Peptides ka kooban 8 ku celis ah aspartate-serine-serine (8DSS) ayaa la muujiyay in ay kor u nukleation of fosfat calcium ka xal galay dhaldhalaalka aadanaha.Halkan waxaan ku tijaabinay awoodda 8DSS si ay kor ugu qaaddo dib-u-soo-noolaynta dhaldhalaalka demineralized ee qaabka in vitro ee suus dhaldhalaalka hore ee macmalka ah.Nabarada suuska bilawga ah ayaa lagu abuuray baloogyada dhaldhalaalka bovine, kuwaas oo markaa lagu sakhiray 12 d ee baaskiil wadista pH iyadoo ay joogaan 25 µM 8DSS, 1 g/L NaF (xakamaynta togan) ama kaligiis (xakamaynta xun).Nuugista 8DSS waxaa lagu xaqiijiyay raajada sawir-qaadista sawir-qaadista.Luminta macdanta, qoto-dheeraanta dhaawaca, iyo nuxurka macdanta ee lakabka dusha sare iyo moolka kala duwan ee jidhka nabarka ayaa lagu falanqeeyay kahor iyo ka dib baaskiilka pH by microscopy iftiin leh iyo microradiography transverse.Luminta macdanta ka dib baaskiilka pH ayaa si aad ah uga hooseeya muunadaha 8DSS marka loo eego muunadaha kaydka-keliya, iyo nabarada muunadaha 8DSS aad bay u qotonayeen.Tijaabooyin lagu daweeyay 8DSS waxay muujiyeen macdan aad uga sarreeya muunado-kaliya ee gobolka ka soo baxa lakabka sare (30 µm) ilaa celceliska qoto dheer ee dhaawaca (110 µm).Ma jiro farqi weyn oo u dhexeeya shaybaarrada lagu daweeyay 8DSS iyo kuwa lagu daweeyay NaF.Natiijooyinkani waxay soo jeedinayaan in 8DSS ay awood u leedahay inay kor u qaaddo dib-u-soo-celinta dhaldhalaalka la dejiyay.
