We were excited to see our team’s research featured on the front cover of JCI Insight last month!

The article, “Hair follicle epithelial stem cells contribute to interfollicular epidermis during homeostasis,” shows how KROX20-lineage stem cells in hair follicles migrate into the interfollicular epidermis to support skin renewal and barrier function. Through lineage tracing and spatial transcriptomics, the study demonstrates that these cells contribute to both basal and suprabasal layers, and that their depletion disrupts epidermal stratification and homeostasis.

This work underscores the hair follicle as a critical reservoir for maintaining skin health, with implications for future strategies in repair and regeneration.

👏 Congratulations to the UTSW author team — Elnaz Ghotbi, Edem Tchegnon, Ze Yu, Tracey Shipman, Zhiguo Chen, Yumeng Zhang, Renee M. McKay, Chao Xing, Chung-Ping Liao, and Lu Q. Le — on this important contribution.

This , say hello to Benjamin Nanes, M.D., Ph.D., Assistant Professor in the Department of Dermatology at UT Southwestern Medical Center.

Check out our min interview about his work in skin biology and clinical dermatology below 👇

Your lab studies skin architecture and wound healing. What’s one insight from your research that surprised you? And what might be some of the broader implications of understanding how skin remodels after injury?

BN: In order to heal a wound, skin cells have to do two things which are somewhat contradictory: move into the wound to seal the gap while at the same time staying attached to their neighbors to keep the surrounding skin barrier stable. We were surprised to find that the same structures, called keratin filaments, which allow skin cells to form a stable barrier, also control how skin cells move into a wound. We think this connection can help us understand how skin cells decide whether or not to move in to heal an injury and might even help us develop treatments for wounds which do not heal on their own. More broadly, understanding how skin remodels after injury could also help us treat diseases like skin cancer, where the skin keeps remodeling even when there isn’t a wound.

Have any recent advances in imaging, molecular biology, or clinical tools helped accelerate your research?

BN: We work closely with other scientists at UT Southwestern who develop specialized microscopes and other tools that let us look inside skin cells as they move to heal wounds. This has given us an unprecedented level of detail and allowed us to understand how the intricate organization within individual skin cells influences their behavior. Much of what we are able to do now in the lab would not have been possible even a few years ago.

Meet Dr. Rajiv Nijhawan, Associate Professor of Dermatology at UTSW, Director of the Parkland Skin Tumor Clinic, and Assistant Fellowship Director of the Micrographic Surgery and Dermatologic Oncology fellowship program.

Dr. Nijhawan is a fellowship-trained Mohs micrographic surgeon, combining precision cancer removal with advanced reconstructive surgery to deliver both the highest cure rates and the best cosmetic outcomes for his patients.

He has also built a dedicated High-Risk Skin Cancer Transplant Clinic, providing specialized care for immunosuppressed patients who face unique challenges in skin cancer management.

Check out our mini interview with Dr. Nijhawan below ⬇️

Why did you decide to start the High-Risk Skin Cancer Transplant Clinic, and what impact has it had?

RN: Caring for transplant patients holds personal significance for me, as my father underwent a heart transplant while I was in medical school. This clinic addresses a critical need by providing early detection and timely access to care, as transplant patients face a significantly higher risk of developing skin cancers that often progress more rapidly and aggressively. Through a multidisciplinary and comprehensive approach, we strive to ensure these patients receive the highest level of care. I am proud of the clinic’s meaningful impact in optimizing treatment and outcomes, and it has been deeply rewarding for me to contribute to it as both a clinician and Mohs surgeon.

Where do you see the biggest opportunities for innovation in cutaneous oncology?

RN: There is still much to learn about how and why certain skin cancers develop, and ongoing advances are bringing new possibilities for care. Non-invasive testing may help identify more aggressive cancers earlier, allowing for treatment plans that are personalized to each patient’s unique tumor. In addition, there is great opportunity for research in intralesional and other therapies to potentially shrink cancers, reduce the need for extensive surgery, and in some cases even achieve a complete cure. These innovations would be an important step forward in providing safer, more effective, and more individualized care for our patients.
