The two gangliosides might, in vivo, concertedly modulate the activity of SR 〓-ATPase, and contribute to maintaining the calcium homeostasis of muscle cells.

共存于肌质网膜上的GM1和GM3可能共同参与肌质网膜上钙泵结构和功能的调节，二者相互拮抗作用，维持肌细胞内〓的平衡。

RESULTS In contrast with the control, more cells of the experimental group entered S phase during the early differentiation (24 h, 48 h), whereas a smaller number of cells entered during the late differentiation (72 h) when multinucleated myotubes began to form.

结果 发现肌细胞分化早期即24， 48 h时，与对照组比有更多的细胞进入S期；分化后期即72 h多核肌管形成时，S期比对照组明显减少，而G0/G1期明显高出对照。

Despite of its important role during embryogenesis and reproductive development,more and more studies implied a critical role for Rhox5 on the determination and differentiation during myogenesis.

除在生殖系统的发育、精子的形成和成熟过程中发挥重要的作用外，多项研究表明其在肌细胞的发生和分化中担任重要角色，有可能作为MyoD基因的上游调控子或者和其他转录因子协同作用，调控肌细胞的早期发生和分化事件。

These data indicated that Smad3 protein did not play a vital role during the inhibition of myogenic differentiation by hypoxia.

结果提示，Smad3蛋白在低氧抑制成肌细胞分化过程中不起关键的作用，Smad3蛋白水平的降低可能是低氧抑制成肌细胞体外分化过程中的一个伴随事件。

In addition, down-regulation of Smad3 protein might be a concomitant event during the inhibition of myogenic differentiation by hypoxia.

随后我们研究低氧抑制成肌细胞体外分化过程中Smad3蛋白水平降低的原因时发现，Smad3的活性形式磷酸化Smad3蛋白的表达水平在低氧抑制成肌细胞体外分化的过程中下调，与Smad3蛋白水平的降低趋势相平行。

BACKGROUND: Bone marrow mesenchymal stem cells can differentiate into osteoblasts, chondrocyte, sarcoblasts, adipocyte, neuroepithelial cells, as well as vascular endothelial cells under different conditions.

背景：骨髓间充质干细胞在不同条件下可以分别分化为成骨细胞、软骨细胞、成肌细胞、脂肪细胞、神经胶质细胞、血管内皮细胞等。

Mitochondria cristae and membrane in a great measure were anastomosis or vacuolization.Conclusion: All these results suggest that effects of H2S on papillary muscles are due to an increase in potassium efflux through opening the KATP channels at the early phase of ischemia, and acceleration in potassium reuptake through improving the Na+-K+-ATPase at the late phase of ischemia. Endogenous H2S may act as important regulator in electrophysiological characters in ischemic papillary muscles.

外源性H2S前处理可能通过兴奋KATP通道促进缺血早期K+外流，并且由于对Na+-K+-ATP酶的保护作用改善了缺血晚期对K+的重摄取，进而影响缺血环境下豚鼠乳头状肌细胞的电生理效应；乳头状肌细胞内源性产生的H2S可能在心肌缺血损伤时发挥着重要的电生理作用。

As a result, muscle cells may be replaced by fibro-connective tissue.Key words Mascles; denervation; Atrophy; Microscopy

长时间失神经后，最终可能使肌卫星细胞或其它成肌细胞不断消耗，使肌肉恢复功能差。

Muscle satellite cells isolated from skeletal muscle and cultured in vitro are called myoblasts.

从骨骼肌中分离获得的肌卫星细胞在体外培养时被统称为成肌细胞。

Objective To investigate the biological characteristics of superparamagnetic iron oxideslabeled myoblasts in vitro.

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
