The pinnacle of biomedical research is the ongoing development of cancer medicines. The strong therapeutic potential exists when the immune system is targeted and biological processes are used to enhance the body’s response to cancer. Mesenchymal stem cells (MSCs) are a particular kind of cell that may develop into several types of tissue and play a part in tissue regeneration and repair.
Mesenchymal stem cells also have immunomodulatory properties, which are attracting a lot of interest as a prospective strategy for the development of cell and gene treatments. For instance, based on what is necessary for tissue repair, MSCs can control the inflammatory and immunological response in the body by triggering specific immune cells.
Mesenchymal stem cells, as a biological tool, have two edges. The cells can help the body during tissue regeneration, but they can also cause cancers by supporting tumour microenvironments, promoting tumour growth, and inhibiting antitumor immune reactions. Knowing the mechanisms and interactions of mesenchymal stem cells in cancer is essential for creating potent treatments because of their pleiotropic nature.
How do MSCs Communicate?
Mesenchymal stem cells require intercellular communication to carry out their regulatory function. Through the use of proteins including cytokines, chemokines, and growth factors for signalling, mesenchymal stem cells can either profoundly change the microenvironment or indirectly. By releasing extracellular vesicles, mesenchymal stem cells can also affect how the microenvironment behaves.
Extracellular vesicles (EVs) have gained increased attention in recent years from the scientific and medical communities as important mediators in MSC cell-to-cell communication. EVs are made up of a variety of components, including proteins and RNA, which can affect how cells behave biologically. Extracellular vesicles generated by mesenchymal stem cells contain molecules that can either suppress or stimulate tumour growth. For example, some microRNAs have tumour-suppressive properties, while others, such as tissue inhibitors of metalloproteases (TIMP)-1 and -2, do the opposite. As a result, the mesenchymal stem cell communication pathway is a promising target for cancer therapy and may open up previously unravelling paths for treating disease.
Cancer Stem Cells and Mesenchymal Stem Cells
Extracellular vesicles produced by mesenchymal stem cells are an important component of the tumour microenvironment because they can be used by cancer stem cells and tumour cells to interact and cause modifications to the function of other cells. For instance, when MSCs enter a tumour, they can influence the movement of cancer cells by promoting the epithelial-mesenchymal transition process, which is where cells acquire the intrusive and transient traits that are frequently seen in metastatic cancers, a more severe and dangerous form of the disease. A more accurate representation of the tumour microenvironment can be created by researchers studying the interactions between mesenchymal stem cells and cancer stem cells using 3D cell cultures, commonly known as tumorspheres, which may provide extremely helpful discoveries into cancer biology.
The impact of cell therapy and gene therapy options can be increased, they can be improved, and alternative routes can be developed with a fuller understanding of the basic mechanisms underlying cancer.
