He is a former Director of the Hematology and Molecular Diagnostics laboratories and was Director of the URMC Labs until his appointment as Department Chair in 2004. His research established molecular events determining B lymphoid lineage commitment and early differentiation of human B cell progenitors. He has recently focused on the elucidation of the role of common genetic variants in determining outcome of patients following a coronary event.ResearchWe are interested in the molecular events determining B lymphoid lineage commitment and early differentiation of B cell progenitors. Insight into the regulation of B cell development can be applied to studies of childhood lymphoblastic leukemia, a neoplasm derived from an early B lymphoid progenitor which cannot properly commit and/or differentiate into a mature B cell. Signals for human B cell development are incompletely understood, largely due to difficulties in culturing normal human B cell progenitors. Using a bone marrow stromal dependent culture system, we have identified colony forming human lymphoid progenitors in a very early bone marrow population (CD34+/CD19-/IL-7 receptor -) which expresses early myeloid as well as lymphoid markers, and may therefore represent cells engaged in the earliest steps of commitment to two of the major hematopoietic lineages, lymphoid and myeloid. This experimental system can be used to define critical molecular events determining the commitment of early human hematopoietic progenitors to B lymphoid differentiation. The goal of my research is to characterize the signals for lineage commitment and B lineage differentiation of these early human lymphoid progenitors. Efforts focus on analysis of immunoglobulin gene rearrangements of individual progenitors as an indicator of early B lineage commitment using advanced cell sorting and micromanipulation techniques, and transfer of B lineage specific regulatory genes directly into normal human hematopoietic progenitors to assess their contribution to B lineage commitment and development.CredentialsEducation1975MD | Johns Hopkins University School of Medicine (USA)Post-doctoral Training & Residency07/01/1976 - 06/30/1981Fellowship in Pathology at University of Rochester Medical Center07/01/1975 - 06/30/1976Residency in Pediatrics at University of Rochester School of Medicine GMEAwards2000My Fifth Award University of Rochester Medical Center1999My Fourth Award University of Rochester Medical Center1998My Third Award University of Rochester Medical CenterVIEW ALL expand_morePatentsPatent Title: Identifying Risk of a Medical Event Patent #: 8,979,753 Issue Date: Mar 17, 2015 Country: United States Invented By: James P Corsetti, Arthur J Moss, Daniel H Ryan, Charles E SparksPublicationsJournal Articles7/2016Corsetti JP, Salzman P, Ryan D, Moss AJ, Zareba W, Sparks CE.
