小鼠腹腔巨噬細(xì)胞和雜交瘤細(xì)胞樣品*次在較好的生長(zhǎng)條件下進(jìn)行培養(yǎng)。細(xì)胞生長(zhǎng)在改良的動(dòng)態(tài)細(xì)胞培養(yǎng)系統(tǒng)內(nèi)，該系統(tǒng)包含兩個(gè)細(xì)胞反應(yīng)器，每一個(gè)反應(yīng)器中有培養(yǎng)液儲(chǔ)存系統(tǒng)，換液系統(tǒng)，兩個(gè)細(xì)胞培養(yǎng)室及氣室。氣室中初始?xì)怏w為含8%CO2、25%O2的混合氣體；氣室與培養(yǎng)室之間有一層可以進(jìn)行氣體交換的薄膜相隔。每一反應(yīng)器中有一個(gè)培養(yǎng)室，由滲透泵驅(qū)動(dòng)換液，培養(yǎng)液流速大約為60微升/天，稱(chēng)為流動(dòng)培養(yǎng)室。另一個(gè)非換液室稱(chēng)為靜止培養(yǎng)室。溫控裝置維持培養(yǎng)室內(nèi)溫度約為36±1℃，培養(yǎng)液儲(chǔ)存室溫度約為15±2°C。經(jīng)過(guò)15天的空問(wèn)飛行試驗(yàn)表明我國(guó)自行研制的這一裝置基本適合巨噬細(xì)胞的培養(yǎng)，貼附在微載體上的巨噬細(xì)胞在改良的動(dòng)態(tài)培養(yǎng)系統(tǒng)內(nèi)存活良好。裝置還需要進(jìn)一步改進(jìn)和完善。目前，一個(gè)更高水平和更大容量的細(xì)胞反應(yīng)器正在研制中。原核細(xì)胞（prokaryotic cell）沒(méi)有核膜，遺傳物質(zhì)集中在一個(gè)沒(méi)有明確界限的低電子密度區(qū)。DNA為裸露的環(huán)狀分子，通常沒(méi)有結(jié)合蛋白，環(huán)的直徑約為2.5納米，周長(zhǎng)約幾十納米。沒(méi)有恒定的內(nèi)膜系統(tǒng)，核糖體為70S型，原核細(xì)胞構(gòu)成的生物稱(chēng)為原核生物（prokaryote），均為單細(xì)胞生物，通常稱(chēng)為細(xì)菌（bacterium）。
原核細(xì)胞（ procaryotic/prokaryotic cell ）指沒(méi)有核膜且不進(jìn)行有絲分裂、減數(shù)分裂、無(wú)絲分裂的細(xì)胞。這種細(xì)胞不發(fā)生原生質(zhì)流動(dòng)，觀察不到變形蟲(chóng)樣運(yùn)動(dòng)。鞭毛（flagellum）呈單一的結(jié)構(gòu)。光合作用、氧化磷酸化在細(xì)胞膜進(jìn)行，沒(méi)有葉綠體（chloroplast）、線粒體(mitochondrion）等細(xì)胞器(organelles）的分化，只有核糖體。由這種細(xì)胞構(gòu)成的生物，稱(chēng)為原核生物，它包括所有的細(xì)菌和藍(lán)藻類(lèi)。[2]  即構(gòu)成細(xì)菌和藍(lán)藻等低等生物體的細(xì)胞。它沒(méi)有真正的細(xì)胞核（nucleus），只有原核或擬核，所含的一個(gè)基因帶（或染色體），是環(huán)狀雙股單一順序的脫氧核糖核酸分子（circular DNA），沒(méi)有組蛋白（histone）與之結(jié)合無(wú)核仁（nucleolus），缺乏核膜（nuclear envelope）。外層原生質(zhì)中有70 S核糖體與中間體，缺乏高爾基體（Golgi apparatus）、內(nèi)質(zhì)網(wǎng)（E.R.）、線粒體和中心體（centrosomes）等。轉(zhuǎn)錄和轉(zhuǎn)譯（transcription and translation）同時(shí)進(jìn)行，四周質(zhì)膜內(nèi)含有呼吸酶。無(wú)有絲分裂（mitosis）和減數(shù)分裂（meiosis），脫氧核糖核酸（DNA）復(fù)制后，細(xì)胞隨即分裂為二。

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.
