. The use of trypan blue solution as a dye demonstrates the effectiveness of this technique for delivering infusions into the targeted gland, highlighting its potential for clinical applications in salivary gland regeneration.
Key Study Components
Area of Science
- Regenerative medicine
- Salivary gland function
- Cell therapy
Background
- Hypofunction of salivary glands is a common issue in conditions like Sjogren's syndrome.
- Therapeutic irradiation for head and neck cancers can lead to salivary gland dysfunction.
- Malfunctioning salivary glands can result in dental diseases.
- Innovative approaches are needed for the treatment of damaged salivary glands.
Purpose of Study
- To deliver progenitor or stem cells into the mouse submandibular salivary gland.
- To visualize cell infusion using trypan blue solution.
- To explore potential therapies for salivary gland regeneration.
