Umzimba womuntu odidekile uvela kuphela kumangqamuzana amabili omzali, anethuba elikhulu lokuthuthukiswa, akhule ngokushesha futhi avela kuwo, cishe zonke izitho zomuntu zakhiwa. Zibizwa ngokuthi ama-stem cells futhi zithandeka kakhulu ososayensi, ngoba zingasetshenziswa ukuphatha izifo ezihlukahlukene. Phakathi kwazo zonke izinhlobo zama-stem cells kusuka endaweni yokubuka yokuziphatha, futhi kusukela ekubukeni kokuhambisana nomuntu othize, okuthembisayo kakhulu igazi elivela emthonjeni we-umbilical.
Igazi lezintambo
Igazi elivela emthonjeni we-umbilical ingenye yemithombo esemqoka yamaseli we-hematopoietic. Lawa maseli ayingxenye yegazi futhi ahlinzeke nge-oxygen kwezidingo, kanti futhi anesibopho sokusebenza kwamasosha omzimba. Ngesikhathi esifanayo, lapho lawa maseli efakwa khona, odokotela bathola imiphumela ehluke emiphumeleni yokufakelwa komnyofu wamathambo, ngisho nakubanikeli abasondelene, ngendlela engcono kakhulu. Okungajwayelekile kakhulu amacala okungahambisani. Ama cell stem wengane cishe kufanele afanele ukwelashwa kwabantwana bakhe. Yingakho ukulondolozwa kwentambo yegazi kungokuqala kokunakekela impilo yengane.
Isampuli sezintambo zesitembu ekulethwa
Namuhla, isampula legazi lezintambo lwenziwa ezibhedlela ezinkulu zokubeletha nasezikhungweni zendawo yokulala, lapho amangqamuzana angagcinwa khona ebhange. Ngaphezu kwalokho, kunamabhange amaningana angaphandle, kanye nokuthi kungenzeka yini ukuhlela ukuqoqwa kwegazi lomthambo wegazi. Emazweni amaningi, abameleli bamabhange anjalo basebenza, okunikeza izimo ezanele nezibonakalayo
Ukuze uthathe igazi emthonjeni we-umbilical, akudingeki uxoxisane nebhange kuphela, kodwa nodokotela esibhedlela lapho uhlela ukuzala khona. I-sampling yegazi kumele yenziwe ngokushesha ngemuva kokuzalwa komntwana, kubalulekile ukuthi usebenze ngokushesha, futhi kubalulekile ukulungiselela kusengaphambili.
Kungani ugcine igazi lezintambo? Lena yomshuwalense wokuphila kwengane yakho, kungenzeka ukuthi ukwelashwa okuphumelelayo nokushesha kwezifo eziyinkimbinkimbi. Lokhu kuyiqiniso ikakhulukazi ezinganeni ezisengozini, eziye zabhekana nezifo ezinzima emindenini yabo.
