Generation, expansion, and drug treatment of hematopoietic progenitor cells derived from human iPSCs.

Severe congenital neutropenia (CN) is a pre-leukemic bone marrow failure syndrome that can progress to acute myeloid leukemia (CN/AML). Patient material to study leukemogenesis, especially hematopoietic progenitor cells (HPCs) is limited and hard to access. We have established a protocol for generation of HPCs from iPSCs followed by HPC expansion on Sl/Sl feeder cells expressing FLT3L. We performed drug treatment of iPSC-derived HPCs on feeder cells or under feeder-free conditions. Our protocol is also suitable for primary leukemia blasts. For complete details on the use and execution of this protocol, please refer to Dannenmann et al. (2021), (2020), and (2019).
