I-Placenta Banking e-USA Umlando omfushane
Isingeniso
Abantu abangaphezu kuka-40,000 emhlabeni wonke bathole a i-blood stem cell ukufakelwa kusukela ekuqaleni kwawo-1980. Imithombo ebalulekile yama-stem cells aguquguqukayo kunalawo akhona egazini lezintambo ahlanganisa igazi le-placenta nezicubu.
Lawa ma-stem cell angaba yimithi yokwelapha ezinye izifo esikhathini esizayo, okwandisa amathuba okuthi ukufakelwa kabusha kuzophumelela manje. Ngakho-ke, kufanele ulondoloze i-placenta kanye namangqamuzana egazi entambo enganeni yakho.
Imindeni inamandla okugcina ama-stem cells amaningi ngenxa ye-placenta blood kanye nezinsiza zokubhanga izicubu. Bangase bakwazi ukwelapha izifo ezengeziwe ngenxa yalokho esikhathini esizayo.
Iphuzu Lokuqala
UDkt. Georges Mathé, udokotela womdlavuza waseFrance kanye nodokotela wamasosha omzimba, uyadlala ukufakelwa umnkantsha konjiniyela abayisithupha baseYugoslavia abachayeka emisebeni engozini yenuzi ngo-1958.
I-Mathé ichaza isimo esaziwa ngokuthi yi-graft-versus-host disease futhi ikhomba impendulo ye-immunological engavimbela ukufakelwa ukuthi kusebenze.
Iminyaka engu-25 ngemva kwe-UCBT, isiguli esathola ukwelashwa lapho sisenempilo enhle futhi siqede ngempumelelo ukubuyiselwa kabusha kwabanikezeli be-hematological kanye ne-immunological donor yesikhathi eside.
UDkt. Hal Broxmeyer kanye nozakwabo ekuqaleni bethula umbono wegazi lentambo njengomthombo othatha indawo wama-stem cells okufakelwa kabusha ngo-1983.
Igazi lentambo yomuntu liye lavezwa ukuthi liqukethe ama-stem cell transplantable. Kusukela ngaleso sikhathi, kuye kwafundwa okuningi mayelana nokusetshenziswa okungenzeka kwentambo yegazi kanye nokusebenza kwalo ezinqubweni zezokwelapha.
UDkt. Douglas wakwenza kwaba nokwenzeka ukuba i-UCBT yokuqala yenziwe ngo-Okthoba 1988 ekuzalweni kwengane wesifazane eyayinqunywe ukuxilongwa ngaphambi kokubeletha ukuthi ayithintekile futhi i-HLA efana nengane yakubo ene-FA.
Ukuphepha nokusebenza ngempumelelo kwamaseli e-BM e-cryopreserved kwase kusungulwe. Kwenziwa njengohlobo lokwelapha enganeni eneminyaka eyisithupha ubudala “ene-Fanconi’s Anemia.”
Ukuqala kweCord Blood Banking
INew York Blood Center yavula indawo yokuqala yomphakathi yokugcina igazi ngo-1991. Kakade sekunezintambo zokugcina igazi ezingaphezu kuka-700,000 160 ezisakazwe phezu kwamabhange omphakathi angu-36 emazweni angu-XNUMX.
Ikhono lasebhange intambo igazi inikeza izinzuzo kanye amadamu ayigugu Amaseli we-stem ekwelapheni izimo ezifana ne-leukemia ne-lymphoma.
Ukuvama kokunikelwa kwegazi ngentambo kuyehluka kuye ngokwezizwe. Ngaphansi kuka-5% wokuzalwa e-United States, lapho kuzalwa izingane ezingaba yizigidi ezi-4 ngonyaka, kubangela ukuqoqwa kwegazi lezintambo ukuze kunikelwe.
Abantu sebeqala ukuqonda ukubaluleka kokugcinwa kwegazi kwentambo njengoba sebeqaphela kakhulu amandla alo mthombo.
Ukufakelwa igazi okokuqala ngentambo yomuntu omdala kwenzeka ngo-1995 eDuke University Medical Center e-United States esigulini se-leukemia.
Ngenxa yokuthi kukhona ama-stem cells ambalwa eyunithi yegazi lentambo, ukufakelwa kwegazi kwentambo ye-umbilical ngaphambilini kwenziwa kuphela ezinganeni.
Imithethonqubo Yegazi Lokukhula kanye Nokwesekwa kukaHulumeni
The imithetho ebusayo i-cord blood banking ihluke kakhulu phakathi kwezizwe ezinazo. Kusukela ngo-2007, i-Australian Therapeutic Goods Administration (TGA) ilawule amabhange egazi ezintambo e-Australia.
I-International NetCord Foundation kanye ne-National Marrow Donor Program/BeTheMatch badale ukubhaliswa kwamazwe ngamazwe okubheka okufanayo kweyunithi yegazi lezintambo ngo-2001.
I-AABB kanye ne-Foundation for the Accreditation of Cellular Therapy baphatha amazinga kanye nokugunyazwa kwe-cord blood banking (FACT). Odokotela nabazali abakhulelwe bangabheka lezi ziqinisekiso zasebhange.
I-Food & Drug Administration (FDA) e-US ishicilele iziqondiso zokugcina zokunikeza amabhange egazi amalayisense kubanikezeli abangahlobene.
Umthethosivivinywa we-CW, Uhlelo Lokutshalwa Kweseli Entsha, wasungulwa uMthetho Weseli Ye-Stem wezi-2005 futhi uqhutshwa yi-Health Resources and Services Administration.
Inikela kuHlelo Lokunikela Ngomnyombo Kazwelonke/BeTheMatch intambo yegazi lokubhalisa kanye ne-National Cord Blood Inventory (NCBI). Kusukela ngo-1999 kuya ku-2004, izikhungo eziningi, ucwaningo olulindelekile lwenziwa ekufakeni igazi lentambo kubanikeli abangahlobene.
Ikusasa Le-Cord Blood Banking
Izinhlobo zamaseli e-stem asebekhulile, okuhlanganisa ama-pulp stem cell amazinyo kanye nama-stem-derived-derived stem cells, agcinwa emabhange egazi njengengxenye yesu lokuhlukahluka.
The ikusasa le-cord blood banking futhi ucwaningo lungashintsha ngokuphelele indlela ukunakekelwa kwezempilo okunikezwa ngayo, okusenza sikwazi ukufinyelela ukwelashwa ngenani elincane lezindleko.
Ziya ngokuya ziba yisipesheli mayelana nokuhlinzeka ngezinsiza zokugcinwa kwezicubu ezahlukene zangaphambi kokubeletha, njengegazi lentambo, i-placental, ne-amnion. Ekugcineni, umbango wamanani uyanda. I-HealthBanks Biotech iveze inani eliphansi kakhulu emakethe e-US, elingama- $19.99 nje ngenyanga.
Ngolunye usuku, kungase kwenzeke ukuhlanganisa nokwethula kabusha ama-stem cells engane yakho, ayegcinwe ebhange ngesikhathi izalwa, ukuze ayigcine ezizwa emusha futhi ekhuthele isikhathi eside ngemva kokuba okhokho bayo beye enkantolo ye-shuffleboard.
Kungakhathaliseki ubudala, odokotela bangakwazi futhi ukuhlukanisa ama-stem cells, balungise i-DNA yabantu ukuze balungise amaphutha, futhi “baqalise kabusha” ngempumelelo izinhlelo zabo zofuzo.
