N\u00eb ndjekje t\u00eb ila\u00e7eve rigjeneruese, studiuesi kinez Toa Qin dhe koleg\u00ebt e tij u zhyt\u00ebn thell\u00eb n\u00eb mekanik\u00ebn prapa brir\u00ebve t\u00eb drer\u00ebve Sika, t\u00eb cilat riprodhohen \u00e7do vit para se t\u00eb bien.

Dhjet\u00eb dit\u00eb para se t\u00eb binin brir\u00ebt, studiuesit identifikuan nj\u00eb lloj qelize staminale q\u00eb ishte shum\u00eb aktive n\u00eb riprodhim, dhe k\u00ebto mbet\u00ebn me brir\u00ebt pak koh\u00eb pas derdhjes.

Pas identifikimit t\u00eb fazave t\u00eb shumta t\u00eb rritjes, ekipi mori qelizat burimore me potencialin m\u00eb t\u00eb ri t\u00eb rritjes (t\u00eb cilat u v\u00ebrtetuan se ishin nga brir\u00ebt e derdhur rreth pes\u00eb dit\u00ebsh) dhe i trajtuan n\u00eb nj\u00eb en\u00eb Petri p\u00ebrpara se t’i vendoste n\u00eb kok\u00ebn e minjve.<\/span><\/p>\n

Pas 45 dit\u00ebsh, minjt\u00eb kishin zhvilluar mini-brir\u00eb t\u00eb qart\u00eb t\u00eb identifikueshme, p\u00ebr shkak t\u00eb qelizave staminale q\u00eb diferencoheshin n\u00eb ind osteokondral, i cili \u00ebsht\u00eb integral n\u00eb riparimin e thyerjeve t\u00eb kockave.

Nj\u00eb trajtim i till\u00eb mund t\u00eb ngrej\u00eb shqet\u00ebsime etike n\u00eb lidhje me implantimin e qelizave nd\u00ebrspeciale, si dhe provat e r\u00ebnd\u00ebsishme t\u00eb siguris\u00eb q\u00eb do k\u00ebrkoheshin p\u00ebrpara se t\u00eb mund t\u00eb dor\u00ebzohej p\u00ebr miratim.
