Overview of Exosomes01:36

Overview of Exosomes

2.9K
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...

Clinical Applications of Epidermal Stem Cells

2.8K
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...

Area of Science:

  • Dermatology
  • Regenerative Medicine
  • Aesthetics

Background:

  • Exosomes play key roles in dermatology, including wound healing, cell migration, extracellular matrix reconstruction, and angiogenesis.
  • Their therapeutic potential is being explored for various dermatological applications.

Purpose of the Study:

  • To review existing literature on the use of exosomes for skin rejuvenation.
  • To review existing literature on the use of exosomes for hair regeneration.

Main Methods:

  • A comprehensive literature search was conducted using the PubMed database.
  • Studies published up to October 2021 were included in the review.

Main Results:

  • Preclinical studies indicate exosomes promote skin rejuvenation and hair growth in vitro and in animal models.
  • Currently, only one clinical study has been published, and no exosome-based products are FDA-approved for these applications.

Conclusions:

  • Exosomes demonstrate potential in preclinical aesthetic research for skin and hair regeneration.
  • Significant hurdles remain in exosome purification, isolation, storage, scalability, and reproducibility for clinical use.
