可分裂的

The basidioma is composed mainly of sterile tightly packed hyphae; in most species there is a distinct fertile layer, the hymenium, on the surface of the basidioma that bears the basidial hyphae which, after meiosis, give rise to the basidiospores.

担子果主要由紧密缠绕的不育菌丝组成，多数种类还有明显的可育层子实层，子实层位于担子果的表面，由菌丝形成担子，减数分裂后产生担孢子（参见 basidium

Three kinds of chromosome morphology could be observed under oil immersion lens. The first type was condensed, which could be counted in total, but the band could not be seen. The second type was chromatosome that spread completely in the center of equatorial plate and were in metaphase. In this phase, total numbers and band were seen clearly. Last type-chromosomes had already folded and moved towards two poles and concentrated gradually, the total number of chromosomes could be counted, but banding could not be seen clearly.

在油镜下镜检可见3种染色体形态，一种呈高浓缩状态的染色体，可计数染色体总数，但不能显出带纹；第2种是已完全展开并铺于赤道板上的处于分裂中期的染色体，染色体总数和带纹显示都非常清楚；第3种是染色体已折转并向两极移动，并逐渐开始浓缩，染色体总数可以计数，带纹不能清楚显示。

Sinense, the spores germinate inside their exospores and then divide into massive protonemata;the massive protonemata can form two kinds of protonemata of which one is clubbed protonema with papillae,and the other is caulonema composed of long and cylindrical cells ; the gametophyte archaeocytes only occur on the massive protonemata.

结果表明：中华缩叶藓的孢子在壁内萌发，随后分裂产生块状原丝体；块状原丝体上可产生两种丝状体，一种是具疣的棒状原丝体，另一种是由长圆柱状细胞组成的轴丝体；配子体原始细胞只产生于块状原丝体上。

The two cells that produced by the amicronucleate cell were still without micronucleus.

在整个接合过程中，无小核细胞的大核始终没有发生可观察到的形态学变化，它最终分裂成的二个子细胞仍为无小核细胞。

Analysis of PcG mutants shows that the PcG system represses genes required for anteroposterior, dorsoventral, and proximodistal patterning of imaginal discs and that it also represses cell cycle regulator genes.

对PcG突变体研究发现，PcG系统表达基因在幼虫发育的前端、背腹以及远端模式都是必须的，同时可抑制细胞分裂调节基因的活性。

In this study, a new horizontal microinjection system has been established to solve these problems. Because the average time per pronuclear embryo by microinjection has been significantly shortened with the horizontal system, the cleavage rate and 16-cell rate of those microinjected embryos increased markedly.

为了解决这些问题，本研究有针对性地设计了新型的水平微注射系统，利用此系统，可明显缩短常规注射原核胚的平均时间，注射后原核胚的分裂率、8-16细胞胚胎发育率也明显提高。

Vein transplantation of human UCB-MSCs has protective effects on splenocyte damages induced by irradiation, can promote proliferation and accelerate repair of splenocytes. The action mechanism is associated with elevating natural killer cell activity, and number of CD4+ and CD8+.

脐血间质干细胞静脉输注对辐射造成的脾细胞损伤有一定保护作用，可促进脾脏细胞的分裂增殖，加速脾脏细胞的修复，其作用机制可能与提高NK细胞活性和CD4+、CD8+数量有关。

Both Na2SeO3 and Na2SeO3Vitamin C could obviously inhibit mitoses of vaginal epithelial cells(P＜0.05), but no statistically significance was found between them and the positive control group.

亚硒酸钠及亚硒酸钠-维生素C的各剂量组均可显著抑制小鼠阴道上皮的有丝分裂（P＜0.05），不同剂量的亚硒酸钠组间及亚硒酸钠-维生素C组间与阳性对照组间差异无统计学意义。

The cleavage rate of 2-cell stage was 50%, but few embryos developed into morulas and blastocysts (2%). More than 130 embryos at 2-4-cell stage were transferred into oviduct of 13 synchronized foster rabbits and 2 mice. No fetus or implantation sites were observed in both recipients.

其2—细胞胚胎的分裂率可达50％，但发育至桑椹胚和囊胚阶段的胚胎数目大大减少，只有2％的囊胚发育率。13只受体兔共移植重构胚胎121枚，结果未发现产仔或死胎，仅看到有的兔子宫有於血状。

The apostle deals with the subject of the lamentable divisions and party strifes that had arisen among them 1 Cor.

该书信可分为四个部分：（ 1 ）使徒处理此事的可悲的分裂和党的strifes已出现，其中（ 1肺心病1-4段）。

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。
