preparation example Construction
[0054] The present application also provides a preparation method of the above-mentioned gynecological gel, comprising:
[0055] Adding the exosome solution and Cnidium Fructus Extract to the gel solution for the first stage of stirring;
[0056] Add berberine and matrine to the mixed solution, carry out the second-stage stirring, and obtain the gynecological gel after the stirring is completed.
[0057] Preferably, the exosomes are extracted from stem cells treated with hypoxia, and the oxygen concentration of the hypoxia treatment is 5%-10%.
[0058] Preferably, the oxygen concentration of the hypoxic treatment is 5%.
[0059] Hypoxia treatment stimulates stem cells to secrete more exosomes, and can make stem cells secrete more cytokines, increasing the number of cytokines contained in exosomes, so that exosomes have better therapeutic effects.
[0060] Preferably, the extraction method of exosomes includes: any one of differential high-speed centrifugation, density gradie...
Embodiment 1
[0066] 1.1 Preparation of exosomes
[0067] 1.11 Isolation and culture of human amniotic mesenchymal stem cells
[0068] Take the amniotic membrane after cesarean section, wash the amniotic membrane with DPBS containing 1% double antibody (DPBS solution contains penicillin 100U / ml, streptomycin 0.1mg / ml), and use tissue scissors and tweezers to remove coagulated blood clots and excess organize. Cut the amnion into pieces with tissue scissors, add 0.5% trypsin and shake and digest at 37°C for 1 hour, then filter the digested tissue through a 200-mesh sieve, wash thoroughly with the above-mentioned DPBS containing 1% double antibody, and then place Tissue fragments were collected and digested with 1 mg / ml collagenase 1 at 37°C for 1 h with shaking. Filter the digested tissue through a 200-mesh sieve, take the filtrate, and centrifuge at 1500 rpm / min for 5 min to collect the cell pellet. Resuspend the cell pellet in DMEM / F12 medium and culture at 37°C, 5% CO 2 In the cell cul...
Embodiment 2
[0079] The difference from Example 1 is that the exosomes of the gynecological gel in Example 2 come from normal cultured human amniotic mesenchymal stem cells that have not undergone hypoxic treatment, and the rest of the steps are the same as in Example 1, and will not be repeated here.
