Abstract

The invention relates to an isolated culture method for primary generation rabbit melanophore. According to the method, the rabbit melanophore is isolated through an enzyme digestion method, and after culturing is conducted through an M254 complete medium, an M254 / HMGS culture medium is adopted through replacement for culturing till the convergence degree reaches 80%-90%, then a differential digestion method is utilized for removing other cells, and the purified melanophore is obtained. The purity of the melanophore is greatly improved, the cultured cells are identified through cell morphologic observation, L-DOPA staining, semiquantitation and an anti-S-100 immunocytochemical staining method, the result shows that the isolated primary generation melanophore is mostly in a dendritic shape and a thin and long shuttle shape, the brownish black is shown after L-DOPA staining, the RT-PCR analysis shows that the isolated cells express the marker gene of the melanophore, and the S-100 staining cytoplasm is brown.

Description

technical field [0001] The invention relates to the fields of cytogenetics and molecular biology, in particular to a method for separating and culturing rabbit melanocytes in vitro. Background technique [0002] Mammalian skin and coat have a variety of colors, which are caused by chemically stable melanin, which can be divided into pheomelanin and eumelanin, which are oxidized by tyrosine or related components under the catalysis of corresponding enzymes. into. Inherited genes control the formation and type of coat color pigments that determine the coat color of mammals. As an important fur animal and experimental model, rabbits are also very rich in fur colors, including black, gray, yellow, blue and other natural colors, without printing and dyeing, and are favored by consumers. However, due to the difficulties in live animal experiments and the lack of suitable cell models, it has seriously hindered people's research on the genetic mechanism of rabbit coat color. This...
