Cindy M. Martin, MD
Assistant Professor of Medicine
Director, Lillehei Heart Institute Stem Cell Flow Facility
Co-Director, Adult Congenital and Cardiovascular Genetics Clinic
Born in Ashland, Louisiana, Dr. Cindy Martin graduated from Louisiana Tech University with a Bachelor of Arts Degree in Chemistry. She received her M.D. from Louisiana State University School of Medicine. Dr. Martin then received her Internal Medicine Residency Training at UT Southwestern Medical Center in Dallas, Texas. Following her residency training, she pursued a formal three-year postdoctoral fellowship in molecular cardiology in Dr. Daniel J. Garry’s laboratory. After completing additional fellowships in general cardiology and advanced heart failure and transplantation at UT Southwestern Medical Center, Dr. Martin joined the faculty of the University of Minnesota Cardiovascular Division. Her practice primarily focuses on patients with advanced heart failure however Dr. Martin is also interested in adult patients with congenital or inherited cardiovascular disease. Since joining the faculty of the University of Minnesota Cardiovascular Division, Dr. Martin in conjunction with pediatric cardiologists Dr. Jamie Lohr and Dr. Lee Pyles has established the Adult Congenital and Cardiovascular Genetics clinic here at the University of Minnesota. The clinic is designed to meet the growing needs of late teen and adult patients with congenital heart disease and genetic or acquired conditions which may affect the heart including Marfan Syndrome, Muscular Dystrophy and cardiomyopathies. Dr. Martin hopes that the clinic will be able to provide a smooth transition for patients in their late teens from a pediatric cardiologist into lifelong cardiology care. The clinic will also provide opportunities for patients to participate in clinical research projects aimed at improving the health and quality of life of patients with congenital heart disease, as well as understanding the genetic causes and risk factors associated with these conditions.

Dr. Martin’s basic science research interests focus on stem cell biology, early cardiac progenitors including SP (side population) cells, their role in cardiovascular development and regeneration. Her lab focuses on a persistent stem cell, the SP cell, population within the adult heart. She has defined a molecular marker for this unique cell population, Abcg2 (an ATP-binding cassette half-transporter). She has demonstrated that the Abcg2 expresing cardiac SP cell population can proliferate, differentiate and is capable of participating in myocardial regeneration. She has also shown that Hif-2α is a direct upstream regulator of the Abcg2 gene which functions as a cytoprotective factor for the cardiac SP cell population. As a significant percentage of her clinical time is now spent caring for adults with congenital heart disease who have developed heart failure she continues to focus on the transcriptional regulation of cardiac progenitor cell populations including defining the transcriptional regulation of the Nkx2-5 expressing cells. Dr. Martin has idenitified several downstream target genes of Nkx2-5 including Cripto (Tdgf1) which is the focus of her current studies. She has confirmed that Cripto is an authentic direct downstream target of Nkx2-5 using multiple molecular biological techniques and is exploring the role of Nkx2-5 and Cripto in the left-right patterning during early cardiac development.
