Cum cellulas culturae uti cellulae solutiones hypertonicas vel hypotonicas in solutionibus hypertonicis vel hypotonicis possunt statim retrahere vel intumescere et rumpi. Pressio ergo osmotica una est ex condicionibus magni momenti ad cellulas colendas in vitro. Tutatio pressi osmotici mammalium et aliorum textorum animalium in vitro maxime affinis est NaCl, sed relatio pressi osmotici aliorum dielectricorum neglecta esse non potest. Pressio osmotica proportionalis est numero moleculorum et ions soluti per unitatem voluminis solvendi. Quam ob rem magni momenti est stateram ion temperare in media cultura quadam proportione et osmoticam pressionem normalem conservare. Hoc est non solum tensio cellae ponere, sed etiam metabolismum cellularum moderari. Quia extracellular ion onerariis et coniunctis ion mutatur excessus nutrimentorum aliorum (ut amino acida, sucrosa, etc.), directe afficit synthesim systematis cellularum fundamentalum. genus et genus cellularum. Pressio osmotica plasmatis humani est 290 mmol/L, quae specimen osmoticae pressionis aestimatur ad colendas cellulas humanas in vitro. Pressura osmotica cellularum mammalium est fere 290 ad 300 mmol/L. Fibroblasts pulmonis embryonis humani sunt 250-325 mmol/L, et mures circiter 310 mmol/L. In applicationibus practicis, pressio osmotica 260-320 mmol/L pluribus cellulis apta est., varias causas susceptibilis est. Ut temperatura, PH valorem, ambitus gasi etc., quarum pressio osmotica etiam magni ponderis est.
Ad summam, pressio osmotica normalem cellularum incrementum directe afficit. Cum utens officinam cellularum ad cellulas colendas, oportet aptam osmoticam pressionem secundum cellularum condiciones ponere, ut bonum incrementum cellularum curet.
The ideal osmotic pressure of cell factory cultured cells varies with the type and race of cells. The osmotic pressure of human plasma is 290 mmol/L, which is considered to be the ideal osmotic pressure for culturing human cells in vitro. The osmotic pressure of mammalian cells is generally 290 to 300 mmol/L. Human embryonic lung fibroblasts are 250-325 mmol/L, and mice are about 310 mmol/L. In practical applications, the osmotic pressure of 260-320 mmol/L is suitable for most cells.
To sum up, the osmotic pressure directly affects the normal growth of cells. When using the cell factory to cultivate cells, it is necessary to maintain an appropriate osmotic pressure according to the conditions of the cells, so as to ensure the good growth of the cells.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
