Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

4.6K
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...

Overview of Exosomes

2.7K
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...

Embryonic Stem Cells00:57

Embryonic Stem Cells

3.4K
Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Area of Science:

  • Biomedical Science
  • Regenerative Medicine
  • Cell Biology

Background:

  • Stem cell therapy shows promise for intractable diseases but faces challenges like tumorigenicity and immune rejection.
  • Extracellular vesicles (EVs) from stem cells can deliver therapeutic cargo with lower immunogenicity.
  • Mesenchymal stem cell (MSC)-derived EVs are gaining attention for their therapeutic potential.

Purpose of the Study:

  • To review the advances in using extracellular vesicles derived from mesenchymal stem cells (MSC-EVs) for clinical applications.
  • To highlight the therapeutic benefits and applications of MSC-EVs in various disease models.

Main Methods:

  • Literature review summarizing current research on MSC-EVs.
  • Analysis of studies investigating MSC-EVs in inflammatory, tissue repair, cancer, and neurodegenerative disease contexts.

Main Results:

  • MSC-EVs are effective in treating inflammatory conditions like rheumatoid arthritis, liver injury, COVID-19, and allergies.
  • MSC-EVs promote tissue repair in cardiovascular, kidney, and osteoarthritic diseases.
  • MSC-EVs function as drug carriers for cancer therapy and regenerative agents for neurodegenerative disorders like Alzheimer's and Parkinson's.

Conclusions:

  • MSC-EVs represent a promising cell-free therapeutic strategy, overcoming limitations of direct stem cell transplantation.
  • The low immunogenicity and targeted delivery of MSC-EVs make them a versatile tool in regenerative medicine and disease treatment.
