UPenn Digestive and Liver Center

The mission of the UPenn Digestive and Liver Center is to unite investigators with interests in digestive and liver disease in the exploration of creative experimental approaches, as well as to stimulate others to enter these areas of research. The scientific focus of the Center revolves around host-environmental interactions in digestive and liver disease research from bench to bedside. The Center is divided into three thematic areas: Intestinal Biology, Liver Biology, and the Microbiome. Center resources include five biomedical research cores to support research in both model systems and human subjects, a pilot & feasibility program, and various enrichment activities including a weekly seminar series, liver and intestinal stem cell clubs, and an annual retreat.

Announcements

Message from Our New Center Director, Ken Cadwell!

Dear Colleagues and Friends, 

I am honored to step into the role of Director of the UPenn Digestive and Liver Center and to have the opportunity to serve such an accomplished community. As I begin this new chapter, I first want to express my deep gratitude to Dr. Gary Wu for his exceptional leadership and dedication over the years. Gary’s contributions have been instrumental in shaping the Center’s success, and I am delighted that he has graciously agreed to continue serving as a co-Associate Director alongside Dr. Becky Wells. I am lucky to have their guidance as we build on the strong foundation they have established and navigate the challenges that may arise during this politically volatile period. 

This edition of our quarterly newsletter brings exciting updates, including the announcement of our pilot award winners. The selection process was highly competitive, with a remarkable number of outstanding applications. This is a testament to the innovative research happening across our community. Congratulations to the awardees; your work embodies the excellence we strive to foster. 

You may also notice that we’ve simplified our name to the UPenn Digestive and Liver Center, a change intended to make our identity clearer and easier to remember while staying true to our mission. 

In my new role, I am committed to supporting our excellent core services and promote community building through the many enrichment activities organized by the Center. I look forward to working with all of you to drive our Center’s continued growth and impact. 

Warm regards,  Ken

  • Utilizing single-cell data for per-cell type eQTL mapping in the human pancreas Saturday, October 10, 2026

    CONCLUSIONS/INTERPRETATION: We identified new signals that were previously not found in bulk pancreatic eQTL studies and potential cell type of action for several signals that were identified previously. Although there are limitations to the power, and therefore, discoverability of this study, it provides insights into how individual pancreatic cells differently contribute to metabolic disease.

  • SOX4 Reprograms Adipose Stromal Cells into a Cancer-Associated Fibroblast- like State to Drive Metabolic Disease Saturday, October 10, 2026

    Pathogenic adipose tissue remodeling promotes metabolic disease in obesity, but the mechanisms that establish this unhealthy tissue state remain poorly understood. Here, we show that obesity drives SOX4-dependent reprogramming of mesenchymal stromal cells (MSCs) into cancer-associated fibroblast-like (CAF-like) cells that promote adipose tissue dysfunction. TGFβ signaling is elevated in obesity and activates SOX4 in mouse and human MSCs, inducing their conversion to a CAF-like state. In mice,...

  • Enabling subcellular DESI-MSI for broad adoption: Acquisition, analysis, and application Saturday, October 10, 2026

    Subcellular mass spectrometry imaging (MSI) has required specialized instrumentation and approaches. Additionally, data analysis has required expensive proprietary software, or code-based open-source tools. These barriers render spatial metabolomics less accessible than peer spatial omics techniques (transcriptomics, proteomics). Here we demonstrate subcellular MSI on standard commercial hardware, analyzed using code-free, open-source software. An inexpensive, fully reversible modification of a...
