Yesterday, October 7, Sir John Gurdon passed away. Dr. Gurdon was awarded the Nobel Prize in Physiology or Medicine in 2012, together with Shinya Yamanaka. Through a series of experiments using Xenopus eggs, Gurdon showed that the nucleus of a mature cell can be reprogrammed to a pluripotent state.

Aberrant intermediate alveolar epithelial cells promote pathogenic activation of lung fibroblasts in preclinical fibrosis models - Nature Communications
The direct contribution of aberrant epithelial cells to lung fibrosis is largely unknown. The authors use murine and human systems to identify how these cells activate fibroblasts, and how reciprocal signals cause them to enter a profibrotic state.
