Mesenchymal stem cells possess many properties that are ideal for the treatment of inflammatory and degenerative diseases. [6] [7] They can differentiate into many cell types including bone, fat, and muscle which allow them to treat a large range of disorders.
Lung transplantation is the therapeutic measure of last resort for patients with end-stage lung disease who have exhausted all other available treatments without improvement. A variety of conditions may make such surgery necessary. As of 2005, the most common reasons for lung transplantation in the United States were: [2]
Adipose-derived mesenchymal cells are currently the most often used for stem cell treatment of osteoarthritis because of the non-invasive harvesting. This is a recently developed, non-invasive technique developed for easier clinical use. Dogs receiving this treatment showed greater flexibility in their joints and less pain. [94]
Whether the benefits of treatment outweigh the risks for asymptomatic LAM patients with normal lung function is not clear, but some physicians consider treatment for declining patients who are approaching the abnormal range for FEV1. Sirolimus also appears to be effective for the treatment chylous effusions and lymphangioleiomyomatosis.
Lung transplantation is an intricate treatment that can provide efficient results, however, there are risks that come with this procedure which include: bleeding, infection, blockage of the blood vessels to the new lungs, blockage of the airways, severe pulmonary oedema as well as potential blood clot formation.
Lung transplantation is an option if the ILD progresses despite therapy in appropriately selected patients with no other contraindications. [23] [24] Life expectancy after lung transplant is 5.2 years in those with idiopathic interstitial pneumonias (including idiopathic pulmonary fibrosis) and 6.7 years in those with other types of ILD. [8]
Mesenchymal stem cells (MSCs), also known as mesenchymal stromal cells or medicinal signaling cells, are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue).
Lung transplantation is the only therapeutic option available in severe cases. A lung transplant can improve the patient's quality of life. [30] Immunosuppressive drugs can also be considered. These are sometimes prescribed to slow the processes that lead to fibrosis. Some types of lung fibrosis respond to corticosteroids, such as prednisone. [29]
