Pulmonary Fibrosis. A debilitating disease that restricts a person’s lung capacity, controllable with drug therapies, but it’s only “cure” is a double lung transplant. Researchers at TGen have released the results of a study that investigated the disease on a cellular level. Using advanced spatial transcriptomics, they identified hidden disease markers in seemingly healthy lung tissue—offering hope for earlier, more personalized treatments. Targeting these early disruptions could improve lung function and outcomes. With current PF treatments only slowing decline, this discovery, published in Nature Genetics, marks a step toward preventing irreversible damage. In this episode of TGen Talks, Nicholas Banovich, Ph.D., discusses the Nature Genetics finding and the new spatial map of gene expression in lung cells. Instead of blending tissue together and analyzing it, scientists can now examine individual cells and pinpoint where molecular changes happen. We’ll break down what this means, how it’s done, and why it could change the way we study lung disease.
