Qhov sib txawv tseem ceeb ntawm fetal thiab embryonic stem cells yog cov fetal stem cells muaj kev sib piv ntau dua thaum lub embryonic qia hlwb tsis sib txawv.

Stem cells yog ib hom hlwb uas muaj peev xwm sib txawv rau ntau hom hlwb. Lawv kuj muaj peev xwm rov ua dua tus kheej thiab tsim tib hom qia hlwb hauv qhov ntau dua. Yog li ntawd, stem cells yog lub hauv paus ntawm kev loj hlob ntawm lub cev. Muaj ntau hom qia hlwb. Cov hom loj muaj xws li fetal stem cells, embryonic stem cells, cov ntaub so ntswg tshwj xeeb qia hlwb, mesenchymal qia hlwb thiab induced pluripotent qia hlwb. Fetal thiab embryonic qia hlwb tshwm sim thaum lub sij hawm zygote txoj kev loj hlob thiab lawv thaum kawg tsim mus rau ib tug multicellular kab mob. Tsis tas li ntawd, kev ua haujlwm dav dav ntawm qia hlwb suav nrog kev loj hlob thiab kev sib ntxiv los hloov cov hlwb puas lossis tuag.

Fetal Stem Cells yog dab tsi?

Fetal stem cells yog hom qia cell uas muaj nyob hauv fetus. Cov qia hlwb no txawv ntawm embryonic qia hlwb. Yog li ntawd, cov hlwb no yog categorized li ntau txawv hlwb tshaj embryonic qia hlwb. Fetal stem cells muaj lub peev xwm los faib, proliferate thiab tsim cov hlwb progenitor uas sib txawv rau hauv cov hlwb tshwj xeeb. Yog li ntawd, fetal qia hlwb yog multipotent. Lawv ua haujlwm raws li cov hlwb progenitor ntawm peb txheej kab mob: ectoderm, endoderm, thiab mesoderm. Qhov sib txawv ntawm fetal qia hlwb los ntawm embryonic qia hlwb tshwm sim thaum nruab nrab ntawm cov txheej txheem sib txawv.

Daim duab 01: Fetal stem cells

Fetal stem cells raug cais tawm ntawm cov ntshav hauv fetus, cov pob txha pob txha, thiab cov plab hnyuv siab raum nrog rau lub raum thiab lub siab. Cov qia hlwb no muab cov cuab yeej zoo heev rau kev tshawb nrhiav ntau yam ntawm cell biology. Ntxiv mus, lawv muaj lub peev xwm los ua cov cuab yeej kho mob rau kev hloov pauv ntawm tes thiab ex-vivo noob kho.

Dab tsi yog embryonic Stem Cells?

Cov qia hlwb yog ib hom qia hlwb uas muaj nyob rau hauv cov theem pib ntawm kev loj hlob ntawm embryonic. Thaum lub sij hawm fertilization, ib tug txiv neej thiab ib tug poj niam gamete sib sau ua ib tug diploid zygote. Lub zygote tau txais kev faib tawm sai sai los ua ib lub pob ntawm cov hlwb: lub blastocyst. Lub cell loj ntawm lub blastocyst yog tsim los ntawm embryonic qia hlwb.

Embryonic qia hlwb yog pluripotent. Yog li ntawd, lawv tuaj yeem ua rau muaj ntau hom kab mob tshwj xeeb ntawm cov kab mob multicellular. Embryonic qia hlwb sib txawv rau hauv cov hlwb hauv peb txheej kab mob: ectoderm, endoderm, thiab mesoderm. Yog li, cov hlwb no tseem ceeb thiab muaj txiaj ntsig vim lawv muab cov peev txheej txuas ntxiv mus ntxiv hauv kev tshawb fawb txog kev kho mob, tshuaj xyuas tshuaj, thiab kev loj hlob thiab kab mob.

Daim duab 02: Cov Kabmob Embryonic

Hauv kab lis kev cai ntawm tes, kev loj hlob ntawm embryonic qia hlwb yog ib qho yooj yim. Yog li ntawd, qhov chaw kuaj tau los ntawm embryonic qia hlwb tuaj yeem raug ntxias kom sib txawv rau ntau hom cell tshwj xeeb. Cov no suav nrog lub plawv hlwb, cov hlab ntsha hlwb, cov hlwb tsim cov tshuaj insulin, thiab lwm yam.

Dab tsi zoo sib xws ntawm Fetal thiab Embryonic Stem Cells?

  • Fetal thiab embryonic qia hlwb yog ob hom qia hlwb uas tshwm sim thaum lub sij hawm kev loj hlob ntawm zygote mus rau hauv ib tug multicellular kab mob.
  • Ob hom qia hlwb muaj peev xwm loj hlob, sib faib thiab sib txawv rau ntau hom cell tshwj xeeb.

Qhov txawv ntawm Fetal thiab Embryonic Stem Cells yog dab tsi?

Qhov sib txawv tseem ceeb ntawm fetal thiab embryonic qia hlwb yog lub zog ntawm kev sib txawv. Qhov ntawd yog; Lub fetal qia hlwb yog multipotent thaum embryonic qia hlwb yog pluripotent. Yog li ntawd, fetal stem cells muaj ntau qhov sib txawv dua li embryonic qia hlwb. Tsis tas li ntawd, cov fetal qia hlwb muaj nyob rau hauv fetus thaum lub embryonic qia hlwb muaj nyob rau hauv thaum ntxov theem ntawm embryonic txoj kev loj hlob. Yog li ntawd, peb tuaj yeem xav txog qhov no kuj yog qhov sib txawv ntawm fetal thiab embryonic qia hlwb.

Cov hauv qab no qhia txog qhov sib txawv ntawm fetal thiab embryonic qia hlwb.

Summary – Fetal vs Embryonic Stem Cells

Fetal stem cells muaj ntau lub zog tam sim no hauv fetus. Cov hlwb no txawv dua li cov embryonic qia hlwb. Fetal stem cells tseem ua rau cov hlwb progenitor. Ntawm qhov tod tes, embryonic qia hlwb muaj nyob rau hauv lub puab loj ntawm lub blastocyst thaum lub sij hawm kev loj hlob ntawm embryo. Cov hlwb no yog pluripotent. Cov kab mob embryonic kuj tseem pab txhim kho peb txheej kab mob. Laboratory-derived embryonic qia hlwb muaj peev xwm ua kom sib txawv rau ntau hom cell tshwj xeeb. Qhov kev sib txawv ntawm qhov sib txawv yog qhov sib txawv ntawm cov fetal thiab embryonic qia hlwb.
