Research Summary

The Peng Lab is interested in how fibroblasts integrate extracellular cues to modify the tissue niche, with a particular focus on fibroblasts that support tissue-resident stem cells and immune cells. We utilize complex murine genetic models and human specimen to interrogate how fibroblasts maintain organ homeostasis, initiate disease, and drive tissue aging. Tien is a pulmonologist by training and the lab utilizes the lung as a model organ due to its immense cellular diversity and architectural complexity.
