Results:LIF improved the development rate of early embryo at the concentration of 0.1,1 and 10ng/ml(P.05).The enhanced effects of LIF were significant for morula and blastocyst stage,not for 1～8 cell stage of embryos.Conclusion:LIF may improve the development of early mouse embryos at the appropriate concentration.

結果：①0.1ng/ml人人干人人操人人上人人搞、1ng/ml和10ng/ml濃度的LIF對小鼠早期胚胎的發(fā)育和胚泡的形成有促進作用，0.01ng/ml和100ng/ml濃度的LIF對胚胎的發(fā)育無明顯影響日韩一级A片在线高清视频；②LIF對小鼠早期胚胎發(fā)育的影響主要發(fā)生于桑椹胚和胚泡期亚洲欧美在线等，對1～8細胞期胚胎無明顯影響。

Addition of 3μg/ml CB to CM containing 0.625μg/ml CHX increased the proportion of oocytes with two pronuclei (38. 9% vs 15. 1%, P＜0.05) and developed into morulae/blastocysts (40.7% vs 26. 8%, P＜0.05), but did not affect the percentage of oocytes cleaved and total pronucleus rate.

Our study includes four aspects. In the first aspect we study several important conditions of porcine oocytes maturation in vitro and oocytes cleavage after parthenogenetic activation and found mNCSU-23+15IU/mlPMSG+20IU/mlHCG+15% PFF+0.57mMcysteine is a good culture condition .When the Cocs are cultured in it ,the maturation rate and oocytes cleavage rate are higher than those of foreign covered. Our result are (86.7±3.35)% and (86.3±4.16)% and the highest report of foreign is(85.7±4.1)%.In the second aspect we study the effect of different chemical activations on development of porcine parthennogenetic embryo and found two best activation method. The first one is that putting the maturation MII oocytes in the 20μmol/L ionomycin for 30 minutes and then putting them in the NCSU-23 condition containing 5μg/mICB and 5mM/L6-DMAP for 3.5 hours, the oocytes cleavage rate and morulae/blastocysts development rate are (76.7±7.6)% and (37.1±6.4)%.The second one is that putting the maturation MII oocytes in the 200μM/L Thimerosal for 20 minutes and then putting them in the NCSU-23 condition containing 8mM DTT for 30 minutes

本研究分為4個部分，第一部分對影響豬卵母細胞體外成熟和孤雌激活后胚胎分裂的幾個重要條件進行了比較研究永久免费视频在线观看色黄，確立了一種較好的培養(yǎng)方法：與顆粒細胞共培養(yǎng)婷婷五月丁香在线，找到了一種適合豬卵母細胞體外成熟的培養(yǎng)基：mNCSU-23+15IU/mlPMSG+20IU/mlHCG+15%PFF+0.57mM半胱氨酸，成熟率和分裂率分別為(86.7±3.35)%和(86.3±4.16)%99精品综合加勒比在线观，國外報道的最高成熟率為(85.7±4.1)%亚洲欧美色图13p；第二部分對豬卵母細胞孤雌激活的化學方法進行了研究，確立了化學激活豬卵母細胞的兩種最佳方法：1將成熟的去卵丘顆粒細胞的MII期卵母細胞用20μmol/Lionomycin作用30min欧洲免费AV在线网站观看，再將卵母細胞培養(yǎng)于含5μg/mlCB和5mM/L 6-DMAP(6-二甲基氨基嘌呤)的NCSU-23培養(yǎng)液中国产综合视频网，卵裂率和桑囊胚發(fā)育率達到(76.7±7.6)%和(37.1±6.4)%2將成熟的去卵丘顆粒細胞的MII期卵母細胞在200μM/L的Thimerosal中處理20min，再與8mM的DTT共孵育30min国内妇人成熟A片免费看，卵裂率和桑/囊胚形成率為(81.0±2.8)%和(39.6±2.7)%亚洲第一区在线观看；第三部分對孤雌激活胚胎的培養(yǎng)條件進行了研究，確立了一種最佳的胚胎培養(yǎng)條件：在SOF簡單培養(yǎng)基中添加顆粒細胞進行前3天的培養(yǎng)亚洲无码2019，然后轉入添加胎牛血清的NCSU—23培養(yǎng)基并和輸卵管上皮細胞進行后期的培養(yǎng)亚洲高清无码91，其桑椹胚和囊胚的發(fā)育率為(59.5±3.2)%；第四部分研究了IGF-I
