International experts from multiple disciplines gathered at Homerton College in Cambridge, UK from September 12-14, 2018 to consider recent advances and emerging opportunities in the clonal tracking of hematopoiesis in one of a series of StemCellMathLab workshops. The group included 35 participants with experience in the fields of theoretical and experimental aspects of clonal tracking, and ranged from doctoral students to senior professors. Data from a variety of model systems and from clinical gene therapy trials were discussed, along with strategies for data analysis and sharing and challenges arising due to underlying assumptions in data interpretation and communication. Recognizing the power of this technology underpinned a group consensus of a need for improved mechanisms for sharing data and analytical protocols to maintain reproducibility and rigor in its application to complex tissues.
