Comparison of Culturing Methods of Primary Vaginal Fibroblasts

Area of Science:

• Gynecology
• Cell Biology
• Tissue Engineering

Background:

• Vaginal fibroblast function is altered in pelvic organ prolapse (POP).
• Understanding vaginal fibroblast behavior is crucial for elucidating POP pathophysiology.
• Standardized methods for primary vaginal fibroblast culture are needed.

Purpose of the Study:

• To compare the efficiency and outcomes of three distinct primary vaginal fibroblast culturing methods.
• To evaluate cell isolation efficiency, gene expression, and functional characteristics across methods.

Main Methods:

• An in vitro study involving primary vaginal fibroblasts isolated from patients undergoing POP surgery.
• Comparison of three culture methods: 3-hour digest, coverslip, and gelatin-coat.
• Analysis of cell confluency, fibroblast-associated gene expression (qPCR), morphology, viability, proliferation, and migration.

Main Results:

• The 3-hour digest method achieved cell confluency significantly faster (3-5 days) than coverslip and gelatin-coat methods (2-3 weeks).
• All three methods yielded comparable cell morphology, viability, proliferation, and migration.
• Similar expression levels of key fibroblast markers (vimentin, α-smooth muscle actin) and extracellular matrix genes (MMP1, MMP2, ACTA2, COL1A1, COL3A1, LOXL1) were observed across methods.

Conclusions:

• The 3-hour digest, coverslip, and gelatin-coat methods all reliably support primary vaginal fibroblast growth and function.
• The 3-hour digest method provides a more rapid approach to achieving confluent cultures.
• These findings support the selection of appropriate methods for vaginal fibroblast research in POP.
