ABSTRACT Periodontal tissue supports teeth in the alveolar bone socket via fibrous attachment of periodontal ligament (PDL). The PDL contains fibroblasts and stem/progenitor cells, collectively known as cells (PDLCs), on top osteoblasts cementoblasts surface cementum, respectively. However, characteristics lineage hierarchy each cell type remain poorly defined. This study identified associated protein-1 (Plap-1) a PDL-specific extracellular matrix protein. We generated knock-in mice expressing CreERT2 GFP specifically Plap-1-positive PDLCs. Genetic tracing confirmed long-standing hypothesis that PDLCs differentiate into cementoblasts. A single-cell atlas defined Plap-1−Ibsp+Sparcl1+ Plap-1−Ibsp+Col11a2+, Other populations, such Nes+ mural S100B+ Schwann other non-stromal were also identified. RNA velocity analysis suggested Plap-1highLy6a+ population was source Lineage Plap-1+ during injury showed regeneration by Our defines diverse populations clarifies role homeostasis repair.

Periodontal tissue stem cells, which play a crucial role in maintaining the homeostasis of periodontal tissues, are found ligament (PDL). These cells have long been referred to as mesenchymal stem/stromal (MSCs), and their clinical applications extensively studied. However, PDL not thoroughly investigated, they may be different from MSCs. Recent advances cell biology, such genetic lineage tracing, identification label-retaining single-cell transcriptome analysis, made it possible analyze vivo. In this review, we summarize recent findings on these populations discuss future research directions toward developing regenerative therapy.

Abstract Soft tissue defects are a common clinical challenge mostly caused by trauma, congenital anomalies and oncological surgery. Current soft reconstruction options include synthetic materials (fillers implants) autologous adipose transplantation through flap surgery and/or lipotransfer. Both reconstructive hold important disadvantages to which vascularized engineering (VATE) strategies could offer solutions. In this review, we first summarized pivotal characteristics of functional such as the structure, function, cell types, development extracellular matrix (ECM). Next, discussed relevant sources how they applied in different state-of-the-art VATE techniques. Herein, biomaterial scaffolds hydrogels, ECMs, spheroids, organoids, sheets, three dimensional printing microfluidics overviewed. Also, included vesicles emphasized their potential role VATE.

Oral cavity stem cells (OCSCs) have been the focus of intense scientific efforts due to their accessibility and cell properties. The present work aims compare different characteristics 6 types dental derived from oral cavity: pulp (DPSC), human exfoliated deciduous teeth (SHED), periodontal ligament (PDLSC), apical papilla (SCAP), bone marrow mesenchymal (BMSC), gingival (GMSC). Using immunofluorescence real-time polymerase chain reaction techniques, we analysed for cell, differentiation, adhesion, extracellular matrix markers; ability proliferate in vitro; multilineage differentiation potential. Markers such as vimentin, CD44, alkaline phosphatase, CD146, CD271, CD49f, Oct 3/4, Sox 9, FGF7, nestin, BMP4 showed significant differences expression levels, highlighting heterogeneity unique each type. At same time, confirmed that all successfully differentiated into osteogenic, chondrogenic, or adipose lineages, with readiness. In conclusion, our study reveals distinct properties potential applications various dental-derived cells. These findings contribute a deeper understanding OCSCs significance future clinical applications.

Dental stem cells are heterogeneous in their properties. Despite common origin from neural crest cells, they have different functional capacities and biological functions due to niche influence. In this study, we assessed the differences between dental pulp (DPSC) periodontal ligament (PDLSC) pluripotency neuroepithelial markers transcription, morphological features, osteoblast/odontoblast differentiation proteomic profile during osteogenic differentiation.
