Abstract
Enamel tissue, the hardest body tissue, which covers the outside of the tooth shields the living tissue, but it erodes and disintegrates in the acidic environment of the oral cavity. On the one hand, mature enamel is cell-free and, if damaged, does not regenerate. Tooth sensitivity and decay are caused by enamel loss. On the other hand, the tissue engineering approach is challenging because of the unique structure of tooth enamel. To develop an exemplary method for dental enamel rebuilding, accurate knowledge of the structure of tooth enamel, knowing how it is created and how proteins interact in its structure, is critical. Furthermore, novel techniques in tissue engineering for using stem cells to develop enamel must be established. This article aims to discuss current attempts to regenerate enamel using synthetic materials methods, recent advances in enamel tissue engineering, and the prospects of enamel biomimetics to find unique insights into future possibilities for repairing enamel tissue, perhaps the most fascinating of all tooth tissues.

Biological characteristics of dental pulp stem cells and their potential use in regenerative medicine. J Oral Biosci 2022; 64:26-36.

Abstract
BACKGROUND Regenerative medicine has emerged as a multidisciplinary field with the promising potential of renewing tissues and organs. The main types of adult stem cells used in clinical trials are hematopoietic and mesenchymal stem cells (MSCs). Stem cells are defined as self-renewing clonogenic progenitor cells that can generate one or more types of specialized cells. HIGHLIGHT MSCs form adipose, cartilage, and bone tissue. Their protective and regenerative effects, such as mitogenic, anti-apoptotic, anti-inflammatory, and angiogenic effects, are mediated through paracrine and endocrine mechanisms. Dental pulp is a valuable source of stem cells because the collection of dental pulp for stem cell isolation is non-invasive, in contrast to conventional sources, such as bone marrow and adipose tissue. Teeth are an excellent source of dental pulp stem cells (DPSCs) for therapeutic procedures and they can be easily obtained after tooth extraction or the shedding of deciduous teeth. Thus, there is increased interest in optimizing and establishing standard procedures for obtaining DPSCs; preserving well-defined DPSC cultures for specific applications; and increasing the efficiency, reproducibility, and safety of the clinical use of DPSCs. CONCLUSION This review comprehensively describes the biological characteristics and origins of DPSCs, their identification and harvesting, key aspects related to their characterization, their multilineage differentiation potential, current clinical applications, and their potential use in regenerative medicine for future dental and medical applications.

Differentiation of dental pulp stem cells into neuron-like cells in serum-free medium. Stem Cells Int 2013; 2013:250740.

Abstract
Dental pulp tissue contains dental pulp stem cells (DPSCs). Dental pulp cells (also known as dental pulp-derived mesenchymal stem cells) are capable of differentiating into multilineage cells including neuron-like cells. The aim of this study was to examine the capability of DPSCs to differentiate into neuron-like cells without using any reagents or growth factors. DPSCs were isolated from teeth extracted from 6- to 8-week-old mice and maintained in complete medium. The cells from the fourth passage were induced to differentiate by culturing in medium without serum or growth factors. RT-PCR molecular analysis showed characteristics of Cd146(+) , Cd166(+) , and Cd31(-) in DPSCs, indicating that these cells are mesenchymal stem cells rather than hematopoietic stem cells. After 5 days of neuronal differentiation, the cells showed neuron-like morphological changes and expressed MAP2 protein. The activation of Nestin was observed at low level prior to differentiation and increased after 5 days of culture in differentiation medium, whereas Tub3 was activated only after 5 days of neuronal differentiation. The proliferation of the differentiated cells decreased in comparison to that of the control cells. Dental pulp stem cells are induced to differentiate into neuron-like cells when cultured in serum- and growth factor-free medium.

Abstract
Differences between pulp repair and regeneration guide different strategic options. After mild carious dentin lesions, odontoblasts and Hoehl’s cells are implicated in the formation of reactionary dentin. Reparative dentin formation and/or pulp regeneration after partial degradation is under the control of pulp progenitors. A series of questions arise from recent researches on tissue engineering. In this series of questions, we compare the therapeutic potential of pluripotent embryonic and adult stem cells, both being used in cell-based dental therapies. Crucial questions arise on the origin of stem cells and the localization of niches of progenitors in adult teeth. Circulating progenitor cells may also be candidate for promoting pulp regeneration. Then, we focus on strategies allowing efficient progenitors recruitment. Along this line, we compare the potential of embryonic stem cells versus adult stem cells. Re-programming adult pulp cells to become induced pluripotent stem cells constitute another option. Genes, transcription factors and growth factors may be used to stimulate the differentiation cascade. Extracellular matrix molecules or some bioactive specific domains after enzymatic cleavage may also contribute to the formation of an artificial pulp and ultimately to its mineralization.

Abstract
Adult stem cells are multipotent and can be induced experimentally to differentiate into various cell lineages. Such cells are therefore a key part of achieving the promise of tissue regeneration. The most studied stem cells are those of the hematopoietic and mesenchymal lineages. Recently, mesenchymal stem cells were demonstrated in dental tissues, including dental pulp, periodontal ligament, and dental follicle. The dental follicle is a loose connective tissue that surrounds the developing tooth. Dental follicle stem cells could therefore be a cell source for mesenchymal stem cells. Indeed, dental follicle is present in impacted teeth, which are commonly extracted and disposed of as medical waste in dental practice. Dental follicle stem cells can be isolated and grown under defined tissue culture conditions, and recent characterization of these stem cells has increased their potential for use in tissue engineering applications, including periodontal and bone regeneration. This review describes current knowledge and recent developments in dental follicle stem cells and their application.

Abstract
Recently, the possibility of tooth tissue engineering has been reported. Although there are a number of available materials, information about scaffolds for tooth tissue engineering is still limited. To improve the manageability of tooth tissue engineering, the effect of scaffolds on in vivo tooth regeneration was evaluated. Collagen and fibrin were selected for this study based on the biocompatibility to dental papilla-derived cells and the results were compared with those of polyglycolic acid (PGA) fiber and beta-tricalcium phosphate (beta-TCP) porous block, which are commonly used for tooth, dentin and bone tissue engineering. Isolated porcine tooth germ-derived cells were seeded onto one of those scaffolds and transplanted to the back of nude mice. Tooth bud-like structures were observed more frequently in collagen and fibrin gels than on PGA or beta-TCP, while the amount of hard tissue formation was less. The results showed that collagen and fibrin gel support the initial regeneration process of tooth buds possibly due to their ability to support the growth of epithelial and mesenchymal cells. On the other hand, maturation of tooth buds was difficult in fibrin and collagen gels, which may require other factors.
