Kungani intambo igazi?

Namuhla wezwa stem cells, uma kungewona wonke, abaningi kakhulu. Sinesithakazelo ngokukhethekile yilona isihloko abazali esizayo abaku- indlela izinqumo ekulondolozweni kwezindawo enkabeni intambo igazi izingane zabo ezisanda kuzalwa. On the ngokunemba abalithandayo kungaya ngqo nempilo yengane.

Ake sixoxe kungani intambo igazi lilondolozwe izimbiza ekhethekile. Ngaphezu kwalokho, cabanga izici zayo futhi izicelo.

Kuyini enkabeni intambo igazi?

Igama elinikeziwe igazi ethathwa umzanyana kanye umntwana placenta ngokushesha emva kokuzalwa. Inani lawo emakamu eliphezulu ama-stem cell, okuyinto abe sebuningini izici ezinhle.

Yiziphi stem cells

amaseli Cord egazi kuthiwa stem. Bangabaholi main "amabhlogo wokwakha" ukuba kwakhiwe isimiso somzimba sokuzivikela ezifweni. Ngaphezu kwalokho, ama-stem cell ibe isici ezithakazelisayo ukuthi kungenzeka besigaba lonke umjikelezo wokuphila. Lokho kwenza ukubuyiselwa kwanoma iyiphi izicubu zomzimba. Futhi ekunqandeni amaseli uyakwazi umehluko ngokuphelele kunoma iyiphi enye uhlobo cell, okuyinto has engaphezu kwamakhulu amabili.

Kangakanani umzanyana nokuqoqwa kwegazi

Ngakho, kufanele ukuqoqa indlela igazi intambo? Ngokushesha kufanele kuphawulwe ukuthi lokhu Inqubo kobuhlungu ngokuphelele umama usana lwakhe obelusanda kuzalwa. Ngaphezu kwalokho, ongaqhubeki iyiphi ingozi.

Ngokushesha ngemva ukulethwa enkabeni umthambo inaliti eyayifakwa lapho igazi odlula phansi iphakheji ekhethekile. Kuyo vele iqukethe okusamanzi okungaphathwa kuvimbela ekunqandeni. amahlamvu lonke kusuka 50 kuya 250 ml igazi lapho Ukwakheka iqukethe kusuka 3 kwabangamaphesenti angu-5 ama-stem cell.

Ngemva ukudedelwa placenta ukusikeka obelethisayo ka mayelana 10-20 amasentimitha of umzanyana kanye usibeka esitsheni akhethekile.

Zonke biomaterials kumele uthunyelwe elabhorethri amahora 4-6. Kukhona uya ukucubungula kwabo, umnkantsha nokubeka ku-USB.

Impilo ka-stem cell kanye nokusetshenziswa yabo

Ukugcina intambo igazi - inqubo okufanele kwenzeke ngayo yonke imithetho efaneleko neziqondiso. Phela, kuncike kuye ngesikhathi "ukuphila" ka-stem cell.

Uma agcinwe kahle, le nkathi kungenzeka amashumi eminyaka, njengoba kufakazelwa iqiniso lokuthi ibhange igazi lokuqala wavulwa emuva ngo-1993. Yingaleso kusukela ngaleso sikhathi kuze kube isikhathi sethu zigcinwa aqale ayiswa khona ama-stem cell kusukela enkabeni intambo igazi.

Iqiniso lokuthi leli biomaterial by 100% okwengeziwe efanelekayo ngqo ingane, kungaba akunakungatshazwa. Ngaphezu kwalokho, ucwaningo olwenziwa lukhombisa ukuthi ukusetshenziswa ketshezi oluyigugu unga eziseduze (abazali, abafowethu nodade). Kulokhu, amathuba ukuthi igazi kuyinto ekahle, luphakathi 25%.

Stem lamaseli womuntu omdala

Ngemva kokufunda le mininingwane engaphezulu, kungase kuphakame umbuzo: kungani stem cells udinga ukuqoqa it kusuka usana olusanda kuzalwa? Aziyona yini emzimbeni womuntu omdala? Yebo zikhona. Kodwa!

Umehluko omkhulu itholakala lokuhlushwa stem cells egazini. Njengoba bekhula, inani labo njalo ngincipha. Lokhu kuzosiza ukuqinisekisa ukuthi imiphumela yocwaningo: 1 e izinsana ekunqandeni cell-akhawunti 10,000 kumaseli emzimbeni phakathi nenkathi yokuqhuma kobusha - abayizinkulungwane 100, futhi ngemva kweminyaka engu-50 - 500 ayizinkulungwane. Lokhu kunciphisa hhayi kuphela inombolo kodwa futhi izinga. Enkabeni intambo stem cells abakhuthele abangaphezu kuka-naleyo etholakala umnkantsha. Isizathu esikhulu salokhu ebusheni babo.

