The effects of BMP-2, TNF-α and they two synergism in different concentration were also detected. The mRNA expression of cbfal, OC, H-ras, BMPR-IA, type Ⅰ and typy Ⅱ collagen of ligamental fibroblast under the co-stimulation of BMP-2 and TNF-α were detected using RT-PCR technique.

并分析了不同浓度的人重组骨形态发生蛋白-2（rhBMP-2，10ng/ml、100ng/ml、250ng/ml、500ng/ml）和人重组肿瘤坏死因子-α（rhTNF-α，5u/ml、50u/ml、100u/ml、500u/ml）及两者协同作用（500ng/ml rhBMP-2+50u/ml rhTNF-α）对两类细胞系分化方向（细胞形态变化、ALP活性、DNA及胶原合成、骨钙素分泌）的作用。

It can grow as yeast form, hyphal form and pseudohyphal form.

In the early 1980s, many researchers revealed the structure of cytoskeleton mainly on kinetosome in the cortex by the employment of protargol staining and ultrastructure method, and thus t.

20世纪80年代初，许多学者应用蛋白银染色方法和超微结构方法，显示了纤毛虫细胞皮层中以纤毛基体作为主成分的骨架结构，探讨了纤毛虫皮层纤毛器的形态、形态发生及其结构形成机理，在国内外原生动物细胞学领域成为主流。

Ontogenies of about 60 taxa were typified into 4 morphogenetic patterns, or modes.

主要对3个形态发生区域的阶段形态结构的起源、发育变化和同源性做了研究。

After heat treatment, borides of samples made of sand mould were changed little, otherwise, borides of samples made of metal mould were changed to granulation shape and the impact toughness was increased by 60%..

高硼铁基合金熔体在金属模和砂模不同凝固条件时，奥氏体初晶晶粒随冷却速度增加而减小，硼化物形态发生较大变化；热处理后，砂模铸造的试样，硼化物形态变化不大，而金属模铸造的试样硼化物粒化，其冲击韧度提高了60％。

The interactions in the chimeras can result in changes of phenotypes and improvemany characters, which can be useful for plant breeding.

研究结果发现嵌合体的形态特征在具有了两个亲本特点的基础上，其形态发生了一定变化。

The change of constant KM also indicates the existence of a variety of surface complexes on goethite surface with the increasing of the pH value.

表观吸附常数KM值的变化规律，说明重金属离子与针铁矿表面反应模式及其表面吸附形态发生了变化，具体的吸附形态还有待谱学研究进一步证实
