【目的】研究家兔子宫平滑肌层细胞的体外培养和扩增方法。【方法】应用酶解消化法对新西兰大白兔的子宫平滑肌细胞进行体外分离和培养,并研究不同水平性腺激素对其生长的影响。【结果】酶解消化法可成功进行家兔子宫平滑肌细胞的体外培养和传代。子宫平滑肌细胞在体外的增殖受卵巢性腺激素的影响,100 nmol/L雌二醇对其体外增殖有促进作用,而100 nmol/L孕酮则有抑制作用。免疫组织化学结果表明,体外培养的子宫平滑肌细胞在激素作用下仍可维持其特性,在体外可传9~10代。【结论】建立了家兔子宫平滑肌细胞的体外培养和扩增方法,可为构建子宫三维结构提供充足的种子细胞。 |

Abstract: |
【Objective】This study investigated the isolation and culture of uterine myometrial cell in vitro.【Method】In this study,tissue isolation and trypsin digestion method was used to isolate and culture uterine myometrial cell from New Zealand White rabbits in vitro,and effects of β-estradiol (E2) and progesterone (P4) levels on the proliferation of myometrial cells were investigated.【Result】The uterine myometrial cells were successfully prepared by tissue cutting and 0.25% trypsin solution digested.The proliferation of the uterine myometrial cells was largely affected by E2 and P4.100 nmol/L E2 increased the proliferation,while 100 nmol/L P4 inhibited the proliferation (P<0.05).Immunocytochemistry staining demonstrated that the uterine myometrial cells could maintain their behaviors with the help of hormones for 9-10 generations in vitro.【Conclusion】The established culture and proliferation of uterine myometrial cells could provide enough seeding cells for the construction of 3D uterine structure. |
