Types of Mesenchymal Stem Cells (MSCs) and their Mechanisms of Action

Spread the love

Mesenchymal stem cells are the body’s raw materials — the cells that give rise to all other cells with specific roles. Adult stem cells with self-renewal, immunomodulatory, anti-inflammatory, signalling, and differentiation characteristics are known as mesenchymal stem cells. The ability of mesenchymal stem cells (MSCs) to divide and grow into numerous specialised cell types found in a particular tissue or organ is known as self renewal capability.

Adipose tissue (fat), bone marrow, umbilical cord tissue, blood, liver, tooth pulp, and skin are all good sources of mesenchymal stem cells (MSCs).

Adipose Tissue-Derived MSCs (ADSCs)

MSCs generated from adipose tissue (fat tissue) are taken from subcutaneous adipose tissue (fat tissue) and may be obtained in great numbers and with high cellular activity quickly using a liposuction technique.

When derived from a younger donor, ADSCs are more likely to be viable. This may be a problem for older individuals who undergo an autologous treatment (one in which your cells are used), since the older cells may be less suited to long-term survival in the recipient. When compared to older donors, adipose tissue-derived MSCs (ADSCs) have a greater proliferation rate (survivability after transplant), but their differentiation capability is maintained with age, giving them an advantage over bone marrow mesenchymal stem cells (BM-MSCs).

Bone Marrow-Derived MSCs (BM-MSCs)

Because of their self-renewable, differentiation, and immunomodulatory characteristics, bone marrow-derived mesenchymal stem cells (BM-MSCs), which are categorised as multipotent adult stem cells, are extensively utilised in the treatment of a variety of illnesses. In vitro and in vivo research has aided in the knowledge of the mechanisms, safety, and effectiveness of BM-MSC treatment in clinical settings. The number of phase I/II clinical studies is increasing, however they are restricted in terms of subject size, restrictions, and standards for the production, transportation, and administration of BMSCs, resulting in inconsistency in the therapy’s input and outcome.

Umbilical Cord Tissue-Derived Mesenchymal Stem Cells (UC-MSCs)

Wharton’s Jelly, cord lining, and the peri-vascular zone of the umbilical cord are all good places to look for UC-MSCs. The umbilical cord, being a frequently discarded tissue, provides a significant supply of mesenchymal stromal cells, which may be collected non-invasively.

What are the functions of mesenchymal stem cells in the body?

Mesenchymal stem cells impact beneficial change in the body via their self-renewal, immunomodulatory, anti-inflammatory, signalling, and differentiation capabilities. Mesenchymal stem cells (MSCs) may also self-renew by dividing and maturing into a variety of specialised cell types seen in a particular tissue or organ. Adult stem cells, such as mesenchymal stem cells, pose no ethical issues since they are not derived from embryonic tissue.
