Txheej txheem thiab cov kauj ruam ntawm Cell txawv

A cell muaj peev xwm ntawm sib txawv rau hauv tej yam cell lub npe hu ua "totipotent". Piv txwv ntawm qia thiab progenitor hlwb muaj xws li: Hematopoietic Stem Cells - Cov no yog los ntawm cov pob txha pob txha thiab koom nrog hauv kev tsim cov ntshav liab thiab dawb hlwb zoo li cov platelets.

Ib qho ntxiv, kev sib txawv ntawm tes yog dab tsi muab ib qho piv txwv?

Cell txawv Txheej txheem Piv txwv li, pancreas lossis thyroid yuav tso tawm cov tshuaj hormone hu rau kev loj hlob ntawm tes. Qhov kev hloov pauv no ncaj qha cuam tshuam rau cov proteins uas sau DNA, tig nws mus rau hauv cov protein ua haujlwm thiab ntau lub hlwb.

Kuj Paub, 3 yam piv txwv ntawm cov tsiaj sib txawv yog dab tsi? Lub palisade cell thiab hauv paus plaub hau cell yog ob piv txwv ntawm cov hlwb sib txawv hauv cov nroj tsuag. Cov phev cell ,ov ov cell , ciliated epithelial cell , thiab nerv hlwb yog piv txwv ntawm cov hlwb sib txawv hauv tsiaj txhu . Cov phev cell yog ib piv txwv ntawm ib tug tshwj xeeb cell.

Tsis tas li ntawd, kev sib txawv ntawm tes yog dab tsi?

Cellular sib txawv yog tus txheej txheem uas ib tug tsawg tshwj xeeb cell ua ib tug tshwj xeeb cell hom. Kev sib txawv tshwm sim ntau zaus thaum lub sij hawm kev loj hlob ntawm ib tug multicellular kab mob. Lub cev hloov los ntawm ib tug zygote mus rau ib tug complex system ntawm cov ntaub so ntswg thiab cell hom.

Vim li cas cell sib txawv tseem ceeb?

Cov hlwb sib txawv yog tseem ceeb nyob rau hauv ib tug multicellular kab mob vim hais tias lawv muaj peev xwm ua ib tug tshwj xeeb muaj nuj nqi nyob rau hauv lub cev. Txawm li cas los xij, kev tshwj xeeb los ntawm tus nqi. Tus nqi yog qhov cov hlwb sib txawv feem ntau poob lub peev xwm los ua cov ntawv luam tshiab ntawm lawv tus kheej.
