Problems solved by technology

[0003] At present, there are very few human retinal Muller cells available at home and abroad, and there are few studies on normal retinal Muller cell culture methods in vitro, and most of the methods are unstable. In addition, the eyeball tissue is not easy to obtain, which seriously restricts the follow-up research work

Abstract

The invention provides a separation and culture method of primary human retina Muller cells. The separation and culture method comprises the following steps: (1) a normal eyeball surgically excised from a corneal donor is taken out aseptically; (2) under a dissecting microscope, retina tissue is detached aseptically; (3) mixed collagenase is added for digestion; (4) digestion is terminated, filtering, centrifuging and washing are conducted, re-suspending is conducted through a complete medium, and the complete medium is inoculated into a culture bottle; (5) the culture bottle is placed into a5% CO2 incubator at 37 DEG C to be cultured; (6) cell passage and purification are conducted; and (7) the cell morphology is observed and identified. According to the separation and culture method ofthe human retina Muller cells, operation is easy, stability and high efficiency are achieved, and a good experimental material is provided for further studying a retinopathy damage generation mechanism.

Description

technical field [0001] The invention belongs to the technical field of cell culture of modern biotechnology, in particular to a method for separating and culturing human retinal Muller cells. Background technique [0002] Muller cells were first described by German Müller (1851) and named after him. Because of its elongated shape, it is also called Muller fiber. Its cell body emits slender protrusions to the inside and outside, occupying the entire thickness of the retina from the inner limiting membrane to the outer limiting membrane, surrounding most of the cones, rods, bipolar cells and ganglion cells in the retina, and specialized foot plates Attached to the retinal capillary wall to participate in the formation of the blood - retinal barrier. Muller cells are the main glial cells in the vertebrate retina. It runs through the entire retina and interacts with retinal nerve cells and retinal blood vessels in multiple functions. The pathogenesis of diabetic retinopathy ...
