RIKEN Center for Integrative Medical Sciences Laboratory for Human Disease Models
Team Leader: Fumihiko Ishikawa (M.D., Ph.D)
Research Summary
The biggest goal of The Ishikawa lab is to develop curative treatments for leukemia. The laboratory pioneered xenograft models for normal human hematopoiesis and patient-derived xenograft (PDX) model for hematologic malignancies using NOD/SCID/IL2rgKO (NSG) mice, in collaboration with Dr. Leonard Shultz at The Jackson Laboratory . Through multi-faceted approach to human leukemia integrating evaluation using PDX models, computational chemistry, structural biology and single cell genomics, Dr. Ishikawa and the team members endeavor to understand the biology of difficult-to-treat hematologic malignancies and find new therapeutic options that tailor to individual patients with highly heterogeneous pathophysiology.
