Vnit\u0159n\u00ed bun\u011b\u010dn\u00e1 hmota obsahuje pluripotentn\u00ed kmenov\u00e9 bu\u0148ky, kter\u00e9 jsou z n\u00ed izolov\u00e1ny a kultivov\u00e1ny. Kmenov\u00e9 bu\u0148ky lze nal\u00e9zt tak\u00e9 v diferencovan\u00fdch tk\u00e1n\u00edch i org\u00e1nech v cel\u00e9m t\u011ble. <\/p>\n\n\n\n

Dosp\u011bl\u00e9 kmenov\u00e9 bu\u0148ky jsou extrahov\u00e1ny ze vzork\u016f tk\u00e1n\u00ed a bu\u0148ky jsou suspendov\u00e1ny v kapalin\u00e1ch a pot\u00e9 separov\u00e1ny podle povrchov\u00fdch marker\u016f bun\u011bk pomoc\u00ed fluorescen\u010dn\u011b aktivovan\u00e9ho t\u0159\u00edd\u011bn\u00ed bun\u011bk (FACS). Pupe\u010dn\u00edk novorozence obsahuje tak\u00e9 krevn\u00ed kmenov\u00e9 bu\u0148ky. Ty se obvykle rekonstituuj\u00ed a skladuj\u00ed, aby mohly b\u00fdt pozd\u011bji pou\u017eity ve prosp\u011bch v\u00fdzkumu nebo jako pomoc p\u0159i budouc\u00ed l\u00e9\u010db\u011b, kterou m\u016f\u017ee d\u00e1rce pot\u0159ebovat. Plodov\u00e1 voda je skv\u011bl\u00fdm zdrojem kmenov\u00fdch bun\u011bk, kter\u00e9 jsou multipotentn\u00ed a obvykle trvanliv\u011bj\u0161\u00ed ne\u017e kmenov\u00e9 bu\u0148ky z\u00edskan\u00e9 jin\u00fdmi metodami.

Indukovan\u00e9 pluripotentn\u00ed bu\u0148ky vznikaj\u00ed ze somatick\u00fdch (dosp\u011bl\u00fdch nederminovan\u00fdch) bun\u011bk, kter\u00e9 jsou navr\u00e1ceny do stavu podobn\u00e9ho embryon\u00e1ln\u00edm kmenov\u00fdm bu\u0148k\u00e1m. Stejn\u011b jako embryon\u00e1ln\u00ed kmenov\u00e9 bu\u0148ky jsou iPS bu\u0148ky schopny diferenciace na jak\u00fdkoli typ bun\u011bk v t\u011ble, a proto jsou pova\u017eov\u00e1ny za pluripotentn\u00ed. Postup generov\u00e1n\u00ed t\u011bchto bun\u011bk, kter\u00fd se \u010dasto naz\u00fdv\u00e1 „p\u0159eprogramov\u00e1n\u00ed“, zahrnuje zaveden\u00ed kombinace se t\u0159emi nebo \u010dty\u0159mi r\u016fzn\u00fdmi geny, kter\u00e9 jsou transkrip\u010dn\u00edmi faktory, je\u017e jsou do bu\u0148ky vpraveny prost\u0159ednictv\u00edm retrovir\u016f. <\/p>\n\n\n\n

Bu\u0148ky lze z\u00edskat od pacient\u016f trp\u00edc\u00edch ur\u010dit\u00fdmi chorobami, jako je Parkinsonova choroba, ALS nebo kardiovaskul\u00e1rn\u00ed onemocn\u011bn\u00ed, a pot\u00e9 je p\u0159eprogramovat tak, aby vznikly bu\u0148ky iPS. Po diferenciaci na specializovan\u00e9 bu\u0148ky lze iPS bu\u0148ky vyu\u017e\u00edt k mnoha \u00fa\u010del\u016fm, nap\u0159\u00edklad k vytvo\u0159en\u00ed test\u016f pro studium procesu onemocn\u011bn\u00ed, k anal\u00fdze kandid\u00e1t\u016f na l\u00e9ky z hlediska bezpe\u010dnosti a \u00fa\u010dinnosti a k pou\u017eit\u00ed v regenerativn\u00ed medic\u00edn\u011b. <\/p>\n\n\n\n
