Hujayra fabrikasimadaniyat texnologiyasi monoklonal antikor va vaktsina tayyorlash sohalarida muhim rol o'ynaydi. Hujayralarni o'stirishda unga turli omillar ta'sir ko'rsatadi, ular orasida hujayra emlash zichligi hujayra madaniyati jarayoniga ham ta'sir qiladi.
Kumjayra zavodlaridan keng ko'lamli hujayra madaniyati uchun foydalanilganda, hujayra emlashlar soni. hujayralar o'sishiga bevosita ta'sir qiladi. Tegishli inokulyatsiya zichligi hujayra proliferatsiyasini yaxshilashga yordam beradi. Juda yuqori yoki juda past emlash zichligi hujayra o'sishi va ko'payishiga yordam bermaydi. Tegishli emlash konsentratsiyasini qanday tanlashni hujayra metabolizmi, o'sish va ko'payish tezligi va ish ehtiyojlariga qarab aniqlash kerak.
Umuman olganda, kuchli metabolizm va tez o'sadigan hujayralar (masalan, o'simta hujayralari) past konsentratsiya; normal to'qimalar hujayralari asta-sekin o'sib boradi va ularning metabolizmi etarlicha kuchli bo'lmasa, emlash konsentratsiyasi yuqori bo'lishi mumkin; Favqulodda foydalanish uchun emlash pastroq bo'lishi mumkin; ba'zan hujayra morfologiyasini kuzatishni osonlashtirish uchun emlash konsentratsiyasini ham tegishli ravishda kamaytirish mumkin. Oddiy hujayralar hujayra zavodining birlik maydoniga to'g'ri keladigan hujayralar soniga ko'ra urug'lanishi mumkin, ishlatiladigan hujayra zavodi madaniyati maydoniga ko'paytiriladi va keyin ekilgan hujayralarning urug'lik nisbatiga bo'linadi. Hujayralarning juda yuqori yoki juda past emlash miqdori hujayra ko'payishiga yordam bermaydi. Tegishli hujayra emlash miqdori hujayralarning normal o'sishini ta'minlash uchun asosdir.
Hujayra urug'ining zichligi hujayra zavodining madaniyatli hujayralariga ta'sir qiluvchi muhim omil hisoblanadi. Faqatgina tegishli zichlikni nazorat qilish orqali hujayra madaniyati tajribasi muammosiz amalga oshirilishi mumkin.
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.
