查询词典 differentiation operator

The protoxylem vessels initiated lignification in the early stage of vascular bundle differentiation, whereas metaxylem vessels and fiber walls started lignification from the middle lamella and cell comers after completion of vascular bundle differentiation. The walls of most parenchyma cells lignified after the stem reached its full height, while a few parenchyma cells remained non-lignified even the culm is 7 years old.

研究结果表明：毛竹茎的原生木质部导管在维管束发育早期就已木质化；后生木质部导管和纤维细胞在维管束分化完成后，自胞间层和细胞角隅处开始木质化；基本薄壁组织细胞木质化的发生较晚，通常在茎的节间完成伸长生长后才开始，但也有少数薄壁组织细胞始终保持非木质化的薄壁状态。

He type of ossein in group B was mainly type Ⅰ collagen while that in group A type Ⅱ and it exhibited as a process of fiber formation in group C. The reason for why TGF-β〓 can promote ossification induced by BMP is that can promote the differentiation and proliferation of mesenchymal cells to supply more target cells for BMP, promote the differentiation and proliferation of mature osteocytes and chondrocytes, inhibit metalloproteinase to decrease the destruction of bone tissue and promote calcification of bone matrix.

GF-〓能促进BMP骨诱导作用主要因其能促进间充质细胞的分裂增殖为BMP提供丰富的靶细胞、促进成熟骨及软骨细胞的分裂增殖、促进骨细胞产生Ⅰ型胶原而抑制软骨细胞产生Ⅱ型胶原，抑制金属蛋白酶的活性以减少组织破坏、促进基质钙化等作用而使骨生成能力增加，提示它和BMP具有协同作用。

At the cellular level, As〓O〓 triggers apoptosis and a partial differentiation of APL cells in a dose-dependent manner, that is, triggering apoptosis at relatively high doses (0.5-2μM) and inducing partial differentiation at low concentration (0.1-0.5μM) after relative long time treatment.

体外研究发现，在细胞水平，As〓O〓可诱导早幼粒细胞凋亡与部分分化并呈剂量依赖性，即大剂量(0.5-2μM)As〓O〓诱导APL细胞凋亡，而低剂量(0.1-0.5μM)As〓O〓长时间作用后则诱导APL细胞部分分化。

Results: The proliferation of Kasumi-l cell was obviously inhibited by VPA on dose- and time-dependent manner. The IC50 was 2.33 mmol/L treated with VPA for 72 h. Incubation with VPA, the cell ratio at G0/C1 phase increased. VPA induced myeloid cell differentiation antigen CD11b to increase with a time-and dose-dependent way and caused apoptosis. Wright's staining and light microscope were used to show the morphology of partial differentiation and obvious apoptosis with 3 mmol/L VPA for 72 hours. The typical DNA ladder of apoptosis characteristic was observed with DNA gel electrophoresis.

结果：VPA能显著抑制Kasumi-1细胞的增殖，且呈剂量和时间依赖性，VPA处理Kasumi-1细胞72h时的半数抑制浓度(IC50)为2.33 mmol/L；VPA处理后，细胞周期检测G0/G1期细胞比例逐渐增高；VPA能诱导髓系分化抗原CD11b表达水平的阳性率升高，呈时间及剂量依赖性；VPA能诱导Kasumi-1细胞凋亡，Kasumi-l细胞经VPA3 mmol/L处理72h后，出现典型的凋亡细胞所具有的梯形DNA条带。

Differentiation of the protoderm layer marked the beginning of the structural differentiation in globular stage.

球形胚时期表皮原层的分化标志着体细胞胚结构分化的开始。

The results showed that PYM could dramatically inhibit callus induction and differentiation of explants. With the increasing of PYM concentration, hoth the callus induction rate and differentiation rate decreased.

结果表明，PYM对叶片和茎段愈伤组织的诱导和分化具有明显的抑制作用，随着PYM质量浓度的增加，愈伤组织的诱导和分化均呈明显的下降趋势。
