Mukherjee's lab, with the help of PureTech Health plc, has been investigating chimeric antigen receptor redirected T cells (CAR-T) therapy in a joint venture called Vor BioPharma since 2016.[44] They have combined CAR-T therapies with genetically modified hematopoietic stem cells to specifically target malignant hematopoietic lineages, while transplanted stem cells replenish the lineage but remain antigenically concealed. This technology has been developed so that, in addition to B cell malignancies, other lineage specific cancers could be targeted.[45] This provides an important new approach to managing acute myeloid leukemia.[46]
