Qhov sib txawv tseem ceeb ntawm kev tsim cov embryo twinning thiab somatic cell nuclear hloov yog tias cov embryo twinning yog cov txheej txheem hauv kev faib cov qe fertilized rau hauv ob hom embryos zoo ib yam tshwm sim nyob rau hauv vitro mob thaum somatic cell nuclear hloov yog ib qho txheej txheem nyob rau hauv uas ntxig ntawm ib tug somatic cell nucleus mus rau hauv lub enucleated qe cell yuav siv sij hawm qhov chaw nyob rau hauv lub vitro tej yam kev mob.
Molecular cloning yog cov txheej txheem tseem ceeb hauv kev tsim cov kab mob sib txuas nrog cov cim zoo. Artificial embryo twinning thiab somatic cell nuclear hloov yog ob txoj kev siv nyob rau hauv vitro tej yam kev mob rau lub hom phiaj ntawm kev tsim clones rau ob qho tib si kev loj hlob thiab kev kho mob lub hom phiaj. Txawm li cas los xij, muaj qhov sib txawv ntawm cov embryo twinning thiab somatic cell nuclear hloov mus rau hauv cov nqe lus ntawm lawv txoj kev cloning.
Dab tsi yog Artificial Embryo Twinning?
Ntsuab embryo twinning yog cov txheej txheem ntawm kev tsim cov menyuam ntxaib zoo tib yam hauv kev tsim khoom. Cov txheej txheem no ua raws li cov txheej txheem ntuj tsim ntawm ntxaib. Faib lub qe fertilized rau hauv ob cais embryos yuav siv sij hawm qhov chaw nyob rau hauv lub txheej txheem no. Ob lub embryos no loj hlob mus rau hauv ob lub fetuses. Txij li thaum ob lub embryos pib los ntawm tib lub qe fertilized, cov xeeb ntxwv tshwm sim yog caj ces zoo tib yam.
Ntsuab embryo twinning tshwm sim nyob rau hauv vitro mob. Yog li, nws txawv ntawm cov txheej txheem ntuj tsim ntawm ntxaib. Thaum pib ntawm cov txheej txheem, nws yog ib qhov tsim nyog los tshem tawm cov qe fertilized ua ntej. Tom qab ntawd, nws yuav tsum tau muab faib ua ob embryos manually. Thaum sib cais ntawm embryos, implantation ntawm embryos mus rau hauv ib tug surrogate niam yuav siv qhov chaw. Tus niam mam li nqa cov theem kev loj hlob ntawm cov menyuam ntxaib mus txog rau thaum tus menyuam yug. Ntxiv nrog rau kev tsim cov noob menyuam ntxaib zoo tib yam, txoj kev no kuj tseem siv tau rau kev tsim cov kabmob ntawm tib neeg lub cev embryonic hlwb.
Dab tsi yog Somatic Cell Nuclear Transfer?
Somatic cell nuclear hloov lossis SCNT yog cov txheej txheem uas siv cov txheej txheem ntawm kev ntxig ib lub cell nucleus rau lub qe qe qe. Thaum nkag mus rau lub qe qe, lub qe loj hlob mus rau theem blastocyst, thiab tom qab ntawd cov hlwb raug cog rau hauv kab lis kev cai nruab nrab. Somatic hlwb yog cov tsis muaj kab mob xws li tawv nqaij cell, rog cell, thiab daim siab cell thaum enucleated qe cell yog ib lub qe qe uas tsis muaj nws cov nucleus (vim ovum).
Somatic cell nuclear hloov pauv kuj yog ib qho txheej txheem hauv vitro, qhov chaw tso ntawm somatic nucleus rau hauv lub zes qe menyuam khoob tshwm sim hauv chav kuaj. Thaum loj hlob ntawm lub cell, lub cell yuav tsum tau muab tso rau hauv ib tug surrogate niam thiab tso cai rau tsim.
Daim duab 02: Somatic Cell Nuclear Hloov
Daim ntawv thov kev cog lus tshaj plaws ntawm SCNP yog lub peev xwm tsim cov kab mob sib txuas nrog cov cim zoo xws li cov kab mob tiv thaiv, kub tsis kam thiab muaj peev xwm tsim tau ntau yam muaj txiaj ntsig zoo xws li cov proteins lossis enzymes, thiab lwm yam. Tsis tas li ntawd, SCNT muaj ua ib qho tseem ceeb ntawm kev kawm hauv kev tshawb fawb qia cell. Nws kuj yog ib txoj kev nrov siv hauv tsiaj cloning.
Dab tsi zoo sib xws ntawm Artificial Embryonic Twinning thiab Somatic Cell Nuclear Transfer?
- Lawv yog cov txheej txheem cloning, yog li ob qho tib si cov txheej txheem ua rau muaj cov qauv caj ces lossis ib qho clone.
- Ob leeg ua nyob rau hauv vitro
- Cov tswv yim no yuav tsum muaj tus niam surrogate rau implantation.
- Ob leeg tuaj yeem ua rau cov kab mob sib txuas ua ke.
Qhov txawv ntawm Artificial Embryonic Twinning thiab Somatic Cell Nuclear Transfer yog dab tsi?
Txoj embryonic twinning thiab somatic cell nuclear hloov pauv feem ntau txawv ntawm cov txheej txheem uas lawv ua raws li cloning. Artificial embryonic twinning yog hais txog cov txheej txheem ntawm kev faib lub qe fertilized rau hauv ob lub embryos nyob rau hauv vitro tej yam kev mob thiaj li ua kom cov menyuam ntxaib zoo tib yam. Nyob rau hauv sib piv, somatic cell nuclear hloov mus rau lub txheej txheem ntawm inserting ib tug somatic cell nucleus mus rau hauv ib tug enucleated qe cell nyob rau hauv vitro mob nyob rau hauv thiaj li yuav ua kom ib tug recombinant kab mob nrog rau cov yam ntxwv nyiam. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev tsim cov embryo twinning thiab somatic cell nuclear hloov. Tsis tas li ntawd, kev tsim cov embryonic twinning ua rau cov txheej txheem sib tw ntuj thaum somatic cell nuclear hloov cov txheej txheem tsis ua raws li cov txheej txheem ntuj tsim.
Cov hauv qab no infographic qhia txog qhov sib txawv ntawm cov khoom tsim embryonic twinning thiab somatic cell nuclear hloov.
Summary – Artificial Embryonic Twinning vs Somatic Cell Nuclear Transfer
Txoj embryonic twinning thiab somatic cell nuclear hloov pauv yog ob txoj hauv kev siv rau cloning. Artificial embryonic twinning yog hais txog cov txheej txheem ntawm kev faib lub qe fertilized nyob rau hauv vitro tej yam kev mob los tsim ob embryos nrog zoo tib yam genetic muaj pes tsawg leeg. Nyob rau hauv sib piv, somatic cell nuclear hloov mus rau hauv cov txheej txheem ntawm inserting ib tug somatic nucleus mus rau lub enucleated qe cell thiaj li yuav qhia cov yam ntxwv tshiab rau cov kab mob. Qhov tseem ceeb tshaj plaws, kev tsim cov embryo twinning ua cov txheej txheem ntuj tsim uas tsim cov menyuam ntxaib zoo ib yam. Qhov no qhia txog qhov sib txawv ntawm qhov sib txawv ntawm cov embryo twinning thiab somatic cell nuclear hloov.
