Stem Cell Therapy for Lung Diseases
The capability of stem cells to locally repair damaged tissue offers the possibility for cell-based treatment of most irreversible diseases, including chronic lung diseases. Lung transplantation is considered a viable treatment option for progressive and irreversible lung diseases. Unfortunately, the number of donors is insufficient to meet demand. Transplantation is hindered by a shortage of organ donors and severe surgical, technical and immunological complications, which urge innovative therapeutic approaches.(1)
It is important to note that, on a daily basis, regardless of where we live and our age, the respiratory system is continuously exposed to various irritants such as inhaled toxins, carbon granules, pathogens, and their products. Pulmonary homeostasis (natural self-regulating process by which our organism maintains balance adjusting to external and internal conditions) is maintained by interaction between alveolar epithelial cells and lung-resident immune cells that continually monitor the pulmonary microenvironment, induce tolerance to innocuous inhaled particles, or provide efficient immune reactions against invading microbes.(2)
Why is this relevant?
Respiratory diseases impose a remarkable global healthcare burden. Current data show that 235 million people have asthma, at least 200 million suffer from chronic obstructive pulmonary disease (COPD), 65 million struggle with moderate-to-severe COPD, and more than 50 million people endure occupational lung diseases. Four million people die annually from chronic respiratory disease before reaching mature ages. COPD is the fourth leading cause of death worldwide.(3)
How does stem cell therapy help treat pulmonary and respiratory diseases?
Mesenchymal stem cells (MSCs), which are favored in our personalized protocols for each of our patients in Giostar Mexico, are multipotent adult stem cells, followed with significant interest by the medical and scientific community since their initial discovery.(4) MSCs have potential application in regenerative medicine, in which they are thought to aid in the repair and regeneration of otherwise physiological damage and incurable diseases, including neurological disorders, immunological diseases, articular cartilage damage and the development of irreversible lung fibrosis.(5)
It has been demonstrated that intratracheal administration of MSCs positively regulated airway remodeling, attenuated inflammation and improved function, suggesting their ability to maintain and promote tissue homeostasis in experiments in the course of allergic asthma.(6)
In addition to their regenerative and immunosuppressive effects responsible for the attenuation of Acute Respiratory Distress Syndrome (ARDS), MSCs are also able to promote resolution of ongoing inflammation, which reduces pulmonary edema.
The therapeutic potential of MSCs in the treatment of ARDS has been evaluated in several, already completed, clinical trials.(7) A cited study demonstrated that single intravenous infusion of allogeneic BM-MSCs (1, 5, or 10 million cells/kg of body weight (bw)) was well tolerated in nine patients with moderate to severe ARDS (FDA approved clinical trial: NCT01775774). Side events, clinical instability, or dose-limiting toxicity was not observed in any of the nine patients that received allogeneic BM-MSCs. Results obtained in this study were used as an optimistic starting point for a larger randomized, multicenter, phase 2 clinical trial that was conducted from 2014 to 2018 in the United States (FDA approved clinical trial: NCT02097641).(8)
