求翻译：由于细胞间相互的影响对一些如增殖和分化的细胞特征发挥着重要的调控作用 ，为了模拟组织之间的相互作用，从而建立了共培养体系，通过共培养体系 ,可以在非常接近体内环境下观察细胞与细胞之间的相互作用, 但细胞共培养在技术及应用上仍存在以下问题（1） 与体内环境具有差别 ,并不能完全反映体内的变化;（2） 共培养体系的条件存在一些问题 ,如培养液pH值、细胞培养时间和种植密度等仍需要长期摸索; （3） 组织器官里含有多种细胞 ,如果观察两 - 两细胞之间的相互作用 ,将花费大量的时间、精力和费用因此 ,逐步完善细胞共培养技术 ,将是科技工作者的一项重要任务是什么意思？

Due to cell between mutual of effect on some as proliferation and differentiation of cell features played with important of regulation role, to simulation organization Zhijian of mutual role, to established has total training system, through total training system, can in very close to body environme

Because the mutual influence gives play to the role of important adjustment in some such as hyperplasia and cell characteristic of splitting up among cells, the interaction while organizing for the simulation, thus has established the system of training together, through training the system together
