Abstract
Objective: To establish a model of endometriosis in immunodeficient nude mice and compare the outcome of the model construction between two different techniques. Methods: Eighteen nude mice were divided into 2 groups, with 9 mice in each group. All nude mice received a subcutaneous transplantation of endometrial fragments, followed by sutured the wounded skin (sutured group) or not (no-sutured group). Then the success rate of the model construction, inflammation of the wounds and the animal survival rate in the two groups were analyzed. Result: In no-sutured group, the survival rate of animal and the success rate of the model construction were 9/9 and 8/9 respectively, with 8/9 survival rate and 7/9 success rate in sutured group. No significant difference was found between the two groups. And no obvious inflammation was presented in the wounds for both groups. Conclusion: It is an effective method to establish animal model of endometriosis by subcutaneous transplantation in nude mice. After transplantation, it does not affect the outcome of the survival rate of the animal and the success rate of the model construction whether we suture the wounded skin. Considering the shorter operation time, we found it's a simpler and time saving method to establish endometriosis by subcutaneously transplanting endometrial fragments in nude mice with no skin-sutured. And this model is worth of promotion.
