Background: Obtaining cells from the patient, expanding cell population on a scaffold, and, eventually, grafting the tissue to the patient is one of the tissue engineering techniques to create replacement tissue structures. Blastema tissue is one of the cellular sources in this regard. This study investigated the use of human gum tissue to prepare a scaffold and the interaction between the three-dimensional tissue scaffold and blastema tissue. Materials and Methods: In this experimental study, human gingiva was prepared and through snap freezing method and the use of sodium dodecyl sulfate (SDS) and Triton X-100, went through cell bleaching. Then the provided scaffoldings were placed in 2-day-old blastema rings and stored in culture media for 25 days. Sampling of the blastema and scaffolding tissues was done once every five days. Results: The results confirmed the removal of the cells from the prepared scaffolds. Also, histological studies in the fifth and tenth days indicated cell penetration into the blastema scaffolds. In the fifteenth day, in addition to penetration, blastema cells division and differentiation as well as epidermis genesis were observed. In the twentieth and twenty-fifth days, infiltration, cell division, and differentiation processes continued. Conclusion: The findings of this study indicated the possibility of creating a natural scaffold of human gingiva through this method. This scaffold can have an inductive effect on cell behaviors such as such as migration, adhesion, division, and probable differentiation. However, further studies for demonstrating the identity of the cells and other properties of such a scaffold as well as the possibility of using it in gingiva tissue engineering are recommended.
