Qhov sib txawv tseem ceeb ntawm cov hlwb tshwj xeeb thiab cov qia hlwb yog cov hlwb tshwj xeeb yog cov hlwb sib txawv uas muaj cov haujlwm tshwj xeeb los ua haujlwm thaum cov qia hlwb tsis txawv txav uas tsis yog tshwj xeeb rau kev ua haujlwm tshwj xeeb tab sis muaj peev xwm sib txawv. rau hauv cov hlwb tshwj xeeb.

Multicellular complex kab mob tsim los ntawm lub qe fertilized los yog ib tug zygote, uas yog ib tug tib diploid cell. Lub zygote muaj peev xwm faib thiab tsim cov hlwb. Yog li ntawd, zygote yog lub hauv paus ntawm kev sib txawv ntawm tes. Nws muaj cov qia hlwb uas yog cov hlwb tsis txawv. Stem cells tuaj yeem faib tau yam tsis muaj kev txwv. Undifferentiated cells dhau los ua cov hlwb tshwj xeeb lossis cov hlwb sib txawv raws li kev sib txawv. Stem cells muab nce rau cov hlwb tshwj xeeb. Cov hlwb tshwj xeeb muaj cov qauv tshwj xeeb ntawm cov ntaub so ntswg thiab ib txoj haujlwm tshwj xeeb los ua.

Cov Cell Tshwj Xeeb yog dab tsi?

Cellular sib txawv yog txheej txheem uas hloov cov hlwb tshwj xeeb tshaj plaws rau hauv lub xeev ntawm ntau hom cell tshwj xeeb. Hauv kev loj hlob biology, cellular sib txawv yog ib qho tseem ceeb. Raws li qhov tshwm sim ntawm kev sib txawv, cov ntaub so ntswg sib txawv hauv lub cev muaj ntau hom kab mob tshwj xeeb. Cov hlwb tshwj xeeb muaj cov ntaub so ntswg tshwj xeeb; yog li lawv ua haujlwm tshwj xeeb. Piv txwv li, cov qe ntshav liab yog cov hlwb tshwj xeeb hauv cov ntaub so ntswg. Lawv nqa oxygen mus rau lwm cov ntaub so ntswg ntawm lub cev.

Daim duab 01: Cov Cells Tshwj Xeeb

Tsis zoo li cov qia hlwb, cov hlwb tshwj xeeb muaj kev ua haujlwm zoo hauv lub cev. Kev sib txuas ntawm cov qia hlwb thiab cov hlwb tshwj xeeb yog cov hlwb tshwj xeeb yog tsim los ntawm kev faib cov qia hlwb rau hauv cov menyuam ntxhais sib txawv. Thaum sib txawv ntawm cov qia hlwb, qhov loj thiab cov duab hloov pauv. Tsis tas li ntawd, kev sib txawv ntawm tes ua rau muaj kev hloov pauv hauv kev ua haujlwm hauv metabolic thiab cov lus teb rau stimuli. Txawm li cas los xij, kev sib txawv ntawm tes tsis ua rau muaj kev hloov pauv hauv DNA ib ntus. Tab sis, nws yog ib qho tseem ceeb uas yuav tsum tau hais tias kev sib txawv ntawm tes muaj peev xwm hloov tau qee cov noob uas tsis tsim nyog rau cov ntaub so ntswg. Cov paj hlwb, cov leeg hlwb, cov hlwb epithelial, cov qe ntshav yog qee qhov piv txwv rau cov hlwb tshwj xeeb.

Stem Cells yog dab tsi?

qia hlwb yog cov hlwb tsis txawv txav uas tsis yog tshwj xeeb rau kev ua haujlwm tshwj xeeb. Cov hlwb no muaj peev xwm sib txawv rau hauv cov hlwb tshwj xeeb thiab tseem tuaj yeem ua rau ntau cov qia hlwb los ntawm mitosis. Muaj ob lub cim tshwj xeeb ntawm cov qia hlwb uas pab kom paub qhov txawv ntawm lwm cov hlwb. Ua ntej, lawv yog cov hlwb tsis tshwj xeeb uas tuaj yeem rov ua dua lawv tus kheej ntawm kev faib cell txawm tias tom qab qee lub sijhawm tsis ua haujlwm. Piv txwv li, nyob rau hauv lub cev xws li cov pob txha pob txha, muaj kev faib cov qia hlwb kom kho thiab hloov cov ntaub so ntswg puas. Qhov thib ob, lawv muaj peev xwm tsim tau rau hauv cov ntaub so ntswg lossis cov kab mob hauv lub cev.

