I-Placenta Banking e-USA iMbali emfutshane
intshayelelo
Bangaphezu kwama-40,000 abantu kwihlabathi liphela abafumene a intambo yegazi stem cell uqhaqho-fakelo ukusukela ekusekweni kwayo ngeminyaka yoo-1980. Imithombo ebalulekileyo yeeseli ze-stem eziguquguqukayo ngakumbi kunezo zikhoyo kwigazi lentambo ziquka igazi le-placental kunye nezicubu.
Ezi seli stem zinokuba lunyango lwezinye izifo kwixesha elizayo, zongeza amathuba okuba ukutshintshwa kokufakelwa kuya kuphumelela ngoku. Ke ngoko, kufuneka ulondoloze i-placenta kunye neeseli ze-blood stem kusana lwakho.
Iintsapho ziyakwazi ukugcina ngakumbi iiseli zabo ezisanda kuzalwa ngenxa yegazi le-placental kunye neenkonzo zebhanki yezicubu. Basenokukwazi ukunyanga izifo ezongezelelweyo njengesiphumo kwikamva.
Indawo yokuQala
UGqr. Georges Mathé, i-oncologist yaseFransi kunye ne-immunologist, wenza Ukunyuka komongo wethambo koonjineli abathandathu baseYugoslavia abachanabeke kwimitha yemitha kwingozi yenyukliya ngowe-1958.
I-Mathé ichaza imeko ebizwa ngokuba yi-graft-versus-host disease kwaye ichonge impendulo ye-immunological enokuthintela uqhaqho-fakelo ekusebenzeni.
Iminyaka eyi-25 emva kwe-UCBT, isigulane esafumana unyango apho sisesempilweni entle kwaye sigqibe ngempumelelo ixesha elide lokuphinda uhlengahlengiso lomnikeli we-hematological kunye ne-immunological donor.
UGqr. Hal Broxmeyer kunye noogxa bakhe ekuqaleni baye bazisa ingcamango yentambo yegazi njengomthombo othatha indawo yeeseli ze-stem zofakelo kwi-1983.
Igazi lentambo yomntu liye lavezwa ukuba liqulethe iiseli ze-stem ezitshintshayo. Ukususela ngoko, kuye kwafundwa okuninzi ngendlela enokusetyenziswa ngayo igazi lentambo kunye nokusebenza kwalo kwiinkqubo zonyango.
UGqr. Douglas wenze ukuba kube nokwenzeka ukuba i-UCBT yokuqala iqhutywe ngo-Okthobha ka-1988 ekuzalweni komntwana wasetyhini owayefunyaniswe ngoxilongo lwaphambi kokubeleka ukuba akachaphazeleki kwaye u-HLA-ofana nomntakwenu owayene-FA.
Ukhuseleko kunye nokusebenza kakuhle kweeseli ze-BM ezigciniweyo zisekiwe. Kwenziwa njengonyango lomntwana oneminyaka emithandathu “oneAnemia kaFanconi.”
Ukuqala kweCord Blood Banking
INew York Blood Center yavula indawo yokuqala yokugcina igazi kawonke-wonke ngowe-1991. Sele kukho iiyunithi zokugcina igazi ezingaphezu kwama-700,000 160 ezisasazwe kwiibhanki zikawonke-wonke ezili-36 kumazwe angama-XNUMX.
Ikhono lebhanki lentambo yegazi libonelela ngeenzuzo kunye amadama axabisekileyo Iiseli ze-stem kunyango lweemeko ezifana ne-leukemia kunye ne-lymphoma.
Ubuninzi bokunikezelwa kwegazi ngentambo buyohluka kwisizwe nesizwe. Ngaphantsi kwe-5% yokuzalwa e-United States, apho malunga ne-4 yezigidi zezingane zizalwa ngonyaka, kubangela ukuqokelela igazi lentambo ukuze kunikezelwe.
