[摘要] 目的 利用改進后的EBSS（SIGMA）培養液和常用商品化培養液G1/G2（Vitrolife），Quinns1026/Quinns1029（SAGE）對昆明系小白鼠胚胎進行體外培養，以對新建IVF實驗室進行評估。 方法 對簡單培養液EBSS進行改進，分別制得卵裂培養液和囊胚培養液以構成序貫培養系統。卵裂培養液： EBSS中加入適當濃度的丙酮酸鈉，乳酸鈉以及5種非必須氨基酸；囊胚培養液： EBSS中加入適當濃度的5種非必須氨基酸及6種必須氨基酸。將胚胎分成4組，A組使用EBSS （Earles Balanced Salt Solution）培養液，B組使用改進后的EBSS培養液，C組使用G1和G2培養液，D組使用Quinns1026和Quinns1029培養液，四種培養液均添加10%人血清白蛋白。結果 72 h后，鼠胚總體囊胚形成率為70.57%（614/870），其中A組的囊胚形成率為26.21%（27/103），B組為72.22%（143/198），C組為73.81%（155/210），D組為80.50%（289/359）B，C，D 3組的囊胚形成率顯著高于A組（P<0.001）。 結論 通過鼠胚體外培養，對新建試管嬰兒實驗室進行了較好的質控檢測，經改進后的EBSS培養液在鼠胚囊胚形成率上與商品化序貫培養液G1/G2，Quinns1026/Quinns1029相近，均遠高于簡單培養液EBSS，但前者成本較之常用商品化試劑有大幅度的降低，說明改進的EBSS培養液在鼠胚體外培養上具有較好的實用價值。

[Abstract] Objective Using improved EBSS（SIGMA） culture media and common commercial media G1/G2（Vitrolife） and Quinn's1026/Quinn's1029（SAGE） to culture mouse embryo of Kunming species in vitro for the assessment of a newly constructed IVF laboratory. Methods Modifying simple culture media EBSS by adding proper concentration of sodium pyruvate， sodium lactate and 5 nonessential amino acids to make cleavage stage media and adding proper concentration of 5 nonessential amino acids and 6 essential amino acids to make blastocyst stage media. 2-cell mouse embryos with normal morphology were collected and divided into 4 groups. Group A was cultured in EBSS （Earle's Balanced Salt Solution）， Group B was cultured in improved EBSS media， group C was cultured in G1/G2， group D was cultured in Quinn's1026/Quinn's1029， and each media was added with 10% human serum albumin （HSA）. Results The general blastocyst formation rate of mouse embryo at 72 h was 70.57%（614/870）. The blastocyst formation rate of group A was 26.21%（27/103）， that of group B was 72.22%（143/198）， that of group C was 73.81%（155/210） and that of group D was 80.50%（289/359）. Compared with group A， the blastocyst formation rate of group B， C and D was significantly higher， respectively （P<0.001）. Conclusion The mouse embryo culture in vitro served as a target to assess the quality control for a newly constructed IVF laboratory. Using improved EBSS media achieved similar mouse blastocyst formation rate compared with the common commercial media G1/G2 and Quinn's1026/Quinn's1029， which were significantly higher than simple media EBSS. However， the cost for improved EBSS media was much lower than common commercial media which means the improved EBSS media was superior for the development of mouse embryos in vitro.
