Sources of adult mesenchymal stem cells and their applicability for musculoskeletal applications.

There is significant potential for the use of adult mesenchymal stem cells in regenerating musckuloskeletal tissues. The sources of these stem cells discussed in this review are bone marrow, blood, adipose tissue, synovium, periosteum & cartilage. Adult mesenchymal stem cells of bone marrow origin are the cells which are heavily investigated in many studies and have been shown capable of producing a variety of connective tissues especially cartilage and bone.

Regulation of differentiation of mesenchymal stem cells into musculoskeletal cells.

Mesenchymal stem cells (MSCs) are multipotent cells that have the capability of differentiating into several different cells such as osteoblasts (bone), chondrocytes (cartilage), adipocytes (fat), myocytes (muscle) and tenocytes (tendon). In this review we highlight the different regulators which determine the lineage a particular MSC will differentiate into. Mesenchymal stem cells are increasingly being used in tissue regeneration and repair.

Advances and developments in the use of human mesenchymal stem cells - a few considerations.

One less visited area in musculoskeletal stem cell research is the effects of donor age on quality of stem cells. The prevalence of degenerative orthopaedic conditions is large, and the older population is likely to receive great benefit from stem cell therapies. There are many known growth factors involved in controlling and influencing stem cell growth which are also related to cell senescence.
