[Human trabeculer cells in culture and cell identification]

Area of Science:

• Ocular biology
• Cell culture techniques
• Glaucoma research

Context:

• Human trabecular cells (HTCs) are vital for understanding intraocular pressure regulation.
• Primary open-angle glaucoma (POAG) pathogenesis requires reliable in vitro models.
• Previous methods for HTC culture and identification were suboptimal.

Purpose:

• To establish a reproducible method for culturing human trabecular cells (HTCs) in vitro.
• To identify key characteristics for distinguishing cultured HTCs from other ocular cells.
• To define essential criteria for the accurate identification of cultured HTCs.

Summary:

• Human trabecular cells (HTCs) were successfully cultured from donor eyeballs using optimized primary and subculture techniques.
• Cultured HTCs exhibited distinct morphological and growth characteristics compared to corneal and scleral cells.
• Immunohistochemical staining for fibronectin, laminin, and IV collagen in the extracellular matrix aided in HTC identification.

Impact:

• This study provides a foundational method for culturing and identifying HTCs, essential for glaucoma research.
• Accurate HTC identification is critical for investigating the mechanisms of primary open-angle glaucoma (POAG).
• The established methodology facilitates future research into POAG pathogenesis and potential therapeutic targets.
