Problems solved by technology

After a large amount of literature research, we found that most of the current research is limited to the improvement of DPCs culture methods, and has not conducted in-depth research on the DPCs microenvironment, which is an important factor affecting the maintenance of normal biological functions of DPCs in vitro

Embodiment Construction

[0050] The technical solutions of the present invention will be further described below through specific embodiments.

[0051] Unless otherwise specified, various raw materials and equipment of the present invention can be purchased commercially, or prepared according to conventional methods in the technical field.

[0052] The whole process of preparation is strictly required to be aseptic, and all the instruments used need to be sterilized by high temperature, high pressure or gas.

[0053] The construction method of the bionic three-dimensional DPCs independent culture system of this embodiment is as follows:

[0054] (1) Cell source: Using fresh hair follicle units from patients undergoing FUE hair transplantation, wash the hair follicle units extracted during the operation with PBS, cut off the hair follicles at 1-2 mm from the lower edge of the sebaceous gland under a stereoscope, take the lower part of the hair follicles, and pass through After digestion with 0.1% neut...

Abstract

The invention discloses a bionic three-dimensional DPCs independent co-culture system and a construction method thereof, comprising the following steps: preparing DPCs, DSCs and HGMCs single-cell suspension; providing Matrigel, adding DPCs single-cell suspension to Matrigel, and resuspending to form Matrigel- DP cell suspension; make the Matrigel-DP cell suspension adhere to the microporous membrane of the Transwell chamber to obtain a three-dimensional DPCs culture system; inoculate HGMCs in the upper chamber of the Transwell chamber of the three-dimensional DPCs culture system, and inoculate DSCs in the lower chamber at the same time , and then add the medium to prepare a bionic three-dimensional DPCs independent co-culture system. The invention can effectively simulate the microenvironment of DPCs in vivo, reduce the difference between DPCs cultured in vitro and normal DPCs in vivo, and maintain the biological function of DPCs in vitro for a long time.

Description

technical field [0001] The invention relates to the technical field of three-dimensional cell culture, in particular to a method for constructing a bionic three-dimensional DPCs independent co-culture system and a method for cultivating the bionic three-dimensional DPCs independent co-culture system. Background technique [0002] Hair follicles contain dermal components (dermal papilla cells (DPCs), dermal sheath cells (DSCs)) and epidermal components (hair matrix cells (HGMCs), hair follicle stem cells, inner root sheath cells and outer root sheath cells). Among them, DPCs in the dermis play a key role in hair follicle morphogenesis and cycle, and are the core seed cells in hair follicle tissue engineering. The research on the biological function of DPCs is the key research direction of hair follicle tissue engineering. Although DPCs are similar to fibroblasts in origin, there are essential differences between them. First, DPCs express their own specific markers (ALP, Ve...
