Abstract

The invention discloses a cryopreservation resuscitation fluid for ovarian tissues. The resuscitation fluid comprises the following components: (1) a resuscitation solution 1: 90V / V% DPBS, 10V / V% HSA, 0.5-0.8 mol / L sucrose and 5mM N-acetylcysteine; (2) a resuscitation solution 2: 90 V / V% DPBS, 10 V / V% HSA, 0.3-0.5 mol / L sucrose, and 5 mM N-acetylcysteine; and (3) a resuscitation solution 3: 90 V / V% DPBS, 10 V / V% HSA, 0.12-0.3 mol / L sucrose, and 5 mM N-acetylcysteine; during resuscitation, the method comprises the following steps: (1) taking out the cryopreservation tube filled with the ovarian tissue from the liquid nitrogen, and dissolving; and (2) taking out the ovarian tissue from the cryopreservation tube, sequentially adding the ovarian tissue into solutions of the resuscitation solution 1, the resuscitation solution 2 and the resuscitation solution 3, respectively keeping for a certain time, and then putting the ovarian tissue into an eluent for elution to finish resuscitation. The cryopreservation resuscitation fluid can improve the survival rate of resuscitated ovarian tissues.

Description

[0001] This application is a divisional application of Chinese patent application 201810254362.1. [0002] Original application date: 2018.3.26 [0003] Original application number: 201810254362.1 [0004] Invention name of the original application: a cryopreservation protection and resuscitation solution for ovarian tissue technical field [0005] The invention belongs to the field of cryopreservation of ovarian tissue, in particular to a cryopreservation recovery solution of ovarian tissue. Background technique [0006] There are about 4.3 million new cancer patients in China every year, and the five-year survival rate of cancer patients can be as high as 80-90%, and more than 70% of the survivors have urgent needs for fertility. However, while saving the lives of cancer patients, radiotherapy and chemotherapy have caused 70%-100% of the ovarian function is damaged, making it lose fertility, which greatly affects the patient's physical and mental health and family happin...
