分裂生长

When optimal levels of growth substances, particularly auxin and cytokinins, are utilized, many species of gesneriads can be generated from a single leaf.

当生长调节物质，尤其是生长素和细胞分裂素的含量适宜时，某些苦苣苔在3～4个月内可由一片叶子再生1000株以上的小植株。

The roots and leaves of the four reed ecotypes were determined for thelevels of abscisic acid and cytokinins using an enzyme linked immunosorbent assay throughout the whole of growing season.

采用酶联免疫吸附法，测定了整个生长季节四种芦苇生态型根和叶组织中脱落酸和细胞分裂素含量的变化。

They were able to be passaged for 15 generations and revealed a 26.562-fold increase of cell numbers over a 10 month period (cumulative population doublings=15 times).

软骨细胞在体外生长良好，在10个月内传代15次，细胞数增加为26.562倍，总分裂次数达15次。

The effects of zinc on c-fos gene expression and transcription in the epiphyses of fetal long bone were studied in mice.

c-fos属于与生长和分化相关的原癌基因(proto-oncogene)，它们的表达是细胞分裂和分化的主要开关。

Actin is a kind of highly conserved protein,existing in all eukaryote.

肌动蛋白是一种高度保守的蛋白质，存在于所有真核细胞中，参与细胞分裂、运动、迁移、形态的维持、生长等多种重要生理活动。

Gelatin microsphere is firstly made by encapsulating bFGF into gelatin by special manufacture process, then this microsphere was combinated into PLGA conduit or PLGA film.when used, we need only pack the injury peripheral nerve, injury spinal cord, wounded pars encephalic with the PLGA conduit. The conduit or film can slowly release buff which would be absorbed by around tissues.bFGF was already proved to be nutritious to the regeneration and alive of neuron and protect injury neuron.bFGF can also promote morphogenesia and division of nerve cell which would raise the survival rate of neuron, guide the generation of axon etc.bFGF is one of the important factors of sustaining the normal survival of cholinergic nerve.

使用时，只需将此材料贴敷外周损伤神经伤患处，脊髓伤口，或在脑部开颅手术后填充于术后创面，可有效地在伤口局部缓慢地释放并由机体组织吸收bFGF等神经营养因子。bFGF等已被证明具有神经营养作用，可促进神经元的再生与存活，保护受损的神经元。bFGF等对神经细胞兼有促进形态发生与分裂作用，具有提高神经元的成活率、诱导轴突向外生长等功能，是维持前脑基底部胆碱能神经元正常生存的重要因素。

The distribution of the growth-associated protein (GAP-43) which is close related to the axon regeneration was examined by immunocytochemical method in the adult rat brain and the rat parietal lobus injuried into which the fetal cerebral suspension was lransplanted.

在发现流式细胞计可用于神经科学的研究后，用FCM研究了大鼠脑发育过程中细胞周期的变化和胚胎大脑细胞移植到成年大鼠顶叶后对宿主顶叶脑细胞分裂的影响；由于生长相关蛋白(GAP-43)与轴突再生密切相关，用免疫细胞化学法研究了GAP-43在成年大鼠脑内的分布及顶叶损伤植入胚胎大脑细胞后GAP-43的变化。

Interleukin-2 is a lymphokine synthesized and secreted primarily by T lymphocyte or T helper lymphocytes that have been activated by stimulation with certin antigens or mitogens.It is one of the important T cell growth factors.

白细胞介素-2(Interleukin-2，IL-2)主要是在促有丝分裂素或特异性抗原刺激下，由T淋巴细胞或T淋巴细胞系产生的一种淋巴因子，是机体主要的T细胞生长因子之一。

BACKGROUND: Basic fibroblast growth factor can accelerate the bone marrow mesenchymal stem cells proliferation and differentiation into nerve cells, which is considered as a mitogen of glial cells.

背景：碱性成纤维细胞生长因子可以促进骨髓间充质干细胞的增殖和向神经细胞方向分化，并被认为是胶质细胞的分裂原。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
