Organ transplantation is a modern marvel, with more than 157,000 solid organ, and more than 9,000 marrow and blood transplants occurring worldwide in 2022. Organ donor and recipient matching and compatibility screening has progressed significantly in recent decades as molecular methods have progressed rapidly to support this and other fields. Specifically, typing of human leukocyte antigens (HLAs) has expanded to consider ethnic population variation and cell free DNA (cfDNA) monitoring is now being used to monitor recipients for biomarkers that indicate organ rejection.  

Our guest for this episode, Dr. Lee Ann Baxter-Lowe, Director of the HLA Laboratory at Children's Hospital Los Angeles has been working in the field of transplantation science for virtually her entire career. Join us for a great explanation of the science and a first-hand recounting of developing the assays, from decades ago, before thermal cyclers existed, to her cutting-edge work using digital PCR to progress the field even further. 

Lee Ann also shares very personal aspects of her career journey in her conversation with Cassie. This includes her describing the scientific “studies” of her and her cousin as children, her venturing into the world of HLA typing when it was emerging, and the role her family has played in her career, which gets personal quickly when she shares that her husband is currently dealing with a blood malignancy.
