Hujayralarni etishtirish juda jiddiy vazifadir. Hujayralar uchun yaxshi o'sish muhitini yaratishdan tashqari, u madaniyat jarayonida turli favqulodda vaziyatlarni ham tezda hal qilishi kerak. hujayra kulturalari dagi hujayra to'planishi tez-tez uchraydigan hodisadir. Bu holatning sababi nimada?
Hujayra kulturalaridagi hujayralarning to'planish hodisasini odatda quyidagi jihatlardan tahlil qilish mumkin:
1. Ovqat hazm qilish jarayoni juda qo'pol bo'lishi mumkin, pipetkalar juda qattiq bo'lishi mumkin, juda uzoq vaqt davomida hazm qilish, juda kuchli yoki zaharli ovqat hazm qilish sharbati va boshqalar hujayra o'limiga olib keladi. Hujayra o'lganidan keyin u DNKni chiqaradi, boshqa hujayralarni o'rab oladi va yopishqoq hujayralar klasterini hosil qiladi.
2. Haddan tashqari hujayra sentrifugalash tezligi yoki juda uzoq vaqt ham hujayra to'planishiga osonlikcha olib kelishi mumkin.
3. Ovqat hazm qilish tugallanmagan bo'lsa, hujayralar va hujayra o'rtasidagi aloqa ajratilmaydi; ovqat hazm qilish tugagach, dumaloq hujayralar to'planib qolishga moyil bo'lib, yana ajralish qiyin bo'ladi.
4. Noto'g'ri holatda va qarigan hujayralar ham to'p bo'lib o'sishi mumkin (masalan, muhitni o'zgartirishning kechikishi, o'ta uzoq vaqt o'tishi, ifloslanish va h.k. tufayli yomon hujayra holati).
5. O'tish paytida bir tekisda pipetlash bo'lmaydi, shuningdek ko'plab hujayralar bo'laklari mavjud bo'lib, ular ekilganida to'p bo'ladi.
6. Noto'g'ri emlash yoki hazm bo'lmagan hujayralar.
7. Tebranishsiz madaniyat yoki juda ko'p bakteriyalar (hujayralar) to'planish hosil qiladi.
Agar hujayra kulturalari ichidagi hujayralar to'planib qolgandek ko'rinsa, sababini bilish uchun yuqoridagi jihatlarni tahlil qilishingiz va oldini olish uchun operatsiyadan oldin qat'iy tartiblarni shakllantirishingiz mumkin. bu hodisa.
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.
