Longitudinal localization of leukaemic stem cells between the metaphysis and central marrow governs their behaviour
Blocking a protein that shelters leukemia stem cells makes them vulnerable to chemotherapy, leveraging an existing drug class.
This Nature Cell Biology study maps AML leukemic stem cell (LSC) niches at three spatial scales in bone marrow, revealing a DPP4-CXCL12-GPC3 axis that controls LSC protection and quiescence in the metaphysis. Targeting DPP4 in AML cells disrupts niche-protective gradients and sensitizes LSCs to chemotherapy, with potential translational relevance given existing clinical DPP4 inhibitors.
What the study was
- Study design
- Preclinical mechanistic study (in vivo mouse AML model with spatial/cellular resolution)
- Population
- Murine AML LSC niche models
- Category
- Drug Development
- Maturity
- Exploratory
- Journal
- Nature Cell Biology
Why it surfaced
High mechanistic novelty (spatial LSC niche mapping at three scales) in top journal; non-human cap applies (score capped at 5). DPP4 inhibitors already in clinical use, giving near-term translational angle.