Abantu baqala ukuqonda ukubaluleka kokugcinwa kwegazi kwentambo njengoko beqonda ngakumbi ukubanakho kwesi sixhobo.
Ufakelo lwegazi lokuqala lwentambo yomntu omdala lwenzeka ngowe-1995 kwiZiko lezoNyango leYunivesithi yaseDuke eUnited States kumguli weleukemia.
Ngenxa yokuba kukho iiseli ze-stem ezimbalwa kwiyunithi yegazi lentambo, ukufakelwa kwegazi kwi-umbilical cord ngaphambili kwenziwa kuphela kubantwana.
Ukukhula kweMigaqo yeGazi yeNtambo kunye neNkxaso kaRhulumente
The imithetho elawulayo ukugcinwa kwegazi ngentambo kwahluka kakhulu phakathi kwezizwe ezinazo. Ukususela kwi-2007, i-Australian Therapeutic Goods Administration (TGA) ilawula iibhanki zegazi zentambo e-Australia.
I-International NetCord Foundation kunye neNkqubo yeSizwe ye-Marrow Donor / i-BeTheMatch yenze iirejistri zamazwe ngamazwe ukukhangela intambo yeyunithi yegazi kwi-2001.
I-AABB kunye neSiseko sokuVunywa kweTherapy yeSelula ilawula imigangatho kunye nokuvunywa kwebhanki yegazi yentambo (FACT). Oogqirha kunye nabazali abakhulelweyo banokujonga ezi ziqinisekiso zebhanki.
I-Food & Drug Administration (FDA) eUnited States yapapasha imigaqo yokugqibela yokukhupha iilayisenisi zeebhanki zegazi ezivela kubaxhasi abanganxulumananga.
UMthetho osaYilwayo weCW, iNkqubo yoTshintsho lweSeli eziLutsha, wasekwa nguMthetho weStem Cell ka-2005 kwaye uqhutywa nguMbutho wezeMpilo kunye noLawulo lweeNkonzo.
Inegalelo kwiNkqubo yeSizwe yoMnikeli weMarrow/BeTheMatch intambo yegazi lobhaliso kunye neNational Cord Blood Inventory (NCBI). Ukususela kwi-1999 ukuya kwi-2004, amaziko amaninzi, uphando olulindelekileyo lwenziwa ekutshintsheni intambo yegazi kubaxhasi abangabalulekanga.
Ikamva leNgxowa-mali yeBhanki yegazi
Iintlobo zeeseli ze-stem yabantu abadala, kubandakanywa iiseli ze-pulp stem cell kunye ne-adipose-derived stem cells, zigcinwe kwiibhanki zegazi njengenxalenye yesicwangciso sokwahlukana.
The Ikamva lebhanki yegazi kwaye uphando lunokutshintsha ngokupheleleyo indlela ukhathalelo lwempilo olubonelelwa ngayo, lusenza ukuba sifikelele kunyango lwezonyango ngeqhekeza elincinci leendleko.
Ziya zisanda ngokwanda malunga nokubonelela ngeenkonzo zokugcina izihlunu ezahlukeneyo zangaphambi kokubeleka, njengegazi lentambo, i-placental, kunye ne-amnion. Ekugqibeleni, ukukhuphisana kwexabiso kuyanda. I-HealthBanks Biotech iveze elona xabiso liphantsi kwimarike e-US, eyi-19.99 yeedola ngenyanga.
Ngenye imini, kunokwenzeka ukuba udibanise kwaye uvelise kwakhona iiseli ze-stem zomntwana wakho, ezazigcinwe ebhankini ekuzalweni kwakhe, ukubagcina beziva bebatsha kwaye bekhuthele ixesha elide emva kokuba ookhokho babo behla baye kwinkundla ye-shuffleboard.
Nokuba mdala kangakanani na, oogqirha bangakwazi ukwahlula iiseli ze-stem, ukulungisa i-DNA yabantu ukulungisa iimpazamo, kwaye ngokufanelekileyo "baqalise" iinkqubo zabo zofuzo.
