Lobomi kweeseli stem: Ngaphambi & Emva

Nabani na, kungakhathaliseki ibala lolusu, isini, inkolo kunye nezinye iimpawu dream uhlale ulusana elide kangangoko kunokwenzeka. Izigidi izazinzulu lonke ixesha besebenza nge-kokudalwa 'lichiza ulutsha. " Kule ndawo, kukho nkqu uphuhliso kwamnandi ngokwenene ukuba isekelwe ikhula amalungu amatsha, nano-technology njalo njalo.

Umbuzo ezibalulekileyo lobomi umntu uba emva kweminyaka emashumi mane, nangona kukho abantu phezu imibimbi asahlumayo aqale yakuzixhalisa malunga kakade, kunye 30. Apha, yonke into ixhomekeke emntwini. Ngaxa lithile, phantse wonke umntu uqala ukujonga iindlela ukwazi umzimba. Ngokomzekelo, abanye bachitha imali enkulu kuzo zonke iintlobo zobugcisa anti-ukwaluphala, abanye bafumane izithambiso cheap, abanye bafuna uncedo amayeza emveli kunye njalo njalo.

Andifuni ukuba ukudanisa nabani na, kodwa namhlanje akukho zomlingo izithambiso, iipilisi, okanye ezinye iindlela ezinokuthi ukubuyela 100% mfana basekhaya angaphandle. Nangona ukuba kucaphuka, ngenxa yokuba ngoku kukho iindlela kukwaluphala. Bakwazi ukuphucula kakhulu urhulumente omzimba womntu, ukongeza, ukuphucula izinga lokuphila kwakhe. Ndifuna ukuqaqambisa enye yezi ndlela - lo lobomi iiseli stem (kokubini ngaphambi nasemva iifoto ingabonwa kweli nqaku).

Ngaphandle kokuba le ndlela musani ukubamba isithembiso umzimba omtsha womntu nyaka-amabini, ingakumbi ukuba wena 50, ekuvuseleleni oko umzimba, umzimba oneminyaka engama-50 ubudala uya kujonga 40 ubuninzi, kuya kuba lula ukuba ukumelana iintlobo zosulelo, uya kufumana imikhosi isigxina zempilo kunye nokomelela.

uphando

Oosonzuluwazi kudala bathi iiseli babantu stem osandul zinako ukuba izihlunu naluphi uhlobo, okhoyo emzimbeni, kuphela utshintsho ukusuka theory practice kuye kwaba nzima. Phantsi kweemeko laboratory, oko isondlo kunokwenzeka ukuba zikhule ezi seli, kodwa kukho imiqobo enzima ukuya ingqiqo kwindlela yokuziphatha ngentsulungeko - kuba ezi nkqubo zifuna umbungu lokubulala.

Ngo-2007, i-ukufunyanwa yenziwa ukuba ezinye iiseli abadala bayakwazi ukubuyela imfundiso yabo ubuntwana. izifundo Ezinye lubonise ukuba indlela elula ukudala iiseli pluripotent eyabangelwa ayikho ngempumelelo xa Ngokusebenza kunye iiseli abadala, nto leyo iya kuba luncedo ngakumbi, nkqubo onjalo.

Lobomi kweeseli stem (kokubini ngaphambi nasemva iifoto aboniswe kweli nqaku) iye imiqobo zayo, phakathi apho iinkqubo zendalo zokusebenza ezinxulumene nokuguga kwaye ibangele ukufa kweeseli xa iindlela ezithile ngaphakathi kuzo kunxitywe kakhulu ukuba isebenze ngokupheleleyo. Emva kokufunda lo, izazinzulu ziye kusetyenziselwa ukwenza pluripotent eyabangelwa cell stem ukhutshelo factor 2 - LIN28 kunye NANOG.

imifuniselo

Kufuneka kuqatshelwe ukuba lobomi kunye iiseli esiqwini, abantu 74-101 basenokuthi ngezi imifuniselo. Iiseli aqokelelwa markers eziliqela ebalulekileyo ngokwaluphala, kuquka ubungakanani telomere - "oonobumba" ezincinane yokhuselo, apho ibekwe phezu eziphelweni zofuzo.

Telomere kunye Telomerase (nokulawula enzyme yabo) zezona zinto ziphambili obude kunye lobomi.

Iiseli telomere emva ngamnye banxibe division bit. Kulo mzekelo, lo msebenzi telomerase kukuba ukubuyisela kubo kancinane, kodwa kuza ixesha xa telomere ziguge; kwandule seli iyafa.

reprogramming iiseli

Lobomi stem cell ephilayo yindlela ezintsha reprogramming, nto leyo kwixa elizayo ukuze zisetyenziswe ukugqibezela lobomi. Kodwa izazinzulu zithi ukuba lo mzuzu kusekutsha kakhulu ukuba sichwayite ziqalise ukwenza izicwangciso ubomi bakho phambili kangangeminyaka eli-150.

Ukuhlolwa iimpuku lubonise ukuba ukusekwa iiseli stem abadala udibana iingxaki. Ngenxa yoko, ezinye iiseli pluripotent eyabangelwa kwamajoni omzimba eyahlukaniswekumazwe, nokuba yokuba zivela umzimba womntu, ke ngoko, kwi-experiments ukuba ukusetyenziswa liphela practice nangoku indlela ende ukuya.

Iimpawu lobomi

Njengoko kukhankanyiwe ngasentla, le lobomi yeziphumo cell isikhondo kodwa kube yeyona engalindelekanga. Kodwa nayiphi na imeko, ukuba ayibobuchule revolution leyo yahluke kakhulu kuzo zonke ezinye ezaziwayo ngaphambili.