Kuqakatheke ngani ukugcina igazi umzanyana

imithi yesimanje seyithuthuke kude phambili uyazi okuningi. Kodwa namanje kukhona ezinye izifo, ikhambi okuyinto ayikatholakali kuze kube yasungulwa. Ezimweni ezinjalo, indlela yokuphuma ukusebenzisa enkabeni intambo igazi, noma yini ukunemba kakhudlwana - stem cells equkethwe kuwo. Ngokwesibonelo, kungase kube izifo kwesimiso somzimba sokuzivikela ezifweni. Lokhu kungenzeka futhi ihlanganisa futhi ezimweni lapho yokutakula liyadingeka umnkantsha noma igazi, kanye biomaterial isetshenziswa ingayala izicubu ukuvuselelwa ngemva othola ukusha olunzulu noma izilonda.

Ngisho noma ingane yazalwa engumqemane, akuqinisekisi ukuthi amaseli stem ngeke kudingeke kuye ukuze bathole ukuphila. Ngaphezu kwalokho, angasetshenziswa ukwelapha okuthile kwezihlobo eziseduze. Ngakho-ke nibaluleke ukucabanga mayelana intambo nokuqoqwa kwegazi inkinga ngaphambi ukulethwa ukuze uvumele lapho nje kugcine impilo ingane, kodwa futhi nezinye amalungu omndeni.

Ukwelashwa nokuvikelwa enkabeni intambo igazi

Kwakuthinta eshiwo ngenhla ukuthi enkabeni intambo igazi kanye stem cells okumunyethwe kuwo, kukhona panacea sangempela ukususa izifo eziningi ezinkulu. Kodwa ngaphandle izibonelo eziqondile yamazwi anjalo uzohlala nje ibinzana awunalutho. Ngakho-ke, masikhumbule ezinye izifo ezivame kakhulu (nakuba wonke zabo ezingaphezu kuka-80), kusuka lapho kungenzeka ukuqeda ngokusebenzisa le biomaterial. Ukuze kube lula, zizokwenziwa zibe zihlukaniswe ngamaqembu ezihlobene.

Izifo yegazi:

• lymphoma;
• hemoglobinuria;
• futhi refractory anaemia aplastic;
• isikela cell anemia;
• Waldenstrom;
• hemoglobinuria paroxysmal ebusuku;
• oyingozi futhi ezingalapheki wegazi ;
• anaemia Fanconi;
• macroglobulinemia;
• myelodysplasia.

izifo sokuhlasela kwamasosha omzimba:

• rheumatoid arthritis;
• cerebral palsy;
• umgogodla cord yokulimala;
• unhlangothi;
• Alzheimer;
• ukuqina kwamathishu letindzala;
• izifo sezinzwa uhlelo;
• Parkinson.

Cancer:

• unesimila ebuchosheni;
• umdlavuza (webele, izinso, esibelethweni, testes);
• encane umdlavuza cell wamaphaphu ;
• Sarcoma Ewing sika;
• rhabdomyosarcoma;
• ebuchosheni;
• thymoma.

Ezinye izifo azalwa naso futhi wathola:

• iziyaluyalu umzimba;
• immunodeficiency;
• sikashukela;
• sokuwohloka kwemisipha;
• isifo sokusha;
• AIDS;
• histiocytosis;
• amyloidosis.

izinkomba Specific kanye contraindications ukuze kulondolozwe enkabeni intambo igazi

Kunezimo lapho udaba wokusindisa intambo igazi kudinga ukunakekelwa okukhethekile. Lokhu kusebenza ezimweni lapho:

• amalungu omndeni yizona ezimelela bezizwe ezihlukahlukene;
• unazo umndeni kutholakala ukuthi uphethwe yini yegazi noma esibulalayo;
• emndenini izingane eziningi;
• umndeni kakade ezinempilo enhle;
• ukukhulelwa kwenzeka ngemva IVF;
• kukhona izinsolo ukuthi isidingo ukusetshenziswa stem cells kungenzeka esikhathini esizayo.

Kodwa futhi kwenzeka ukuthi silondoloze stem cells akuvunyelwe. Lona uma yalokho emihle khona izifo ezifana ne-hepatitis B no-C, ugcunsula, HIV-1 ne-HIV-2, T-cell wegazi.

Yeka ukuthi yaphumelela kanjani ukwelashwa nge-stem cell?

