Chronic obstructive pulmonary disease affects more than 65 million people worldwide. Lung transplantation is the only definitive treatment. However, donor availability is limited in meeting the demand. ⋯ The lung's ability to regenerate extensively after injury suggests that this capability could be promoted in diseases in which loss of lung tissue occurs. Lung bioengineering offers the potential to drastically extend life expectancy in patients with end-stage lung disease. If lung reengineering were successful, it would revolutionize the world of transplantation.

Biomarkers are becoming crucial in ever more medical tasks and are proposed to change medicine in profound ways. By biomarking ever more attributes of human life, they tend to blur the distinction between health and disease and come to characterize life as such. Not only do biomarkers strongly influence the professional conception of disease by pervading ever more diagnoses, but they also impact patients' experience of illness. To manage how biomarkers influence patients, professionals, and societies, we urgently need to move from identifying potentially relevant biomarkers to determine their meaning and value to individuals, professionals, and public health.