Kanye njani lobomi? Izazinzulu zithi umzimba uyakhula omdala Unxiba waphuma ngenxa zingadinwa kuba igcina iiseli zawo stem. Kulo mzekelo, sithelekisa uhlalutyo ixhego, nomntwana, bafumanisa ukuba umzimba womntu amahlanu kakhulu ngaphantsi isiqu iiseli ngakumbi umzimba kosana, ngoko ukuba Ukongezelela ebiqaliswe kwi emzimbeni, ukusebenza kwawo onke amalungu kunye neenkqubo kufuneka nganye, nto leyo ithetha ukuba kwenzeke lobomi.

Buyela Life

Okwenziwayo kubalelwa ekunqandeni iiseli - a ukuvuselelwa, ngamanye amazwi, ukuvuselelwa ebomini, ukuvuselelwa. Ukuguga akukho onesiphene okanye kuphambuka, yinkqubo yendalo, ngokuthe ngcembe ziqala ukufiphala, yehlisa imisebenzi ethile, yaye oku kukhokhelela ekufuneni utshintsho imbonakalo yomntu. Kwaye ngoko ke imibimbi eluswini, ilahlekile luthambe. Kodwa le utshintsho yangaphandle kuphela. Kulo guga luchaphazela amalungu angaphakathi, kananjalo, kwaye kufuneka nabo ukuba ibuyekezwe. iiseli lobomi stem esilungiselelwe ngokuqinisa ulusu kunye mibimbi effacement, kwakunye kwakhona yonke eziphilayo.

ukuvuselelwa yesikhumba

cosmetology Medical ikuvumela ukuba balwe ngamxhelo mnye ubudala ngoncedo iiseli stem. Kukho kwakhona ingqikelelo 'umntu yokuhlaziywa ", ngamanye amazwi, lobomi yayo, kugxininiswa emxinwa engakumbi ukulungiswa iyonke. Ukuvuselelwa Local kwenza kube lula ukuba ngokulalisa Undintshwenyisile, buyisela ibala, buyisela ukuqina, umbala, ukhanye kunye luthambe, ukuphelisa hyperpigmentation - kubuya zonke iimpawu wentlonze oselula esempilweni. Kulo mzekelo, ngumongo impembelelo wengingqi kukuba ukusebenza iiseli stem kungena entsimini efanelekileyo, kulo mzekelo, waya isikhumba.

Izimo

Ukuthetha into lobomi yingozi weeseli stem, kufuneka kuthiwe Izimo ecacileyo iingcali musa, ukutyhila kungenzeka ngenxa ulwazi abaziintsizana inkqubo. Kodwa ngaphambi kokuba oogqirha nkqubo wenziwe uphando ukuchonga naluphi na utyeshelo kunokwenzeka.

Ekukholelwa ukuba lobomi iiseli stem ebangela umhlaza, kodwa kuyafuneka ukuba siyavuma ukuba ubungqina ngqo kule no. Ukungenisa kubo - oku ke unyango salon, ayikho indlela elula, yinto ngummandla cosmetology unyango, ngoko, oko kufuneka kwenziwe ngaphandle ekliniki olulodwa, nto leyo eye igama elihle. Xa ndandineminyaka enye, nto leyo ifanele ukuba le nkqubo - iminyaka 35-40.

isimiso ukusebenza

Xa abantu, iiseli stem bamele "matrix" ezinako senziwa similise a esikule naluphi na uhlobo. Ngoko ke, loo lobomi uthathwa ngokuba unzima, esisebenza kuzo zonke organ kunye yonke inkqubo yomzimba womntu. Kuye angqiniweyo ngokwezenzululwazi. iiseli lobomi stem ngokubonakalayo kwaphucula imo izintso, intliziyo, isikhumba, isisu, emathunjini, isibindi, yomqolo, njalo njalo.

Igalelo esikhumbeni

Lobomi kweeseli elisisiqu imbonakalo ngendlela eyiyo yaye ngokukhawuleza ukuba loo mntu ngokwakhe akukhangela esipilini, kaninzi akakholwa amehlo akhe. Ulusu abangcono kakhulu:

• ukushiya amabala kunye cyanosis;
• imibimbi ukuba Walungisa;
• unokukhawuleza isikhumba ngokuyinqaba kwaye njalo njalo.

Ukuba lobomi onjalo, umntu lithi libe negalelo entsha, ocwengileyo kulutsha apho emehlweni akhe.

nokukhethwa ekliniki

Okwangoku Okwangoku kukho inani elikhulu amaziko zonyango ukuba basebenze ngale ndlela. Iiklinikhi abanabasebenzi lobomi kunye iiseli stem - oko kusoloko liziko eqinisekisiweyo. Nangona inkoliso yabo yenza nogxininiso ekuveliseni iziphumo zonyango kule nqubo. Kunye namaziko nje ezimbalwa ingabizwa iikliniki lobomi lokwenyaniso. Benza kugxininiswa kwiseli abohlukeneyo ekhethekileyo.

Kufuneka kuqatshelwe ukuba le arhente isithuba post-eSoviet, ngexesha elifanayo sisebenzayo unyango kunye lobomi umntu, omnye. Kuzo ukuba isicelo. Bona lonke eqalisa izinto ezintsha nobuchwepheshe, zonke unyaka kokuziqhelanisa unyango kunye lobomi iiklayenti zazo. Xa impilo ekliniki enjalo, ubuhle kunye nolutsha zikwinqanaba elifanayo. Ukongezelela, ukukhetha iziko, musa ukuthandabuza ukuba ukucela zizatifikethi nkqubo, ukongeza, funda malunga izikhuselo inika kubaxumi bayo. Kulo mzekelo, kuya kuba ngcono ukuba ukubuza malunga neziphumo izigulane lokwenene.
