Insights

Mesenchymal stem/stromal cells (MSCs) use microRNAs (miRNAs) to reduce inflammation. This review highlights validated miRNAs involved in MSCs' anti-inflammatory effects for potential therapeutic applications.

Area of Science:

  • Regenerative Medicine
  • Immunology
  • Molecular Biology

Background:

  • Mesenchymal stem/stromal cells (MSCs) are progenitor cells found in various adult and placental tissues.
  • MSCs possess pleiotropic functions, making them promising for treating degenerative and inflammatory diseases.
  • Their therapeutic effects are primarily mediated by secreted trophic factors, including extracellular vesicles containing proteins, lipids, mRNAs, and miRNAs.

Purpose of the Study:

  • To review and summarize the current data on microRNAs (miRNAs) that have been validated as key contributors to the anti-inflammatory function of MSCs.
  • To highlight the specific miRNAs involved in MSC-mediated immunomodulation.
  • To provide insights into the therapeutic potential of MSC-derived miRNAs in inflammatory conditions.

Main Methods:

  • Literature review of scientific publications.
  • Analysis of studies validating the role of specific miRNAs in MSC immunomodulatory functions.
  • Synthesis of data on miRNA mechanisms and effects on immune cells.

Main Results:

  • Several miRNAs have been identified and validated for their role in the anti-inflammatory capacity of MSCs.
  • These miRNAs contribute to MSCs' immunomodulatory effects through various mechanisms.
  • The specific anti-inflammatory actions of these miRNAs are detailed, offering a molecular basis for MSC therapies.

Conclusions:

  • MicroRNAs are crucial mediators of the anti-inflammatory properties of mesenchymal stem/stromal cells.
  • Understanding these miRNA-mediated mechanisms can advance the development of novel cell-based and cell-free therapies for inflammatory diseases.
  • Further research into MSC-derived miRNAs holds significant promise for regenerative medicine and immunotherapy.

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...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Adult Stem Cells01:33

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Embryonic Stem Cells

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Binet's Contribution to Measures of Intelligence

Alfred Binet, along with his student Théophile Simon, was tasked by the French Ministry of Education in 1904 to create a method for identifying students who struggled to learn through conventional classroom instruction. This initiative aimed to address overcrowding by placing such students in specialized schools. Binet and Simon developed an intelligence test comprising 30 tasks, ranging from simple commands, like touching one's nose or ear, to more complex tasks, such as drawing...
