Ososayensi baseJapan ngenxa yokucwaninga kwaba yindlela entsha, okuvumela ukudala inyama yenkomo yenkomo yokufakelwa kusetshenziswa amaseli we-stem. Izinto ezivelayo azihlukile ezimfanelweni eziphambili ezivela kwemvelo, futhi zinezinzuzo eziningi.
Esezinhlelweni zomsebenzi wayo wesayensi, ama-biotechnologists amele iTokyo University (Japan) adale i-analogue yobuchwepheshe esetshenziswa ongoti emthini wokuvuselela kabusha futhi avuselele imisipha. Ukuze uqhathanise, odokotela ngaleyo ndlela baphinda bahlambalaze izicubu zomzimba ezilahlekile ngokukhulisa izingqimba ezicijile zemicu yamaseli abo, zibabeke komunye nomunye ngendlela ekhethekile. Ukuhlola i-hypothesis yokuqala, inhloko yokufunda iSydy Taketo nozakwabo balungiselela ozimele abaningana abadalwe kusuka ku-hydrogel nase-polymers, kufana kakhulu esakhiweni sabo kube yisisekelo semicibisholo yemisipha. Lapho-ke izinhlaka zozimele zedatha zifakwe ngamaseli we-stem, kwavuselela "ukwakhiwa" ngemivimbo kagesi futhi ekugcineni kwaqoqwa kusuka kuyo i-analogue yezicubu zemisipha yenkomo. Umphumela waba yizingcezwana zenyama ezibukeka enengqondo, enendawo ecishe ibe ngu-1 cm2 kanye nobukhulu bamamilimitha ambalwa. Iphuzu eliyinhloko lelo kwakuyiqiniso ukuthi inyama ephumela, yoshizi futhi ethosiwe, ukuze atholwe amandla, ukuze anikeze amandla, ukwakheka, ukupenda nezinye izakhiwo, akuhlukile kwezemvelo.
Kuyaphawuleka ukuthi amasampula okuqala emhlabeni wozakwabo benyama yokufakelwa kochwepheshe baseJapan adale eminye imininingwane eyisikhombisa eyedlule, kodwa izindleko zayo zamanje ezingeni lamadola angaphezu kwenkulungwane ka-US Lilogram kubhekwa njengenzuzo ngokuphelele. Ngaphezu kwalokho, ukwaziswa okunjalo, ngokusho kochwepheshe, akukhangi ukunambitha, futhi kufana noketshezi olunamanzi, hhayi izicubu. Njengoba abacwaningi bachaza, isizathu salokhu ukwakheka okungeyona okwemvelo kwenyama ekhule kuphela kumaseli we-stem, kanye nokungabikho kwesethi ephelele yamaseli angohlobo lwenkomo yangempela noma ingulube kule micu yangempela.
By the way, abathuthukisi baseJapan basho ukuthi izinto ezintsha zokuthola inyama etholakele azange ziqukathe amagciwane ngokwalo, okuhlukanisa kusuka kwinkomo yangempela. Lokhu kumvumela ukuthi aqhubeke isikhathi eside futhi anika amandla, njengoba ososayensi bethemba, ukuheha okukhethekile kwabathengi abangaba khona. Izinto zokwenziwa zesayensi zashicilelwa kwisayensi yokudla.
