Research on the Human Conjunctival Fibroblasts is essential to the study of conjunctival fibrosis (e.g., pterygium, post-trabeculectomy scarring), ocular cicatricial pemphigoid, Stevens-Johnson syndrome complications, allergic conjunctivitis-related remodeling, and conjunctivochalasis. The eye is a complex sensory organ that allows an organism to perceive visual information. It is composed of the eyeball and its accessory structures. The eyeball is the main visual organ, responsible for image formation and phototransduction. The accessory parts include the eyelids, conjunctiva, lacrimal apparatus, extraocular muscles, and the connective tissue within the orbit, which together protect and enable movement of the eyeball. The Human Conjunctival Fibroblasts are to be used with Human Conjunctival Fibroblast Medium (Cat. No. ACM0118). This product is intended for laboratory in vitro use only. It is not intended for diagnostic, therapeutic, or clinical applications.
