Embodiment 1

[0032] Embodiment 1: Effect of crocin II on growth of mouse hair follicles and proliferation of hair follicle bulb cells in vitro

[0033] 1. Preparation of saffron decoction

[0034] Take 40g of saffron (purchased from Beijing Tongrentang Pharmaceutical Co., Ltd.), soak in 400mL of distilled water for 1h, decoct in a ceramic decocting pot for 40min, pour out the medicinal liquid, add 200mL of distilled water to the medicinal residue and decoct for 20min, and combine the two decoctions , concentrated to 200mL over low heat, so that the concentration of the saffron peanut medicine in the liquid medicine was 0.20g / mL, adjusted to a pH value of about 7.4 after suction filtration, sterilized by high-pressure steam, and stored at 4°C for later use.

[0035] 2. Main experimental materials

[0036] C57BL / 6J mice (provided by the Institute of Animals, Chinese Academy of Medical Sciences), crocin II with a purity of 99% (Sigma Company), Williams culture medium, isolate enzyme and type I...

Embodiment 2

[0062] Example 2: Effect of crocin II on the Wnt / β-catenin signaling pathway of human scalp hair follicle tissue in vitro culture

[0063] 1. Main reagents and medicines

[0064] Crocin II purity 99% (Sigma Company); rabbit anti-human Wnt3a monoclonal antibody, rabbit anti-human β-catenin monoclonal antibody, β-actin (Sigma Company), RPM11640 medium (Sigma Company).

[0065] 2. Main experimental steps

[0066] (1) Take the discarded human scalp hair follicles after hair transplantation (the patient has signed the informed consent), put the isolated specimens into a sterile centrifuge tube filled with normal saline immediately after obtaining the hair follicles, and separate the hair follicles under a microscope. The posterior hair follicle tissue was moved to a new PBS culture dish and washed three times with fresh PBS. Carefully aspirate the PBS wash solution under the microscope with a 2 mL pipette.

[0067] (2) Crocin II is dissolved with serum-free RPM11640 culture flui...

Abstract

The invention provides application of crocin II in preparation of a medicine for preventing and treating alopecia by acting on hair follicle tissues. The invention also provides application of the crocin II in preparation of a medicine for improving the activity of the hair follicle tissues. The medicine is directly smeared or sprayed onto the scalp to promote hair follicles in a resting period toenter a regeneration period and promote hair growth. The invention also provides application of the crocin II in preparation of a medicine for improving the activity of hair follicle tissues culturedin vitro. The crocin II is prepared into a tissue culture solution to act on the hair follicle tissues cultured in vitro, so that the microenvironment of the hair follicle tissues is improved, the hair follicle tissues in the resting period and a degeneration period are promoted to be converted into hair follicle tissues in a growth period, the activity of the cultured hair follicle tissues is further improved, and the survival rate of transplanted hair follicles is remarkably increased.

Description

technical field [0001] The invention belongs to the field of medicine and relates to a new application of crocin II, in particular to the application of crocin II in preparing a medicine for preventing and treating hair loss by acting on hair follicle tissue. Background technique [0002] Hair and hair are keratinized filamentous structures that grow on the skin surface of the whole body, and are appendages derived from the epidermis. Hair and hair are unique to mammals. Human hair has been quite degenerated, but hair follicles are rich in nerve endings and are sensitive touch receptors. At the same time, human hair affects people's appearance and has important social significance. [0003] Studies have shown that hair follicles are formed during embryonic development and undergo repeated cycles of growth (Anagen), regression (Catagen) and rest (Telogen) after birth. In the growth phase, the hair mother cells (Matrix) rapidly proliferate and differentiate into the hair sha...
