Isseroff Lab - Skin Wound Healing 

Dr. Isseroff’s research interests include keratinocyte differentiation, migration and wound healing, signal transduction, bioengineered tissue replacement, and toxicology of the skin. Current research projects focus on analysis of cell responses to an applied electric field, bioengineered skin replacements, and enhancers of wound healing. She also directs a multi-specialty wound healing clinic within the VA Northern California Health Care System’s Sacramento Medical Center, which houses a clinical research unit actively carrying out both investigator and industry-initiated clinical trials for novel approaches to improve wound healing.
