Our data support the notion that human follicle development can be achieved in vitro in a bio-engineered culture system.

结论我们的数据表明，人类卵泡在体外生物工程培养体系中是可以发育的，但仍需要更多的研究进一步揭示体外培养卵泡是否获得充分大小的卵母细胞，而且卵母细胞是否有能力恢复减数分裂和受精。

The mitotic error rate in cleavage stage embryos was proven to be higher than the meiotic aneuploidy rate and as a consequence, the genome of a single blastomere is not representative for the genome of the other cells of the embryo.

在卵裂期胚胎这种有丝分裂的错误率被证明是高于减数分裂的非整倍体错误率，因此，单个卵裂球的基因不能代表其他胚胎细胞的基因组。

Meiotic pachytene bivalents were obtained from porcine testes using prolonged hypotonic treatment combined with high chloroform Carnory's fixative solution. Mitotic metaphase chromosomes were prepared from blood cell culture. Comparative studies on division index and length of pachytene bivalents and mitosis metaphase chromosomes showed that those of the former are 5 times higher and 3.42(1.87～5.98) times longer than the latter, respectively. Chromomere maps of bivalents are more abundant than mitotic metaphase G-bands, while they are correspondent with mitotic early-metaphase G-bands. The result was found by using the chromosome 12 as a sample.

以性成熟公猪睾丸和外周血为材料，采用长低渗、高氯仿卡诺固定液固定和外周血细胞培养制备减数分裂粗线期二价体和有丝分裂中期染色体，通过对二价体和有丝分裂中期染色体分裂指数和长度的比较研究，发现二价体的分裂指数和长度分别是有丝分裂中期染色体的5倍和3.42倍(1.87～5.98)；同时以12号染色体为例，比较了二价体上的染色粒结构带与有丝分裂中期染色体G-带，表明染色粒结构带比中期染色体G-带带纹丰富，而与早中期G-带带纹吻合。

Due to the deficiency of cyclin B1 and 〓, spermatogonia and pachytene/diplotene primary spermatocytes in contralateral cryptorchid testis were unable to form MPF, and therefore, they could not accomplish their nuclear division, and became arrested at the transition stage from mitosis to meiosis (G2/M phase). We also found that testosterone could regulate the cyclin B1 expression in spermatogenic cells.

由于cyclin B1和〓的缺失，粗线期/双线期初级精母细胞中的MPF无望形成，从而导致生精细胞分裂停滞在由有丝分裂向减数分裂过渡的G2/M相；（5）睾酮可在翻译水平上调控阴囊内睾丸生精细胞cyclin B1蛋白的表达。

In Peiai 64S, the microtubules showed abnormal patterns of distribution from pre_meiotic interphase to metaphase Ⅰ. For example the broad band of perinuclear microtubules seen at diakinesis in IR36 was much disorganized and loosened in Peiai 64S.

(1)在偶线期具极性分布的微管分布不存在；(2 )在小孢子母细胞减数分裂期间的细胞内出现许多特别粗的微管束；(3)在终变期围绕核的微管宽带结构松散及内含微管密度低。

The journal covers the research advances of the dynamics and mechanisms of sexual processes in all plants, including meiotic mechanisms, male and female gametogenesis and their related gene expression, fertilization mechanisms, gamete recognition, control of early embryogenesis and biotechnological applications in sexual reproduction etc.

该杂志涵盖了所有植物有性繁殖过程的动力学与机制的研究进展，包括减数分裂机制、雌雄配子形成与它们相关的基因表达、授精机制、偶合子识别、早期胚胎形成控制以及生物技术在有性繁殖中的应用等等。

The heterozygote genotypes in F2 population in this type of species are different from those in general species in which the genetic recombination occurs in meiosis of both male and female.

这类物种的杂交F2群体中杂合子基因型的与一般物种中雌雄个体的减数分裂细胞都发生遗传重纽的F2群体杂合子表型不同。

Maxillary teeth were retracted,and the overjet and overbite were adjusted to right relations,and soft convex tissues face type was improved.

上颌牙齿前突减数矫治，有助于上颌和上牙弓的突度减小，使软硬组织面型之间的形态结构一致，特别对上牙弓突度的改善是肯定而持续的。

Megaspore mother cells undergo meiosis, which results in the formation of 4 megaspores in a row. The chalazal-most cell develops into an 8-nuclei embryo sac after 3 rounds of mitosis. A mature embryo sac is produced after cellularization and nuclear migration.

结果表明：1大孢子母细胞经过减数分裂形成直线排列的4个大孢子，其中珠孔端的3个大孢子退化，合点端的大孢子进行3次有丝分裂，形成八核胚囊， 8个核迅速细胞化，最终发育为成熟胚囊。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
