Imboni Yeseliiyisiko leseli elinezingqimba eziningi elisebenzisekayo elifanele isiko lamaseli amakhulu. Ngaphezu kwendawo ethile yesiko lamaseli, ujusi wokugaya ukudla nawo uyisixazululo esibalulekile.
Esikweni le-in vitro lamaseli ezicubu kanye nokuhlakazwa kwamaseli ezicubu kusikompilo lamangqamuzana ayinhloko (i-thishu block iyalungiswa ekumisweni kweseli elilodwa) kanye nakwi-subculture, ukugayeka kokudla kanye nokuhlakazwa kwamaseli akhulayo anamathelayo kufanele kusebenzise isisombululo sokugaya kwamangqamuzana ezicubu. Isixazululo sokugaya esisetshenziswa kubuchwepheshe bosiko lwefekthri yamaseli ngokuyinhloko i-trypsin, EDTA, njll.
Izingxenye eziyinhloko zolwelwesi lwamangqamuzana nokunamathela phakathi kwamaseli ama-lipoprotein nama-polysaccharides. I-trypsin ku-trypsin ingaguqula amaprotheni abe ama-peptones, futhi i-pancreatic lipase ingabola amafutha abe i-glycerol nama-fatty acids, ngaleyo ndlela ihlukanise amangqamuzana. Amaseli ahlanjululwa. Umsebenzi wesisombululo sokugaya ngokuyinhloko uwukukhipha i-hydrolyze amaprotheni e-intercellular (njenge-extracellular matrix), ukuhlakaza izicubu noma amangqamuzana anamathelayo abe yingqamuzana eyodwa, nokwenza ukumiswa kweseli ukuze kwenziwe olunye ucwaningo.
Ama-enzyme okugaya adlala indima ebalulekile. esikweni lamafekthri amaseli, kodwa kufanele kuqashelwe ukuthi amaseli ahlukene anezimpendulo ezihlukene kuma-enzyme e-pancreatic. Lapho inani le-pH lingu-8.0 nezinga lokushisa lingu-37 °C, isisombululo se-enzyme ye-pancreatic sinomphumela onamandla kakhulu. , ukugxila, izinga lokushisa kanye nesikhathi kufanele kulawulwe kahle uma usebenzisa, ukuze ugweme ukugaya ngokweqile okuthinta ukunamathela nokukhula kwamaseli.
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.
