Abstract

The invention provides a separation culture method of human fetal retinal pigment epithelial cells, relating to a method for separating fRPE (fetal retinal pigment epithelial) cells by utilizing a mechanical method and performing in-vitro culture. The separation culture method of the human fetal retinal pigment epithelial cells, provided by the invention, provides a new source for in-vitro culture, amplification of RPE (retinal pigment epithelial) cells and treatment of AMD (age-related macular degeneration) and other diseases with RPE injuries.

Description

technical field [0001] The invention relates to the field of biomedicine, and relates to the isolation and culture of human fetal retinal pigment epithelial cells (fRPE). Background technique [0002] RPE is a continuous monolayer of cells located outside the retina. It is named for its dice-like shape and abundant melanin in the cytoplasm. They play important functions in the maintenance and self-renewal of retinal cells, such as: phagocytosis and digestion of shed light OS of receptor cells; promote the regeneration of 11-cis-retinal, an important mediator in the visual cycle; regulate the immune response in the eye; participate in the formation of the retina-vascular barrier, etc. This abnormal physiological function of RPE cells is considered to be closely related to the occurrence of related eye diseases. For example, abnormal RPE cell barrier function can easily lead to Best vitelliform macular dystrophy (BVMD) and adult vitelliform macular dystrophy (BVMD) adult-onse...
