Keng miqyosli hujayra madaniyati texnologiyasi atrof-muhit sharoitlarini sun'iy nazorat qilish va foydali mikroorganizmlarni, hayvon va o'simlik hujayralarini yuqori zichlikdagi keng miqyosda etishtirish texnologiyasini anglatadi. Bu gen rekombinatsiyasi, hujayra sintezi va oziq-ovqat va tibbiyot kabi sanoat ishlab chiqarishidagi boshqa texnologiyalar orqali olingan ko'plab yangi hujayralar uchun asosdir. Hujayra fabrikalari keng ko'lamli hujayra madaniyatida ishlatiladigan sarf materiallari.
Hujayra fabrikalarining umumiy qatlamlari 1 qatlam, 2 qatlam, 5 qatlam, 10 qatlam, 40 qatlam va boshqalarni o'z ichiga oladi, ular asosan yopishgan hujayralar madaniyati uchun mos. O'quv ko'lamini kengaytirish uchun qatlamlar sonini ko'paytirish orqali erishish mumkin. Ushbu o'qitish usuli katta maydondan maksimal darajada foydalanish, zavod maydonini tejash, ishchi kuchi va moddiy resurslarni tejash imkonini beradi.
Sanoatda hujayra zavodlari vaktsinalar, monoklonal antikorlar yoki farmatsevtika sanoatida ommaviy ishlab chiqarishda keng qo'llaniladi. Keng miqyosda ekilgan hayvonlarning umumiy hujayralari orasida tovuq embrioni fibroblastlari, birlamchi hamster buyrak hujayralari va boshqa birlamchi hujayralar, shuningdek, inson diploid hujayralari, CHO hujayralari va Vero hujayralari mavjud. Ushbu hujayralar vaktsina ishlab chiqarishda, monoklonal antikor tayyorlashda, eritropoetin va boshqa mahsulot sohalarida keng qo'llaniladi.
Bundan tashqari, hujayra zavodlari orqali keng ko'lamli hujayra madaniyati hujayra madaniyati qurilmalari sonini kamaytirishi va hujayraning ifloslanish xavfini kamaytirishi mumkin. Bu samarali hujayra madaniyati bo'lib, ko'plab ilmiy tadqiqot muassasalari va farmatsevtika kompaniyalari tomonidan ma'qullanadi.
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.
