Research Summary

The Peng Lab is interested in how the mesenchymal compartment integrates extracellular cues to modify the niche, with a focus on the niche supporting resident tissue stem cells. We utilize complex murine genetic models and human specimen to interrogate how mesenchymal compartments 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.
