Cells sib txawv los tsim ntau hom cell. Cov kab mob tsiaj sib txawv thaum ntxov, qhov ntau lub hlwb tuaj yeem sib txawv thoob plaws lub neej.
Pob noob qes dhau los ntawm kev sib txawv?
Cell Differentiation and Development
Cell differentiation is tsuas yog ib feem ntawm daim duab loj ntawm cog kev loj hlob. Raws li cov kab mob hauv nruab nrog cev txhim kho (tus txheej txheem ntawm organogenesis), lub precursors ntawm cov ntaub so ntswg systems tsim nyob rau hauv teb rau positional signals.
Cov hlwb puas sib txawv?
Dedifferentiation yog txheej txheem uas cov hlwb tsim rov qab, los ntawm qhov sib txawv ntau dua mus rau lub xeev tsis sib txawv. Qhov tshwm sim tuaj yeem pom ntawm qib ntawm noob, protein, morphology, thiab kev ua haujlwm. … Cov kev hloov ntawm plaub theem tshwm sim thaum lub sij hawm dedifferentiation.
piv txwv ntawm kev sib txawv ntawm tes yog dab tsi?
Nws yog txheej txheem uas lub cell hloov mus rau lwm hom cell. … Ib qho piv txwv ntawm kev sib txawv ntawm tes yog kev txhim kho ntawm ib leeg-celled zygote rau hauv ntau lub embryo uas txuas ntxiv txhim kho mus rau ntau txoj hauv kev sib txawv ntawm cov xov tooj sib txawv ntawm tus menyuam hauv plab.
