Imisebenzi yezintambo zombilical

Umthambo ubalulekile ukuthi ukukhulelwa kuqhutshwe kuqedwe ngoba uphethe ingane yokondliwa nge-placenta. Luhlobo lweshubhu elingama-56 cm ubude no-1 kuye ku-2 cm ububanzi. Umthambo uqukethe imithambo emikhulu nemithambo esebenza ukushintshanisa izakhamzimba negazi eline-oxygen.

Ngesikhathi sokukhulelwa kungaba nezinkinga entanyeni, kwakha amafindo angamanga angenakubaluleka komtholampilo, kepha kungahle kube nezinye izinkinga ngamafindo angaholela ekufeni kwengane.

Phambilini ngemuva kokubeletha izintambo zombilical zazilahliwe, namuhla amangqamuzana esiqu aqukethwe enkabeni asetshenziselwa izinhloso zokuphulukisa njengomdlavuza, i-leukemia phakathi kwezinye izifo. Omama bangakhetha ukuyibeka ebhange lezintambo zegazi ukuze iqhubeke iphila futhi ikwazi ukuyisebenzisa uma kunesifo somndeni (ukukhokha imali) noma ukunikela ngayo ukuze abanye abantu babe nenhlanhla yokuthola ukwelashwa .

Kungashiwo ukuthi amangqamuzana enkaba acishe ayisimangaliso yingakho isayensi inesifiso sokuqhubeka nokutadisha zonke izakhiwo zazo. Ngokulandelayo ngizokuchazela konke lokhu ngemininingwane ethe xaxa ukuze ungaqondi nje kuphela imisebenzi yenkaba kepha futhi ukubaluleka ezimpilweni zezingane ezingakazalwa, nokubaluleka esinakho namuhla ukukwazi ukwelapha ezinye izifo.

Intambo yenkaba

Inkaba isebenza izinyanga eziyisishiyagalolunye ukunikeza ingane yakho impilo, bekulokhu kunjalo ukuhlinzeka nge-oxygen nezakhamzimba ngalokho okwazile ukuthuthuka futhi kwaba ingane yakho eyigugu. Lapho ingane izalwa inkaba iyanqunywa bese iqala ukoma futhi izowa cishe emasontweni amathathu kuye kwayisithupha, inikeze inkinobho yesisu sengane yakho.

Indima yenkaba

Kungabonakala ngathi ucezu lwenyama olungaphezudlwana kuka-56 cm kepha lungaphezulu kakhulu kwalokho ocabanga ukuthi. Intambo yenkaba inomsebenzi oyinhloko wokuhlanganisa umntwana okhulayo nonina, obaluleke kakhulu ekugcineni umntwana ephila esibelethweni.

Umkhawulo owodwa wentambo yenkaba unamathiselwe enganeni bese kuthi omunye ungene kwi-placenta, esondele kakhulu odongeni lwesibeletho, ivumela ukudluliswa kokudla phakathi kukamama nengane futhi ngasikhathi sinye iqinisekisa ukuthi ayihlangani negazi.

Nge-placenta, i-oxygen nezakhamzimba zithola indlela yazo yokondla ingane, kuyilapho i-carbon dioxide nemikhiqizo kadoti ihamba iye kolunye uhlangothi kunina futhi iyakhishwa.

Kubalulekile empilweni yengane

Inkaba ibalulekile ukugcina ingane iphila. Imvelo ihlakaniphile futhi inkaba isongwe ngohlobo lwe-gelatin enika amandla nokumelana nentambo ukuze ingazigoqeli futhi ingabi amafindo. Yize kunamacala aziwayo avela futhi angadala nokufa kwengane, njengoba ngishilo ekuqaleni kwendatshana.

Intambo yenkaba ingagoqa intamo yengalo, izingalo nemilenze nganoma yisiphi isikhathi ngesikhathi sokukhulelwa nokubeletha, okuthile okuzodingeka ukuthi kubhekwe ngokucophelela. Ngamawele abelana ngesaka elifanayo le-amniotic, izintambo zingabambana futhi zidale izinkinga ezinkulu.

Ukunyakaza okujwayelekile ngaphakathi kwesibeletho kwesinye isikhathi kungabopha amafindo entanjeni, okuthi uma kuqinisiwe kungamisa ukugeleza kwegazi kume namahlule egazi ngaphakathi kwemikhumbi, okungancisha ingane umoya-mpilo noma izakhamzimba.

Umthombo ocebile wamaseli we-stem

Amaseli ama-embryonic stem, angamaseli angahlukanisiwe, angamaseli engane ekhulayo anamandla amakhulu acishe abe yisimangaliso ngoba angaba yiluphi uhlobo lwamangqamuzana omzimba, esikhumba, izicubu zemizwa zamaseli akha inhliziyo noma inso.

Kube nocwaningo oluningi ukuthola ukuthi kanjani sebenzisa kangcono amaseli aqukethwe ezintanjeni zezimbambo ukuze akwazi ukwelapha izifo ezifana neleukemia yengane, kepha zinikezwa nokunye ukusetshenziswa njengokuphatha ukulimala komgogodla, isifo senhliziyo, nesifo sobuchopho. Ngalesi sizathu, abanye abazali bakhetha ukugcina igazi labo lenkaba emabhange azimele noma kahulumeni.

Emabhange kahulumeni (noma emabhange omphakathi) izintambo zomxhaso ezinikelwe ziyatholakala kunoma ngubani odinga usizo nokuthi iyahambisana, futhi uma umuntu onikelile edinga ukusetshenziswa kwayo nganoma yisiphi isikhathi, kuzofanele bathole eyodwa ehambisanayo ukuze bazuze ngokunikela ngenkaba ngaleso sikhathi.

Njengoba ubonile, inkaba ingaphezulu kakhulu kwentambo elula, ingumthombo wokuphila ohlanganisa umama nengane ukuze kunikezwe isimangaliso sempilo. Futhi uma lokhu bekunganele, ngaphezu kokusebenza kwayo okuyinhloko emvelweni, futhi kunamandla anele okusindisa izimpilo zabanye abantu abagulayo.

Unabantwana? Uma kunjalo, ngabe unikele ngenkaba ebhange lomphakathi noma ubufuna ukuyinikelela eyimfihlo ukuze ukwazi ukuyisebenzisa ngesikhathi ongase uyidinge ngayo?

Ngikucabangela ngempela lokho intambo imvelo isesimweni sayo esimsulwaUngu-generator wempilo ezincelisayo, yilokho okusisizayo ukuze izinhlobo zethu ziqhubeke nokuzalwa futhi ziguquke emhlabeni wethu. Futhi uma sonke singama sicabange ngokubaluleka kwempilo nokuziphendukela kwemvelo, singahlonipha impilo yomuntu nanoma yimuphi umuntu ophilayo ngokwengeziwe. Imvelo ihlakaniphile futhi inkaba iyisibonakaliso esihle sayo.
