Investigation of Small Mobile Stem Cells (SMS Cells) in Participants With Chronic Obstructive Pulmonary Disease (COPD).

The suspension of stem cells will be put in a medical nebulizer machine, commonly used to deliver medicines into the lungs through inhalation. This means that the participants will breathe in the mist containing the SMS cells, produced by the nebulizer machine. This is a Phase I First-in-Human study, which indicates that this treatment is being studied for the first time in humans.
