Qhov sib txawv tseem ceeb ntawm cov neeg laus thiab cov embryonic qia hlwb yog cov neeg laus qia hlwb muaj ntau lub zog thaum lub embryonic qia hlwb yog pluripotent.

Stem cells yog ib pawg ntawm cov hlwb uas muaj peev xwm los faib thiab loj hlob mus rau ntau hom hlwb hauv lub cev. Lawv txawv ntawm cov hlwb ib txwm vim lawv faib thiab rov ua dua lawv tus kheej nyob rau lub sijhawm ntev dua. Tsis tas li ntawd, lawv yog cov cell tsis tshwj xeeb uas tsis muaj cov cellular ua haujlwm hauv lub cev. Lawv muaj peev xwm sib txawv thiab dhau los ua cov hlwb tshwj xeeb hauv lub cev xws li cov hlwb hlwb, cov qe ntshav, thiab cov leeg nqaij. Cov neeg laus qia hlwb thiab embryonic qia hlwb yog ob hom qia hlwb.

Tus Neeg Laus Stem Cells yog dab tsi?

Cov neeg laus qia hlwb muaj nyob rau hauv cov ntaub so ntswg sib txawv ntawm lub cev. Cov ntaub so ntswg muaj xws li cov leeg pob txha, daim siab, pancreas, hlwb, qhov muag, cov ntaub so ntswg, daim tawv nqaij, pob txha pob txha, ntshav thiab hauv ob sab phlu ntawm txoj hnyuv. Ntxiv mus, cov neeg laus qia hlwb tseem nyob hauv cov ntaub so ntswg tsis txawv, nrog kev txuas ntxiv nws tus kheej thiab tsim cov ntawv luam zoo tib yam ntawm cov hlwb thoob plaws lub neej ntawm lub cev. Lawv tau txais kev sib txawv rau hauv cov hlwb tshwj xeeb ntawm lawv cov ntaub so ntswg ntawm keeb kwm thaum xav tau.

Daim duab 01: Cov Neeg Laus Stem Cells Kho

Hematopoietic stem cells yog ib hom kab mob laus laus uas muaj nyob hauv cov pob txha. Lawv suav hais tias yog cov qia hlwb uas muaj zog ntau vim lawv ua rau ntau hom qe ntshav los ntawm ib hom hlwb. Kev cai gene qhia yog lub luag haujlwm rau cov kev hloov pauv hauv cov hlwb sib txawv. Nws yog tswj los ntawm tshwj xeeb hom ntawm cov ntaub ntawv transcription. Tsis tas li ntawd, cov qia hlwb uas muaj nyob rau hauv lub hlwb yog multipotent. Lawv ua rau cov leeg nqaij thiab cov ntshav.

Dab tsi yog embryonic Stem Cells?

Cov qia hlwb yog cov hlwb uas tsis muaj qhov sib txawv uas muaj nyob rau hauv lub cell loj ntawm lub blastocyst - lub pob hollow ntawm cov hlwb tsim los ntawm zygote tom qab mitosis sai. Yog li ntawd, cov qia hlwb no tau muab faib ua cov qia hlwb tam sim no nyob rau theem pib ntawm kev loj hlob ntawm embryonic.

Embryonic qia hlwb yog pluripotent. Yog li ntawd, lawv ua rau cov hlwb ntawm peb txheej kab mob - endoderm, ectoderm, thiab mesoderm - tsuas yog cov placenta thiab umbilical qaum. Pluripotency distinguishes embryonic qia hlwb los ntawm cov laus qia hlwb.

Daim duab 02: Cov Kabmob Embryonic

Cov kab mob embryonic muab kev pabcuam tseem ceeb raws li cov peev txheej txuas ntxiv hauv kev kawm txog cov kab mob thiab rau kev sim tshuaj kho thiab tshuaj. Raws li cov xwm txheej tau hais tseg, embryonic stem cells muaj peev xwm los faib ua ntu zus.

Dab tsi yog qhov zoo sib xws ntawm cov neeg laus thiab cov kab mob embryonic?

  • Cov neeg laus thiab cov embryonic qia hlwb yog ob hom qia hlwb hauv ntau cov kab mob.
  • Ob lub qia hlwb muaj peev xwm ua kom sib npaug thiab sib txawv.
  • Tsis tas li, ob lub embryonic thiab cov neeg laus qia hlwb ua haujlwm kho lub cev.

Dab tsi yog qhov txawv ntawm Cov Neeg Laus thiab Embryonic Stem Cells?

Cov neeg laus qia hlwb thiab embryonic qia hlwb yog ob hom qia hlwb. Qhov sib txawv tseem ceeb ntawm cov neeg laus thiab cov embryonic qia hlwb yog cov neeg laus cov hlwb muaj ntau lub zog vim lawv muaj peev xwm sib txawv thaum lub embryonic qia hlwb yog pluripotent vim lawv muaj peev xwm sib txawv rau txhua hom cell. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm cov neeg laus thiab cov embryonic qia hlwb yog tias embryonic qia hlwb tuaj yeem loj hlob hauv cov kab lis kev cai ntawm tes thaum kev loj hlob ntawm cov neeg laus qia hlwb hauv cov kab lis kev cai ntawm tes yog qhov nyuaj heev.

Ntxiv mus, qhov sib txawv tseem ceeb ntawm cov neeg laus thiab cov embryonic qia hlwb yog tias cov neeg laus qia hlwb muaj nyob rau hauv cov neeg laus cov ntaub so ntswg thaum lub embryonic qia hlwb muaj nyob rau hauv thaum ntxov txoj kev loj hlob ntawm blastocyst theem.

Summary – Adult vs Embryonic Stem Cells

Qhov sib txawv tseem ceeb ntawm cov neeg laus thiab cov embryonic qia hlwb nyob hauv lawv cov potency. Qhov ntawd yog; Cov neeg laus qia hlwb muaj ntau lub zog thaum embryonic qia hlwb yog pluripotent. Cov neeg laus qia hlwb muaj nyob rau hauv cov ntaub so ntswg sib txawv ntawm lub cev xws li daim siab, pancreas, cov leeg pob txha, thiab lwm yam. Kev tswj cov noob qhia yog lub luag haujlwm rau kev hloov pauv ntawm cov hlwb sib txawv los ntawm cov neeg laus qia hlwb. Ntawm qhov tod tes, embryonic qia hlwb muaj nyob rau hauv lub cell loj ntawm lub blastocyst. Cov qia hlwb no ua rau cov hlwb ntawm ectoderm, endoderm, thiab mesoderm. Tsis tas li ntawd, embryonic qia hlwb faib tsis tu ncua raws li cov xwm txheej tau hais tseg. Nov yog cov ntsiab lus ntawm qhov sib txawv ntawm cov neeg laus thiab cov embryonic qia hlwb.
