Area of Science:

  • Oral biology
  • Stem cell research
  • Regenerative medicine

Background:

  • Teeth and supporting tissues offer accessible oral stem cells with high plasticity and differentiation potential.
  • Dental pulp, apical papilla, periodontal ligament, and gingival tissues are sources of various stem cell populations.
  • Oral mucosa exhibits remarkable scarless wound healing, involving epithelial, mesenchymal, and immune cells.

Purpose of the Study:

  • To review current knowledge on diverse oral stem cells.
  • To highlight novel approaches for studying oral stem cell populations and their niches.
  • To explore the potential of oral stem cells in tissue engineering and therapeutics.

Main Methods:

  • Utilizing continuously growing mouse incisor models for in vivo studies of dental pulp stem cells.
  • Employing single-cell RNA-sequencing and cell-tracing techniques.
  • Mapping resident cell populations within diverse oral tissues.

Main Results:

  • Oral stem cells, previously considered homogeneous, are revealed as diverse populations.
  • A highly organized map of cell populations and their niches within oral tissues has been elucidated.
  • New approaches decode and map resident cell populations, enhancing understanding of stem cell niche architecture and interactions.

Conclusions:

  • Diverse oral stem cells possess significant potential for tissue engineering and therapeutic applications.
  • Understanding stem cell niche architecture and interactions is crucial for developing innovative solutions.
  • The accessibility and properties of oral stem cells support their translational potential.
