Stem Cell Therapy Pulmonary Fibrosis


Stem Cell Treatment for Pulmonary Fibrosis and COPD are now available at SIRM

Pulmonary fibrosis is the formation or development of excess fibrous connective tissue (fibrosis) in the lungs. It is also described as "scarring of the lung."

Pulmonary fibrosis is suggested by a history of progressive shortness of breath (dyspnea) with exertion. Sometimes fine inspiratory crackles can be heard at the lung bases on auscultation. A chest x-ray may or may not be abnormal, but high Resolution CT will frequently demonstrate abnormalities.


Symptoms of pulmonary fibrosis are mainly:

  • Shortness of breath, particularly with exertion
  • Chronic dry, hacking coughing
  • Fatigue and weakness
  • Chest discomfort
  • Loss of appetite and rapid weight loss

Stem Cell Therapy Pulmonary Fibrosis and COPD

Possible Causes

Pulmonary fibrosis may be a secondary effect of other diseases. Most of these are classified as interstitial lung diseases. Examples include autoimmune disorders, viral infections or other microscopic injuries to the lung. However, pulmonary fibrosis can also appear without any known cause. In this case, it is termed "idiopathic". Most idiopathic cases are diagnosed as idiopathic pulmonary fibrosis. This is a diagnosis of exclusion of a characteristic set of histologic/pathologic features known as usual interstitial pneumonia (UIP). In either case, there is a growing body of evidence which points to a genetic predisposition in a subset of patients. For example, a mutation in Surfactant protein C (SP-C) has been found to exist in some families with a history of pulmonary fibrosis.

Diseases and conditions that may cause pulmonary fibrosis as a secondary effect include:

  • Inhalation of environmental and occupational pollutants, such as in asbestosis, silicosis and exposure to certain gases. Coal miners, ship workers and sand blasters among others are at higher risk. Hypersensitivity pneumonitis, most often resulting from inhaling dust contaminated with bacterial, fungal, or animal products.
  • Cigarette smoking can increase the risk or make the illness worse.
  • Some typical connective tissue diseases such as rheumatoid arthritis and Scleroderma. Other diseases that involve connective tissue, such as sarcoidosis and Wegener's granulomatosis.
  • Infections
  • Certain medications, e.g. amiodarone, bleomycin, busulfan, methotrexate, and nitrofurantoin
  • Radiation therapy to the chest.

J Huazhong Univ Sci Technolog Med Sci. 2015 Dec;35(6):828-33 Authors: Liu HM, Ma LJ, Wu JZ, Li YG Abstract Bone marrow mesenchymal stem cells (MSCs) transplantation could repair injury tissue, but no study confirms whether MSCs can promote the proliferation of endogenous lung stem cells to repair alveolar epithelial cells of mice with chronic obstructive pulmonary disease (COPD). This study was designed to investigate the effect of MSCs on the proliferation of endogenous lung stem cells in COPD mice to confirm the repair mechanism of MSCs. The mice were divided into control group, COPD group, and COPD+MSCs group. The following indexes were detected: HE staining of lung tissue, the mean linear intercept (MLI) and alveolar destructive index (DI), the total cell number in bronchoalveolar lavage fluid (BALF), pulmonary function, alveolar wall apoptosis index (AI) and proliferation index (PI), the number of CD45(-)/CD31(-)/Sca-1(+) cells by flow cytometry (FCM), and the number of bronchoalveolar stem cells (BASCs) in bronchoalveolar duct junction (BADJ) by immunofluorescence. As compared with control group, the number of inflammatory cells in lung tissue was increased, alveolar septa was destroyed and the emphysema-like changes were seen, and the changes of lung function were in line with COPD in COPD group; AI of alveolar wall was significantly increased and PI significantly decreased in COPD group. There was no significant difference in the number of CD45(-)/CD31(-)/Sca-1(+) cells and BASCs between control group and COPD group. As compared with COPD group, the number of inflammatory cells in BALF was decreased, the number of CD45(-)/CD31(-)/Sca-1(+) cells and BASCs was increased, AI of alveolar wall was decreased and PI was increased, and emphysema-like changes were relieved in COPD+MSCs group. These findings suggested that MSCs transplantation can relieve lung injury by promoting proliferation of endogenous lung stem cells in the cigarette smoke-induced COPD mice.
