The cultured cells appeared morphologically as spindle-shape and the average number of colonies which form in primary culture was 43±11. MSCs were positive for CD44 and CD29 but negative for CD34, CD45 and HLA-DR with a phenotypical identity of 99%.

上述结果表明，通过密度梯度离心方法分离培养的细胞不是骨髓造血干/祖细胞，而是一群形态和表型均一的间充质干细胞，具有独特的增殖和表型特征及较强的分化潜能。

Pb and leaden oxid plumbous acid accumulator in to human body nerve system, digestive system, hematopoiesis system and kidney have certain affection, usually had better not dissect scrap battery.

铅酸蓄电池中的铅和铅的氧化物对人体神经系统、消化系统、造血系统以及肾脏有一定的影响，通常最好不要解剖废弃的电池。

Objective The radiation sensitive gene rad 21 of Schizosaccharomyces pombe is involved in the repair of double-stranded breaks in DNA and is essential for mitotic growth. The hHR21 sp gene is its human homologue.

目的 检测UV和γ辐射对正常人外周血单核细胞的hHR2 1sp基因转录表达水平及hHR2 1sp在范可尼贫血骨髓造血细胞和激活后的外周血单核细胞的转录表达情况，并分析hHR2 1sp基因在FA贫血发病机制中的作用。

We suppose that there is a presently undefined subfraction of stem cell population that exists in a number of tissues beyond embryonic development. We term them postembryonic pluripotent stem cells. They differ from embryonic stem cells in that they gradually lose some differentiation potentials during development and adopt some special phenotypes once within a certain tissue. They can give rise to different kinds of stem cells; therefore, help to maintain balance during development and metabolism. They provide cells not only for the damaged tissues they reside, but also for damaged tissues different from them by migration triggered by proinflammatory cytokines or growth factors.

我们认为在胚胎发育后的多种组织中都存在一类原始干细胞群体，它们和造血干细胞、神经干细胞等多能干细胞不同，后者只能分化为特定胚层的细胞，而这类原始干细胞可分化为不同胚层的组织细胞；另一方面，它们区别于胚胎干细胞，在妊娠期间会逐渐失去部分分化潜能，并且会出现一些特殊表型或者分子标志，我们称其为胚胎后亚全能干细胞，这类干细胞具有下列特性：可分化为不同胚层的细胞，分布于身体的所有组织和器官，具有相同的表型或标志；他们在胚胎期存在于一些或全部的组织和器官中，可分化为不同类型的多能干细胞并在生长发育和新陈代谢中维持这些多能干细胞保持平衡；可以参与机体自我修复和更新，不仅能分化为所在器官的组织特异性细胞，参与器官重塑，也可以在炎症因子或者生长因子的趋化作用下，远处转移修复受损组织。

Prestimulation of HSCs with cytokines almost becomes a routine procedure in HSCs transduction with retroviral vectors.

用细胞因子进行预刺激成为造血干细胞基因转染的常规方案。

Among its many biological activities, the major function of GM-CSF is to stimulate hematogenie stem cells prolification from silent stage to S phage, so that the stem cells can differentiate into granulocyte-macrophage cells.

有4个外显子和3个内含子，基因定位于5号染色体长臂5q21-5q32区，大多数器官均能产生GM-CSF，GM-CSF有多种生物活性，作用于多种细胞谱系，其主要作用是刺激造血祖细胞增殖即从静止期进入S期，并分化为粒细胞---单核巨噬细胞。

The synthetical curative effects of Yang Gan Kang Ai Wan and TACE in moderate or advanced primary liver cancer are better than TACE.Yang Gan Kang Ai Wan has the effects of assistance and suppression on TACE.It could prolongate survival period,improve the survival rate,suppress or abate the damage to hemopoietic system,liver function and hepatic fibrosis caused by TACE.

养肝抗癌丸联合TACE疗法能够有效地抑制或减轻TACE疗法导致的毒副反应，保护和改善中晚期原发性肝癌患者造血功能和肝细胞功能，拮抗TACE导致的肝纤维化损害，延长患者的生存期，提高生存率和生存质量，治疗中晚期原发性肝癌的综合疗效优于TACE疗法。

The transmission electron microscope revealed endoplasmic reticula were dilated, the matrix of mitochondria became pale and the cristae of mitochondria shorter in stromal cells from irradiation mice compared with those of controls.

提示：放射复合伤骨髓基质细胞的细胞周期比例、DNA含量和形态的改变可能是导致放射复合伤造血微环境损伤的重要原因之一。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
