Tib neeg kuj nug, dab tsi tuaj yeem txwv qhov loj ntawm lub xov tooj ntawm tes?

Cov xwm txheej txwv qhov loj ntawm hlwb suav nrog: thaj tsam ntawm thaj tsam rau qhov ntim qhov piv (qhov chaw saum npoo / ntim) Nucleo-cytoplasmic ratio. Fragility ntawm cell daim nyias nyias. Yog vim li cas cell tau loj hlob mus rau ib qho txwv yog nws qhov chaw saum npoo rau ntim piv.

Ib yam li ntawd, vim li cas cov hlwb muaj qhov tsawg kawg nkaus? Lub ntsiab lus tseem ceeb yog tias thaj chaw saum npoo rau qhov ntim piv tau me dua li qhov cell tau loj dua. Yog li ntawd, yog hais tias tus cell loj hlob dhau ib qho kev txwv, cov khoom siv tsis txaus yuav tuaj yeem hla cov membrane sai txaus kom haum rau qhov nce cellular ntim.

Hais txog qhov no, dab tsi yam txwv qhov tsawg kawg nkaus thiab siab tshaj plaws ntawm cov cell?

Cov xwm txheej txwv qhov loj ntawm cov cell muaj xws li:
