Cell Homing Strategies in Regenerative Endodontic Therapy.

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Endodontics

Background:

• Cell homing leverages endogenous stem/progenitor cells for tissue repair, offering an alternative to transplantation.
• Stem cells from apical papilla, bone marrow, and periapical tissues are key targets for recruitment.
• Chemotactic biological cues are essential for directing cell migration to damaged sites.

Purpose of the Study:

• To review in vivo animal studies on cell homing strategies for dental pulp regeneration.
• To explore the role of biomolecules and scaffold materials in recruiting endogenous stem cells.
• To examine advancements and limitations of cell homing in regenerative endodontic therapy.

Main Methods:

• Analysis of in vivo animal studies employing cell homing strategies.
• Evaluation of biomaterial scaffolds and signaling molecules for enhancing cell recruitment.
• Review of principles, advancements, and limitations in cell homing-based regenerative endodontics.

Main Results:

• Biomolecules and scaffold materials effectively enhance endogenous stem cell recruitment to damaged dental pulp.
• Cell homing strategies promote cell migration, adhesion, and differentiation for pulp-dentin complex regeneration.
• Successful application of cell homing in promoting repair of dental pulp tissue was observed in animal models.

Conclusions:

• Cell homing is a viable strategy for regenerative endodontic therapy, utilizing endogenous stem cells.
• The interplay between biomaterials and signaling molecules is crucial for successful cell homing and tissue regeneration.
• Further research into current limitations can optimize cell homing for clinical applications in endodontics.
