Ukufakelwa of stem cells kanye nendima yabo imithi yesimanje

Isiqu cell kwezitho - indlela entsha ngokuphelele futhi ngempumelelo ukwelapha ezihlukahlukene izifo. Ngesikhathi idatha emhlabeni wonke-ke kusaqhubeka uphenyo, ezisiza ukuthola facets entsha lokhu kwelashwa.

Stem cells - umuntu nedifferentsiirovannye izakhiwo aqukethe izakhi zofuzo zayo. Ngaphansi kwezimo ezithile, basuke iguqulwe ibe iyiphi amaseli oyifunayo zomzimba womuntu, ngaleyo ndlela abakwazi ukubamba iqhaza ukuvuselelwa, ukwakheka kwezicubu entsha eziyishumi nemitshingo. izakhiwo ezinjalo zitholakala zonke izinto eziphilayo, kodwa njengoba yenzeka ucede ngokwabo. Abantu abaningi stem cells egazini nezicubu umntwana osanda kuzalwa.

Kuze kube manje, ekunqandeni cell kwezitho - akuyona kuphela ngempumelelo kakhulu, kodwa ngezinye izikhathi kuphela indlela ephumelelayo yokwelapha. Inqubo efanayo yayisetshenziswa for ekwelapheni izifo sokuhlasela kwamasosha omzimba (lupus erythematosus, yi-multiple sclerosis , njll), ephelezelwa impendulo sihlale siphilile of izicubu zomzimba siqu. Okokuqala, abantu stem cells kususwa, kulandele nokwelashwa ngamakhemikhali, lapho bonke komdlavuza afe. Kuphela ngemva kwalokhu nesineke futhi injected impahla eqoqwe ngaphambili - amaseli, izicubu omzimba ziqale ukusebenza ngokujwayelekile.

Ukwelapha okunjalo isetshenziswa uqine Izilonda - ukusha, izilonda, njll nesineke Human utshalwe stem cells ukuthi Zichayeké-matrix ezifanele. Njengoba ekwelapheni amaseli kugucula, kuyashesha ukuvuselelwa kwesikhumba. Zifakwe leli su ekwelapheni izifo amalunga omzimba.

Ukufakelwa of stem cells futhi kahle ekwelapheni izifo zenhliziyo nemithambo yegazi. Ngokwesibonelo, i-senhliziyo esilimele omdala ilahlekelwa amandla abo okuphila umlilo ngokushesha indlela yokuzivuselela. Ngakho-ke, ngemva kokushaywa yinhliziyo noma yimuphi omunye umonakalo izicubu senhliziyo esilimele uhlala izibazi inelastic, okuyinto izinkinga kakhulu umsebenzi emzimbeni. Nge isingeniso esifike stem cells waphawula ukuvuselelwa sithuthukiswe kwezicubu esivimba amanzi - lokhu kuvimbela imiphumela kungenzeka kanye nezinkinga lesi sifo.

Kusebenza lwama-stem cell ukufakelwa futhi ukuhlinzwa plastic, kanye isikhumba kokuqina kanye rejuvenation. Leli thuluzi nemiphumela engcono futhi akunazingozi kuka abavamile ukuhlinzwa isikhumba.

Kodwa njengoba kuye kwashiwo, wonke amathuba lokhu ukwelashwa ingakamiswa wakwambula, njengoba izifundo global olwenziwa kuze kube manje. Ngokwesibonelo, kukholelwa ukuthi ngosizo stem cells ekwelapheni isifo sikashukela, isifo i-Parkinson, ukuqeda imiphumela ukubheduka ukulimala ebuchosheni futhi umgogodla, kanye ukulungisa noma iyiphi izicubu.

Ngakolunye uhlangothi, amaseli stem kukhona izithombe cloning emizimbeni ucwaningo.

Stem cells - uhlobo panacea ezihlala njalo ezikwaziyo ukubuyisela impilo, ngisho nalabo ngaphambili kubhekwe esasizobhujiswa. Kodwa okwatholwa ezinkulu kodwa ekoneni.

Kepha umthombo stem cells - okungukuthi umnkantsha, kusukela lapho iningi omdala ngayo. Prakthiza ukufakelwa njengoba amaseli ayo kanye amasampula othathwe abanikelayo. Impumelelo inqubo kuxhomeke ezicini eziningi.

Omunye umthombo - kuyinto le enkabeni intambo igazi. Ezweni Sekuyisikhathi eside eyayiqhutshwa ucingo futhi isitoreji igazi esinomhlapho, equkethe inqwaba stem cells. Ziyakwazi efanelekayo ekwelapheni ingane esanda kuzalwa, kodwa lungasetshenziswa ku nokuvuselelwa yakhe nabafowabo, nawodadewabo, namtjhana ezinye iinhlobo.

Lokugcina stem cells Kwenziwa emitholampilo ekhethekile lapho agcinwa ngaphansi kwezimo ezifanele - at -196 degrees Celsius. Indaba iyatholakala kubanikazi kwesidzingo.
