Manipulating the murine lacrimal gland

Area of Science:

• Ophthalmology
• Developmental Biology
• Anatomy

Background:

• The lacrimal gland (LG) produces aqueous tears vital for corneal health and vision.
• LG development involves epithelial branching morphogenesis, a process less understood in LG compared to other glands.
• Difficulties in LG dissection and culture hinder research.

Purpose of the Study:

• To describe standardized dissection techniques for embryonic and post-natal lacrimal glands (LG).
• To present methods for ex vivo culture of lacrimal gland tissue.
• To facilitate further research into lacrimal gland morphogenesis and function.

Main Methods:

• Detailed dissection protocols for harvesting mouse lacrimal glands (LG) at embryonic and post-natal stages.
• Established ex vivo culture methods for maintaining lacrimal gland tissue viability and structure.
• Photographic documentation of dissection procedures.

Main Results:

• Successfully demonstrated reproducible techniques for isolating intact lacrimal glands (LG).
• Established protocols for successful ex vivo culture of lacrimal gland explants.
• Provided a foundational resource for studying lacrimal gland development.

Conclusions:

• The described methods overcome previous technical barriers in lacrimal gland (LG) research.
• These techniques will enable detailed investigation into the mechanisms of lacrimal gland morphogenesis.
• This work supports the lacrimal gland as a viable model for studying epithelial development.
