多向

To sum up, we first conclude that we can isolate mesenchymal stem cells from human fetal articular cartilage and they can be induced to differentiae into several cells under appropriate induction conditions. Anymore, they have their original tissue speciality. Therefore, we first report that mesenchymal stem cells of articular cartilage origin are superior to mesenchymal stem cells of bone marrow origin as seeding cells of cartilage tissue engineering and we provide a kind of new seeding cells of cartilage tissue engineering for the future clinic application.

综上所述，我们首次报道不仅可从人胚胎的关节软骨中获得间充质干细胞，而且软骨来源的间充质干细胞除具有骨髓来源的间充质干细胞的多向分化能力外，还具有其来源的软骨组织特异性，那么，其作为软骨组织工程的种子细胞要优于骨髓来源的间充质干细胞，从而首次提出了一种新型的软骨组织工程的种子细胞，对于未来的软骨组织工程的临床应用提供理论依据。

BACKGROUND: Bone marrow mesenchymal stem cells are capable of multiple directional differentiation, and are potential cells and target cells for gene therapy.

BACKGROUND: Neural stem cells have the potential of self-proliferation and multiple directional differentiation, and can differentiate into various cells in the neural system under a certain condition.

摘要背景：神经干细胞具有自我增殖能力和多向分化潜能，一定条件下可以分化成神经系统的各种细胞，因此在神经损伤修复方面有着良好的应用前景。

BACKGROUND: Extract of astragalus mongholicus has good effects on antioxidization and oxygen free radical scavenge. Bone marrow mesenchymal stem cells have multiple directional differentiation potential and superiority of autologous transplantation. This can provide a new way for treating neurodegenerative diseases.

背景：黄芪提取物有较好的抗氧化、清除氧自由基的作用，加之骨髓间充质干细胞的多向分化潜能及其自体移植的优越性，可能为神经退行性疾病的治疗提供新的方式。

The low teaching performance of the teachers resulted the low quality and the disparagement of the teachers\' and students\' life.

本文的基本观点是：虽然影响教师教学效能的因素很多，这些因素又多向度地相互作用使得教学效能非常复杂。

Most researchers reported that neuroendocrine cell's were the results of stem cell's multi-directional differentiation, like epithelial cell, which is originated from endoderm multipotential stem cells.

多数研究认为，神经内分泌（neuroendocrine，NE）细胞和上皮细胞均来自内胚层多潜能干细胞，是肿瘤发生过程中干细胞多向分化的结果。

Objectives: Being able to simultaneously express all genes of germline, endoderm, mesoderm and ectoderm, bone marrow mesenchymal stem Cells are considered to have the potential to differentiate to other tissues and cell lines.
