Hauv chav kuaj, cov kws tshawb fawb muaj cloned qia hlwb los ntawm tib neeg daim tawv nqaij thiab qe hlwb. Qhov no yog qhov tseem ceeb vim qhov txheej txheem ua tau thaum kawg siv los tsim lub cev lossis lwm qhov chaw uas zoo ib yam li tus neeg mob tus kheej, thiab yog li ntawd, tsis muaj kev pheej hmoo ntawm kev tsis lees paub thaum hloov pauv.

Ua raws li qhov no, yuav ua li cas cloning lub cev cawm neeg txoj sia?

Thawj zaug cov kws tshawb fawb tau hloov cov tawv nqaij ntawm cov neeg laus mus rau hauv cov qia hlwb, uas ua tau loj hlob mus rau txhua hom ntaub so ntswg hauv lub cev. Tib neeg cloning tau siv rau tsim cov qia hlwb rau cov neeg laus thawj zaug nyob rau hauv ib tug breakthrough uas ua tau coj rau cov ntaub so ntswg thiab lub cev ua regrown.

Kuj Paub, cov txheej txheem dab tsi yuav raug siv los clone tib neeg? Cloning siv somatic cell nuclear hloov chaw (SCNT) [1]. Qhov no txheej txheem pib nrog kev tshem tawm ntawm chromosomes los ntawm lub qe los tsim ib lub qe enucleated. Cov chromosomes yog hloov nrog ib tug nucleus coj los ntawm ib tug somatic (lub cev) cell ntawm tus neeg los yog embryo los ua. cloned.

Ntxiv mus, nws raug nqi npaum li cas los clone ib tug tib neeg?

Zavos ntseeg tias kwv yees tus nqi ntawm tib neeg cloning yuav tsawg kawg $50, 000 , cia siab tias yuav poob rau hauv tus nqi mus rau thaj tsam ntawm $ 20, 000 txog $ 10, 000, uas yog kwv yees tus nqi ntawm in vitro fertilization (Kirby 2001), txawm hais tias muaj lwm yam kwv yees li ntawm $ 200, 000 rau $2 lab (Alexander 2001).

Stem cells puas tuaj yeem tsim cov kabmob tshiab?

Embryonic qia hlwb tuaj yeem ua ib qho lub cev hauv lub cev thiab ua Yog li thaum cog rau hauv blastocyst. Nyob rau hauv txoj cai, ces embryonic qia hlwb tuaj yeem siv los hloov ib qho twg lub cev hauv lub cev.
