Overview of Exosomes01:36

Overview of Exosomes

Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...
Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their access...
Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Area of Science:

  • Biomaterials Science
  • Regenerative Medicine
  • Oral Biology

Background:

  • Regenerative dentistry is transitioning from cell-based therapies to cell-free biologics for tissue repair.
  • Exosomes, nanoscale vesicles with bioactive payloads, are key regulators of intercellular communication.
  • This review synthesizes exosome applications in oral and craniomaxillofacial (CMF) tissue regeneration.

Purpose of the Study:

  • To provide a comprehensive overview of exosome-based regenerative strategies in dentistry.
  • To explore the mechanisms and signaling pathways involved in exosome-mediated tissue repair.
  • To discuss bioengineering approaches enhancing exosome efficacy for clinical translation.

Main Methods:

  • A systematic literature review was conducted using major scientific databases (PubMed, Scopus, Web of Science).
  • Included studies encompassed in vitro, in vivo, and clinical research on exosome mechanisms and applications.
  • Focus was placed on molecular signaling, bioengineering, and regenerative outcomes in dental and CMF tissues.

Main Results:

  • Exosomes from various cell sources demonstrated potent regenerative effects in periodontal, endodontic, orthodontic, and CMF applications.
  • Key mechanisms included promoting osteogenesis, angiogenesis, immune modulation, and stem cell recruitment via pathways like PI3K/AKT and Wnt/β-catenin.
  • Bioengineering strategies significantly improved exosome stability, targeting, and therapeutic efficacy.

Conclusions:

  • Exosomes offer a versatile, cell-free therapeutic platform for complex oral tissue regeneration.
  • Preclinical data highlight the potential of exosomes in enhancing cell viability, differentiation, and tissue homeostasis.
  • Standardization, scalability, and clinical validation are crucial for integrating exosome therapy into dental practice.
