分裂球

Of or relating to a blastomere.

属于或关于分裂球的。

A blastomere of intermediate size ,larger than a micromere but smaller than a macromere.

中分裂球中等尺寸的分裂球，大于小分裂球而小于大分裂球

In this study, we found interesting two-cell stage embryos, which had a monopolar spindle in one blastomere and a bipolar spindle in the other during the second mitosis in a batch subjected to tetraploidization treatment.

在诱导四倍体过程中，我们发现了有趣的二细胞期胚胎现象，在第二次有丝分期间，它的一个分裂球中有一个单极纺锤体，二另一个有一个双极纺锤体。

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。

Interestingly, a monopolar spindle was assembled in each blastomere in the second cell cycle, and disjunction of duplicated chromosomes and the cleaage was preented, leading to the chromosome set doubling.

有趣的是，在第二个细胞周期中，每一个分裂球中都组装了一个单极纺锤体，同源染色体分离和卵裂被阻止，导致染色体组加倍。

The reprogarmming of embryonic genome is likely the molecular foundation of the transition of highly differentiated oocytes into totipotential embryonic blastomeres.

基因表达的&再程序化&可能是高度分化的卵母细胞转变成胚胎中具发育全能性分裂球的分子基础。

PKC isoform was typically concentrated around the condensed chromosomes before the MI stage, but localized in the pronuclei of zygotes and the nuclei of blastomeres of early embryos.

PKC亚形集中在MI期前浓缩的染色体周围，也位于受精卵原核或早期胚胎分裂球的核。

The bioactivity of bFGF released from PLGA microspheres are higher than from PELA.(2) the bFGF released from PLGA microspheres can stimulate mitosis, proliferation, and matrix synthesis of chondrocyte more effectively than free bFGF. 10 days later after the administration of PLGA microspheres, the effects of stimulus to synthesis of type Ⅱ collagen and proteoglycan can be compared with continue administration of free bFGF.

游离bFGF对软骨细胞的促有丝分裂的作用效应期短；bFGF缓释微球能通过持续释放活性bFGF，在较长时期内促进软骨细胞的分裂增殖；Ⅱ型胶原免疫荧光测定和蛋白多糖阿新兰染色测定显示，应用微球10天后，能有效的促进软骨基质成分的合成，其效果与持续应用游离bFGF的效果相当。

The bioactivity of bFGF released from PLGA microspheres are higher than from PELA.(2) the bFGF released from PLGA microspheres can stimulate mitosis, proliferation, and matrix synthesis of chondrocyte more effectively than free bFGF.

游离bFGF对软骨细胞的促有丝分裂的作用效应期短；bFGF缓释微球能通过持续释放活性bFGF，在较长时期内促进软骨细胞的分裂增殖；Ⅱ型胶原免疫荧光测定和蛋白多糖阿新兰染色测定显示，应用微球10天后，能有效的促进软骨基质成分的合成，其效果与持续应用游离bFGF的效果相当。

Then PLGA Micro spheres can promotes the proliferation of osteoblast in a long perlod because of the controlled release of bFGF from microspheres. The PELA microspheres satisfied the proprty reguirement of controlled release, but the biological activity of the released bFGF is partially destroyed.

2体外细胞试验中，游离bFGF对成骨细胞具有促分裂增殖的作用，但效应期很短；而PLGA微球通过持续释放活性bFGF，可在较长时期内促进成骨细胞的分裂增殖；PELA微球虽然达到了缓释的性能要求，但释放出的bFGF的生物活性受到了破坏。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
