小鼠腹腔巨噬细胞和杂交瘤细胞样品*次在较好的生长条件下进行培养。细胞生长在改良的动态细胞培养系统内，该系统包含两个细胞反应器，每一个反应器中有培养液储存系统，换液系统，两个细胞培养室及气室。气室中初始气体为含8%CO2、25%O2的混合气体；气室与培养室之间有一层可以进行气体交换的薄膜相隔。每一反应器中有一个培养室，由渗透泵驱动换液，培养液流速大约为60微升/天，称为流动培养室。另一个非换液室称为静止培养室。温控装置维持培养室内温度约为36±1℃，培养液储存室温度约为15±2°C。经过15天的空问飞行试验表明我国自行研制的这一装置基本适合巨噬细胞的培养，贴附在微载体上的巨噬细胞在改良的动态培养系统内存活良好。装置还需要进一步改进和完善。目前，一个更高水平和更大容量的细胞反应器正在研制中。原核细胞（prokaryotic cell）没有核膜，遗传物质集中在一个没有明确界限的低电子密度区。DNA为裸露的环状分子，通常没有结合蛋白，环的直径约为2.5纳米，周长约几十纳米。没有恒定的内膜系统，核糖体为70S型，原核细胞构成的生物称为原核生物（prokaryote），均为单细胞生物，通常称为细菌（bacterium）。
原核细胞（ procaryotic/prokaryotic cell ）指没有核膜且不进行有丝分裂、减数分裂、无丝分裂的细胞。这种细胞不发生原生质流动，观察不到变形虫样运动。鞭毛（flagellum）呈单一的结构。光合作用、氧化磷酸化在细胞膜进行，没有叶绿体（chloroplast）、线粒体(mitochondrion）等细胞器(organelles）的分化，只有核糖体。由这种细胞构成的生物，称为原核生物，它包括所有的细菌和蓝藻类。[2]  即构成细菌和蓝藻等低等生物体的细胞。它没有真正的细胞核（nucleus），只有原核或拟核，所含的一个基因带（或染色体），是环状双股单一顺序的脱氧核糖核酸分子（circular DNA），没有组蛋白（histone）与之结合无核仁（nucleolus），缺乏核膜（nuclear envelope）。外层原生质中有70 S核糖体与中间体，缺乏高尔基体（Golgi apparatus）、内质网（E.R.）、线粒体和中心体（centrosomes）等。转录和转译（transcription and translation）同时进行，四周质膜内含有呼吸酶。无有丝分裂（mitosis）和减数分裂（meiosis），脱氧核糖核酸（DNA）复制后，细胞随即分裂为二。

Mouse peritoneal macrophages and hybridoma samples were cultured for the first time under better growth conditions. The cells were grown in a modified dynamic cell culture system that contained two cell reactors, each containing a culture fluid storage system, a fluid exchange system, two cell culture chambers, and a gas chamber. The initial gas in the gas chamber is a mixed gas containing 8% CO2 and 25% O2. The gas chamber is separated from the culture chamber by a layer of gas exchangeable membrane. Each reactor has a culture chamber, driven by the osmotic pump fluid exchange, the culture fluid flow rate of about 60 l / day, called the flow chamber. Another non-fluid change chamber is called a stationary culture chamber. Temperature control device to maintain the indoor temperature is about 36 ± 1 ℃, the temperature of the storage compartment is about 15 ± 2 ° C. After 15 days of flight tests showed that this device developed by our country is basically suitable for macrophage culture, macrophages attached to the microcarriers in the improved dynamic culture system, living well. The device still needs to be further improved and improved. Currently, a higher level and larger capacity of the cell reactor is under development. Prokaryotic cells have no nuclear membrane and their genetic material is concentrated in a region of low electron density that is not clearly defined. DNA is a naked, circular molecule that usually has no bound protein. The diameter of the ring is about 2.5 nanometers and the circumference is about tens of nanometers. There is no constant intima system, the ribosome is type 70S, and prokaryotic cells are called prokaryotes, all of which are unicellular organisms, often referred to as bacterium.
Procaryotic / prokaryotic cells are cells that do not have a nuclear membrane and do not undergo mitosis, meiosis, and mitosis. Protoplast flow did not occur in such cells and no amoeboid-like movement was observed. Flagellum is a single structure. Photosynthesis, oxidative phosphorylation, occurs on the cell membrane without the differentiation of chloroplasts, organelles such as mitochondria, and only ribosomes. Organisms formed by such cells, called prokaryotes, include all bacteria and cyanobacteria. [2] Cells that make up lower organisms such as bacteria and cyanobacteria. It has no real nucleus, only a prokaryotic or pseudonuclear, contains a gene zone (or chromosome) is a circular double-stranded single sequence of circular DNA, there is no histone (histone) and The combination of nucleolus, lacking the nuclear envelope. Outer protoplasts have 70 S ribosomes and intermediates, lack of Golgi apparatus, endoplasmic reticulum (E.R.), mitochondria and centrosomes. Transcription and translation (transcription and translation) at the same time, around the plasma membrane contains respiratory enzymes. Without mitosis and meiosis, the cells split into two immediay after DNA replication.
