查询词典 stem cells

目的 建立稳定表达脑源性神经营养因子基因的神经干细胞并观察其对于体外培养的脊髓背根神经节细胞存活及突起生长的影响。

Results: Fujian Tablet could increase the expression of neurotropic factor and decrease that of inhibitory factor. It promoted proliferation, migration, differentiation of neural stem cells, axonal growth and synapse formation remarkably.

结果：复健片可增加神经生长营养因子表达，减少抑制因子表达，对神经元增殖、迁移、分化，轴突延伸、突触形成等有明显促进作用。

Methods: Based on the theory of "kidney produces sui", we set up MCAO rat model. Five indexes including Nestin, PSA-NCAM, MAP-2, GAP-43 and SYN38 were measured in situ hybridization and immunohistochemical methods to evaluate the effects of Fujian Tablet on the proliferation, migration, differentiation of neural stem cells, axonal growth and synapse formation. Other two indexes including trk-B, NOGO-A were used to assess the effects on the neurotropic factor and inhibitory factor.

以&肾生髓&的理论为依据，以MCAO大鼠为实验对象，利用原位杂交技术和免疫组织化学方法，分别以nestin、PSA-NCAM、MAP-2、GAP-43、突触素p38为指标，观察复健片对神经干细胞增殖、迁移、分化、轴突生长、突触形成的影响；分别以trk-B、NOGO-A为指标，观察复健片对神经生长营养因子、抑制因子的影响。

Hematopoietic stem cells are being increasingly for treatment of malignant and nonmalignant disorders.

造血干细胞在许多危重疾病的治疗中有重要作用。

Nucleostemin is a recently discoered nucleolar protein predominantly associated with proliferating rat neural and embryonic stem cells, and some human cancer cell lines.

Nucleostemin是一种最近发现的核蛋白，其主要与大鼠神经源性及胚胎干细胞以及一些人类癌细胞系的增殖有关。

Bone marrow mesenchymal stem cells have odontogenic capacity, but their differentiation abilities significantly decrease with the increasing age of the donors.

骨髓间充质干细胞具有成牙潜能，但是它们的成牙能力随着供体年龄的增长而显著减退，因此上述细胞不适用于老年患者的牙齿再生。

tissue engineering ; osseocartilaginous ; adipose-derived stem cells

近年来，学者们在多个物种的脂肪组织中发现具有多向分化潜能的成纤维细胞样细胞，在体外特定的诱导条件下可以分化为

OBJECTIVE: To investigate the proliferation and osteoblastic differentiation of adipose-derived stem cells induced by calcitonin gene-related peptide in vitro.

目的：探讨降钙素基因相关肽在体外定向诱导脂肪干细胞向成骨细胞增殖分化的可行性。

Recent progress has been made in the identification of the osteoblastic cellular niche for hematopoietic stem cells within the bone marrow.

最近在识别骨髓中造血干细胞的成骨细胞龛方面方面取得了新的进展。

In general, osteoporosis is a disease of bone which is caused by an imbalance between osteoblastic bone formation and osteoclastic bone resorption. However, the recent research showed that the ability of bone marrow mesenchymal stem cells differentiates into adipocytes is greater than osteoblasts and it was thought to cause into osteoporosis, such as diabetes.

骨质疏松症一般被认为是细胞的骨生成作用与破骨细胞的骨吸收作用失去平衡，然而近年来的研究指出骨头内的间质干细胞分化成造骨细胞的能力减弱或是间质干细胞分化成脂肪细胞的能力增强，这样的结果往往会导致骨质疏松症，如糖尿病状态。

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