Mano amakula kudzera munjira zovuta momwe minofu yofewa, yolumikizira, mitsempha ndi mitsempha yam'magazi, yolumikizidwa ndi mitundu itatu yamatenda olimba kukhala gawo logwira ntchito. Monga chofotokozera cha njirayi, asayansi nthawi zambiri amagwiritsa ntchito mbewa yonyamula mbewa, yomwe imakula mosalekeza ndikusinthidwa m'moyo wonse wa nyama.

Ngakhale kuti mbewa zowononga mbewa nthawi zambiri zimawerengedwa m'njira yachitukuko, mafunso ofunikira ambiri okhudza ma cell amino osiyanasiyana, maselo am'magazi ndi kusiyanasiyana kwawo ndimphamvu zamagetsi sikuyenera kuyankhidwa.

Pogwiritsa ntchito njira imodzi yoyendetsera selo ya RNA ndi kutsata majini, ofufuza a Karolinska Institutet, Medical University of Vienna ku Austria ndi Harvard University ku USA tsopano azindikira ndikuzindikiritsa magulu onse am'mano a mbewa komanso mano achikulire omwe akukula komanso achikulire .

"Kuyambira pamaselo a tsinde mpaka kumaselo akulu akulu omwe tidawasiyanitsa tidatha kuzindikira njira zosiyanitsira ma odontoblast, zomwe zimapangitsa mano - zida zolimba zomwe zili pafupi kwambiri ndi zamkati - ndi ma ameloblast, omwe amatulutsa enamel," atero omaliza a kafukufukuyu wolemba Igor Adameyko ku department of Physiology and Pharmacology, Karolinska Institutet, komanso wolemba nawo Kaj Fried ku department of Neuroscience, Karolinska Institutet. "Tatulutsanso mitundu yatsopano yamaselo ndi ma selo m'mano omwe atha kugwira nawo gawo pakumva mano."

Zina mwazomwe zapezazi zitha kufotokozeranso zovuta zina za chitetezo cha mthupi m'mano, ndipo zina zimawunikiranso zatsopano za kapangidwe ka enamel wamano, mnofu wovuta kwambiri mthupi lathu.

"Tikukhulupirira ndikukhulupirira kuti ntchito yathu itha kukhala maziko a njira zatsopano zamankhwala opangira mawa mawa. Makamaka, zitha kufulumizitsa gawo lomwe likukula mwachangu la mano opatsirana, njira yothandizira pochotsa minyewa yowonongeka kapena yotayika. ”

Zotsatirazi zafotokozedwera pagulu ngati mawonekedwe osakira osavuta a mbewa ndi mano aanthu. Ofufuzawo amakhulupirira kuti ayenera kukhala othandiza osati kwa akatswiri a mano okha komanso kwa ofufuza omwe ali ndi chidwi chachitukuko komanso biology yatsopano.
