The Nuts and Bolts of Lineage Chimerism Testing
Chimerism analysis is used to monitor the outcome of allogeneic hematopoietic stem cell transplantation. By
looking at the presence of donor leukocytes within specific cell subsets of the host’s peripheral blood, one can assess the
success of donor cell engraftment or detect early graft failure, rejection, or relapse. Prior to performing chimerism analysis, different cell subsets must be isolated from the same sample to perform lineage-specific analysis. In this webinar, Dr.
Cathi Murphey (Immunogenetics Lab Director; Southwest Immunodiagnostics, Texas) will discuss available technologies for isolating different cell subsets from the same sample and improving cell purity prior to chimerism analysis.
Predictive In Vitro Models for Toxicity Testing and Liver Research
Having validated tools to perform predictive assays in a biologically-relevant system is key to success in drug discovery research. In this webinar, Dr. Terry Riss (Promega Corp) and Jennifer Christie (STEMCELL Technologies) discuss products and protocols that enable the incorporation of validated in vitro alternatives to animal models for toxicology studies. First, Dr. Riss presents in vitro assays for 3D cultures that monitor drug-induced cytotoxicity and explains how different assays can be multiplexed to measure multiple cell health parameters. Following this, Ms. Christie describes how to generate mature and functional hepatic organoids using HepatiCult™ and demonstrates their applications in liver research and hepatotoxicity assessment.