Cov qia hlwb muaj ntau qhov sib txawv. Lawv tuaj yeem raug categorized li totipotent, pluripotent thiab multipotent. Totipotent qia hlwb muaj peev xwm sib txawv rau hauv embryonic cell hom. Pluripotent qia hlwb yog tsim los ntawm cov hlwb totipotent thiab muaj peev xwm sib txawv rau yuav luag txhua hom cell, thiab lawv tau muab los ntawm peb txheej kab mob. Multipotent qia hlwb muaj peev xwm sib txawv rau ntau lub hlwb uas yog tib tsev neeg.

Daim duab 02: Stem Cells

Ob hom qia hlwb siv rau kev tshawb fawb tam sim no, thiab lawv yog embryonic qia hlwb thiab cov neeg laus / somatic qia hlwb (cov qog nqaij hlav tshwj xeeb). Embryonic qia hlwb yog cov hlwb uas muaj nyob rau hauv lub blastocyst thiab nyob rau hauv lub embryo ntawm 3 mus rau 5 hnub tom qab fertilization. Lawv yog cov pluripotent; Yog li ntawd, tag nrho cov derivatives ntawm peb txheej kab mob yog tsim los ntawm embryonic qia hlwb. Cov neeg laus los yog somatic qia hlwb yog cov qia hlwb uas kho thiab tswj cov ntaub so ntswg puas. Feem ntau cov neeg laus qia hlwb muaj ntau lub zog thaum pluripotent qia hlwb tsis tshua pom. Pob txha pob txha yog ib qho piv txwv rau cov neeg laus qia hlwb uas siv rau ntau yam kev kho mob.

Dab tsi yog qhov zoo sib xws ntawm Cov Txheej Txheem Tshwj Xeeb thiab Cov Kab Cell?

  • Stem cells muaj peev xwm sib txawv rau hauv cov hlwb tshwj xeeb.
  • Stem cells yog lub hauv paus rau cov hlwb tshwj xeeb uas muaj nyob hauv cov ntaub so ntswg thiab kabmob.
  • Cov qia hlwb thiab cov hlwb tshwj xeeb muaj nyob rau hauv ntau lub cellular complex kab mob.
  • Lawv yog eukaryotic hlwb.

Dab tsi yog qhov txawv ntawm Cov Kab Mob Tshwj Xeeb thiab Kab Mob?

Cov hlwb tshwj xeeb yog cov hlwb sib txawv thiab muaj cov haujlwm tshwj xeeb los ua thaum cov qia hlwb tsis txawv thiab cov hlwb tsis tshwj xeeb uas tuaj yeem faib tau yam tsis muaj kev txwv. Yog li qhov no yog qhov sib txawv tseem ceeb ntawm cov hlwb tshwj xeeb thiab cov qia hlwb. Ntxiv mus, cov hlwb tshwj xeeb muaj cov qauv tshwj xeeb ntawm cov ntaub so ntswg, thiab lawv raug xa mus ua cov haujlwm tshwj xeeb thaum cov qia hlwb tsis ua haujlwm tshwj xeeb.

Tsis tas li ntawd, cov qia hlwb tsis muaj cov duab thiab qhov loj me, thaum cov hlwb tshwj xeeb muaj cov duab tshwj xeeb thiab loj. Li no, nws yog lwm qhov sib txawv ntawm cov hlwb tshwj xeeb thiab cov qia hlwb.

Cov hauv qab no infographic tabulates ib sab ntawm qhov sib txawv ntawm cov hlwb tshwj xeeb thiab qia hlwb.

Summary – Specialized Cells vs Stem Cells

qia hlwb yog cov hlwb tsis sib xws uas muaj peev xwm faib tau rau lub sijhawm ntev thiab ua rau cov hlwb tshwj xeeb. Stem cells yog cov hlwb tsis tshwj xeeb uas tsis muaj ib txoj haujlwm tshwj xeeb los ua. Tsis zoo li ntawd, cov hlwb tshwj xeeb muaj cov haujlwm tshwj xeeb los ua. Lawv yog cov hlwb sib txawv. Lawv muaj npe raws li cov leeg nqaij, cov hlwb ntawm daim tawv nqaij thiab cov hlab ntsha, thiab lwm yam raws li cov ntaub so ntswg. Yog li, qhov no qhia txog qhov sib txawv ntawm cov hlwb tshwj xeeb thiab cov qia hlwb.
