Stem cells which exist in the individual life are the cell population with high self renewal capacity and multiple differentiation potential. 干细胞是个体生命过程中产生和存在的具有高度自我更新能力和多向分化潜能的细胞群体。
Recently, Studies of stem cells have suggested the existence of another kind of stem cells, besides of embryonic ones, which have the ability of self-renewing and differentiation. 近年来研究发现,除了胚胎干细胞,机体内还存在一些组织干细胞,它们具有一定的自我更新和分化能力。
Cytokines such as erythropoietin ( EPO) and thrombopoitein ( TPO) and so on, which stimulate hematopoiesis, can regulate self renewal, proliferation, differentiation, maturation and programmed cell death of hematopoietic cells through specifically binding to surface receptors. 能刺激造血的细胞因子如红细胞生成素(EPO)和血小板生成素(TPO)等通过与其受体的特异性结合来调控造血细胞的自我更新、增殖、分化、成熟及程序性死亡。
AIM: To investigate the repairing effect of proliferation and transplantation of neural stem cells ( NSCs) on brain injury in rat model of traumatic brain injury ( TBI) according to the characteristics of self renewing and multi differentiation of NSCs. 目的:基于神经干细胞的自我更新和多向分化的特点,探讨创伤性脑损伤(traumaticbraininjury,TBI)后神经干细胞(NeuralStemCells,NSCs)的增殖及其移植对脑损伤的修复作用。
Stem cell is an ideal target cell with the ability of self renewing and multi differentiation, and can proliferate and keep multi differentiation potential when it is suitably cultivated in vitro. 干细胞具有自我更新,多向分化能力,在适宜的体外培养中干细胞能够稳定生存增殖并保持多向分化潜能,是便于体外操作的理想的靶细胞。
From which to explore how Japan as a special "The other" acting on the construction of nation self ( in the broad sense) and lead to identity differentiation. 从中探究日本这一特殊的他者是如何作用于建构民族(广义上的中华民族)自我时的认同分化。
The market management mode innovation which base on STV Strategy asks for explicit self strategic orientation, strengthen industrial support first; second it asks for devote into differentiation construction, tamp superior foundation; and at last, it requires to develop market brand vigorously. 基于STV战略论的市场经营模式创新要求首先要明确自身战略定位,强化产业依托;其次要致力于市场差异化建设,夯实优势基础;最后要大力发展市场品牌。
【 Conclusion 】 CD44+ integrin. 2.1+ CD133+ cells presented clone generative, self renewal, extensive differentiation ability and higher proliferative potential, i. e stem cell property. 【结论】CD44+整合素·2·1+CD133+细胞具有克隆形成、自我更新、多向分化和强增殖潜能,即干细胞特性。
Youth self-construal in the different gender roles are significant differences, which masculine express more independent self, feminine express more interdependent self, androgynous are reflected in two dimensions, no differentiation is manifested not obvious. 中学生自我构念在不同性别角色上存在显著差异,其中男性化更多地表现出独立自我,女性化更多地表现出互赖自我,双性化在两个维度均有体现,未分化则表现不明显。
