Abstract

Background: The study was designed to explore the enhanced impact of nano-hydroxyapatite and emdogain on the survival and osteogenic/odontogenic differentiation of human stem cells isolated from the apical papilla (hSCAPs).

Materials and methods: In this in vitro trial, hSCAPS obtained from intact impacted immature third molars were confirmed to have characteristic cell surface markers, then exposed to nanohydroxyapatite, emdogain, and nanohydroxyapatite coated with emdogain for durations of 1-3 days. The survival of apical papilla stem cells was measured using a methyl thiazolyl tetrazolium assay. The quantitative reverse transcription polymerase chain reaction, alkaline phosphatase activity (ALP) and Alizarin red staining were used to evaluate osteogenic-odontogenic differentiation. Analysis of the data was done using one-way ANOVA, t-test, and Mann-Whitney test (α = 0.05).

Results: At 1-3 days, emdogain exhibited no significant impact on the survival of human stem cells from the apical papilla. In contrast, nanohydroxyapatite (α > 0.05) and nanohydroxyapatite coated with emdogain demonstrated a notable reduction in cell survival compared to the control group (α < 0.05). The expression of dentin sialophosphoprotein, dentin matrix protein 1, and bone sialoprotein genes demonstrated a notable increase in the group treated with nanohydroxyapatite coated with emdogain compared to the other groups (α < 0.05), and furthermore, this group exhibited more pronounced mineralized nodules than the other experimental groups.

Conclusion: In contrast to nanohydroxyapatite, Emdogain did not demonstrate a detrimental effect on the survival of hSCAPs. Nanohydroxyapatite, emdogain, and nanohydroxyapatite coated with emdogain increased osteogenic/odontogenic differentiation of hSCAPs.

期刊介绍： Biotechnology Letters is the world’s leading rapid-publication primary journal dedicated to biotechnology as a whole – that is to topics relating to actual or potential applications of biological reactions affected by microbial, plant or animal cells and biocatalysts derived from them. All relevant aspects of molecular biology, genetics and cell biochemistry, of process and reactor design, of pre- and post-treatment steps, and of manufacturing or service operations are therefore included. Contributions from industrial and academic laboratories are equally welcome. We also welcome contributions covering biotechnological aspects of regenerative medicine and biomaterials and also cancer biotechnology. Criteria for the acceptance of papers relate to our aim of publishing useful and informative results that will be of value to other workers in related fields. The emphasis is very much on novelty and immediacy in order to justify rapid publication of authors’ results. It should be noted, however, that we do not normally publish papers (but this is not absolute) that deal with unidentified consortia of microorganisms (e.g. as in activated sludge) as these results may not be easily reproducible in other laboratories. Papers describing the isolation and identification of microorganisms are not regarded as appropriate but such information can be appended as supporting information to a paper. Papers dealing with simple process development are usually considered to lack sufficient novelty or interest to warrant publication.