Sekuyisikhathi eside ososayensi babesazi izici ewusizo lowo igazi intambo. Futhi kuze kube manje, ucwaningo asebenzayo ekusetshenzisweni stem cells ukwelapha izifo ezehlukene. Kuyaphawuleka ukuthi iyathuthuka nasesikhathini sibonga eduze esizayo kuze kube segazini intambo sizokwazi ukuqeda izifo eziningi. Ngaphezu kwalokho, ungakwazi ukhule entsha umzimba ephezulu grade endaweni yokucwaninga kusuka stem cells! Ukutholakala kwaleli qiniso seyithuthuke kude phambili imithi wafaka wakhe, ngomqondo ongokomfanekiso, isigaba esisha yokuziphendukela kwemvelo.

Uyini Bank of stem cells, futhi wenzani?

Uma Kwanqunywa ukuba alondoloze igazi intambo, luhlala ukubhekana umbuzo owodwa kuphela: kuyokwaziwa agcinwe lapho? Zikhona izindawo ezikhethekile izinjongo ezifana? Impendulo Yiqiniso, omuhle.

Bank intambo igazi stem cells - indawo lapho izinto eziphilayo azithathe eliyigugu izogcinwa kuhambisana zonke amazinga adingekayo. Nokho, kukhona usomqulu amabili: okuzisholo futhi umphakathi.

Esimweni sokuqala, igazi umzanyana wengane kungokwalabo abazali bakhe, futhi bachithe uma abangakwenza. Kodwa kulesi simo, kuyodingeka ukhokhe wonke amasevisi abo, kuqala ukuqoqwa nokucubungula ziphethe USB.

Stem cells kungenzeka irejista omphakathi atholakele kunoma yimuphi umuntu uma kuvela isidingo.

Ukukhetha yasebhange stem cells

Lapho ekhetha yasebhange lwama-stem cell isitoreji kuyadingeka ukugxila amaphuzu ambalwa ezibalulekile. Ake sicabangele ngayinye yalezi zinkulumo ngokuningiliziwe.

1. Bank bokuba khona isikhathi. Kule ndaba, konke okunengqondo, ngoba isikhathi esiningi le nhlangano esebenza ngayo, kulapho wayethembele amakhasimende, ikakhulukazi ngenxa yokuqiniseka e kungapheli kwato. Ngaphezu kwalokho, abasebenzi asebhange kujwayele ukuthi olutheni nge intambo igazi.
2. Onelayisensi. Lena okumele abonwe uya khona. Ibhange kumele unemvume kocingo, ezokuthutha kanye isitoreji stem cells, okuye esikhishwe yikomidi Impilo.
3. izindawo Base. Kungcono ukukhetha ibhange kusekelwe yesayensi socwaningo noma isikhungo sakho sezokwelapha. Lokhu kuzoqinisekisa ukuthi banayo yonke imibandela ngokusebenzisana izinto eziphilayo azithathe futhi isitoreji ifinyelelwe.
4. Ukuba khona nezinto ezidingekayo. Ibhange kumele ifakwe Centrifuge double, kanye kumadivayisi futhi Sepax Macopress.
5. Ukuba indawo elawula uhlelo okuzenzakalelayo cryostorages. Lokhu kuzosiza ukulawula amasampula Igumbi lokushisa enkabeni intambo igazi, kanye imibiko kwisitoreji ufakwe yomlando ekhethekile.
6. Ukuba khona service ehambisa izincwadi. Lokhu kwenzelwa ukuqinisekisa ukuthi abasebenzi ibhange kungaba isinyathelo masinyane ewadini, ukuqoqa igazi cord bese bekuthuthela lab. On ijubane umsebenzi wabo ngqo ukusebenza okuqhubekayo stem cells kuncike.
7. Ukuqhuba ucwaningo emkhakheni ucwaningo yasebhange cell ubuchwepheshe. Lokhu isigaba kubaluleke ngaphezu kwanoma ubani omunye. Ngaphezu kwalokho, ibhange kumelwe sibambisane nezikhungo zezokwelapha futhi ehola ucwaningo nezikhungo komuzi.
8. Ukuba khona unogada. Le nto ayidingi incazelo eyengeziwe.

Ngaphezu kwalokho, ungakwazi ukuzikhethela ucacise ukuthi isipiliyoni yebhange ekusebenziseni ama-stem cell ukwelashwa. Ukuba asabele kahle ngeke nje kube omunye plus.

Lapha thina bayawazi umbuzo "Uyini enkabeni intambo igazi." Ukusetshenziswa kwalo, njengoba sibona, kuvezwa for ekwelapheni izifo ezingathi sína kwababhemayo lapho izidakamizwa kakade engenamandla. Kodwa noma kunjalo, isinqumo sendlela ukuqoqa igazi intambo izingane zabo ezisanda kuzalwa noma cha, ukuthatha kuphela abazali bakhe.
