CHaoqun’s paper in collaboration with the molofsky lab highlights the role of fibroblasts in modifying resident lymphocytes in the lung, which can in turn suppress alveolar stem cells and induce a copd phenotype.

Soledad’s paper identified fibroblasts with senescent characteristics that serve as tissue sentinels, capable of responding to inflammation to augment stem cell repair at the barrier.

Human alveolar type 2 epithelium transdifferentiates into metaplastic KRT5+ basal cells

Kathiriya JJ, Wang C, Zhou M, Brumwell A, Cassandras M, Le Saux CJ, Cohen M, Alysandratos KD, Wang B, Wolters P, Matthay M, Kotton DN, Chapman HA, Peng T. Nature Cell Biology 2022. PMID: 34969962.

chaoqun and jaymin’s paper in collaboration with the chapman lab demonstrated that pathologic fibroblasts in fibrosis can drive metaplastic differentiation of human alveolar stem cells into basal cells.





Gli1+ mesenchymal stromal cells form a pathological niche to promote airway progenitor metaplasia in the fibrotic lung

Monica Cassandras, Chaoqun Wang, Jaymin Kathiriya , Tatsuya Tsukui, Peri Matatia, Michael Matthay, Paul Wolters, Ari Molofsky, Dean Sheppard, Hal Chapman and Tien Peng. Nature Cell Biology. 2020 Oct 12. PMID: 33046884.

Monica’s paper demonstrated that fibroblasts can modify the metaplastic fate of airway progenitors through hedgehog-BMP antagonism that determines the regenerative outcome.

Expansion of hedgehog disrupts mesenchymal identity and induces emphysema phenotype

Wang C, de Mochel NSR, Christenson SA, Cassandras M, Moon R, Brumwell AN, Byrnes LE, Li A, Yokosaki Y, Shan P, Sneddon JB, Jablons D, Lee PJ, Matthay MA, Chapman HA, Peng T. J Clin Invest 2018. PMID: 29999500.

Chaoqun’s paper demonstrated that differential hedgehog activation in fibroblasts determined segmental fibroblast identities, the disruption of which leads to disease phenotype.
