Abstract
Mesenchymal stem cells (MSCs) are a populace of non-hematopoietic multipotent stromal cells, which have the ability to differentiate into tissue derived from a single germ layer. MSCs have been isolated from various sites, including adipose tissue, skeletal muscle, synovium, spleen, thymus, lung and amniotic fluid, but are most often isolated from bone marrow. MSCs have several valuable functions that make them a promising therapeutic option in the field of regenerative medicine, including the secretion of anti-inflammatory cytokines and growth factors, the migration of cells to the site of injury when administered and the ability to ‘rescue’ cells through the transfer of functional mitochondria. They also offer the possibility of autologous cell transplantation, circumventing immune rejection. These properties, among others, make MSCs a promising potential therapeutic agent in the treatment of chronic lung diseases with high rates of morbidity and mortality, such as idiopathic pulmonary fibrosis (IPF), COPD and obstructive bronchiolitis (OB). Numerous animal models have shown the protective and reparative effects of MSCs in models of experimental lung injury. There are currently several clinical trials underway to evaluate the safety and efficacy of MSCs in the treatment of IPF, COPD and OB. While early results are encouraging, a considerable amount of research must be done concerning the safety MSCs, as well as their optimal dosage, time and route of administration. In addition, much is still unknown about the pathogenesis of these chronic lung diseases, as well as the mechanisms MSCs utilize to assist in their repair.

Abstract
Chronic Obstructive Pulmonary Disease (COPD) can be briefly described as air flow limitation and chronic dyspnea associated to an inflammatory response of the respiratory tract to noxious particles and gases. Its main feature is the obstruction of airflow and consequent chronic dyspnea. Despite recent advances, and the development of new therapeutic, medical and clinical approaches, a curative therapy is yet to be achieved. Therapies involving the use of tissue-specific or donor derived cells present a promising alternative in the treatment of degenerative diseases and injuries. Recent studies demonstrate that mesenchymal stem cells have the capacity to modulate immune responses in acute lung injury andpulmonary fibrosis in animal models, as well as in human patients. Due to these aspects, different groups raised the possibility that the stem cellsfrom different sources, such as those found in bone marrow or adipose tissue, could act preventing the emphysematous lesion progression. In this paper, it is proposed a review of the current state of the art and future perspectives on the use of cell therapy in obstructive lung diseases.

Abstract
According to significant improvements in the tissue engineering field over the past several years, lung tissue cells have recently attracted more attention due to the high prevalence and diversity in related diseases. However, selection of an appropriate cell type, screening of suitable conditions for growth and proliferation, as well as subsequent implantation into the body to repair and regenerate damaged tissues are considered as important issues in this context. It should also be noted that most studies have been described in animal models, but not in humans. Because of the high regenerative capacity, predominant immunomodulatory feature, and inhibition of T-lymphocyte proliferation, mesenchymal stem cells (MSCs) may play an important role in the reconstruction of damaged tissues including bronchioles in pulmonary diseases. Interestingly, clinical trial studies demonstrated that MSCs have the significant potential to treat a wide variety of diseases including acute myocardial infarction (AMI), liver cirrhosis, crohn’s disease, and graft-versus-host disease (GVHD).
