Lolani Ikule: Khungu lopangidwa ndi lab tsopano likhoza kutulutsa tsitsi lake ndi zotupa za thukuta

Ngati mumadikirira khungu lokulitsa labu kuti lizitha kumera tsitsi ngati Chia Pet, ino ndi nthawi yokondwerera. Gulu la ofufuza a ku Tokyo University of Science apanga chiwopsezo chachikulu chachipatala kuti khungu lomera labu likhale logwirizana kwambiri ndi momwe khungu lachilengedwe limachitira.

Izi zisanachitike, khungu lopangidwa ndi labu linkangokongoletsa kokha kwa odwala olumikizidwa pakhungu, koma "khungu" linalibe magwiridwe antchito kapena kulumikizana ndi minofu yozungulira. Njira yatsopanoyi yakukulira khungu ndikugwiritsa ntchito ma cell tsinde, komabe, tsopano imalola osati tsitsi lokha, komanso mafuta otulutsa sebaceous glands ndi thukuta kukula.

Zotsatira Zawo

Motsogozedwa ndi Ryoji Takagi, ofufuza aku Japan adagwira ntchito ndi mbewa zopanda tsitsi zoponderezedwa ngati maphunziro. Mwa kukanda m'kamwa mwa mbewa kuti atenge zitsanzo za minofu, ofufuza adatha kusintha zitsanzozo kukhala maselo opangidwa ndi injini, otchedwa induced pluripotent cell (maselo a IPS); ma cellwa adayamwitsidwa ndi chizindikiro chamankhwala chomwe chingawapangitse kuti ayambe kutulutsa khungu. Pambuyo pa masiku angapo akumera mu labu, zitsitsi zatsitsi ndi tiziwalo timene timatulutsa timayamba kuoneka.
