This study reveals distinct patterns in B cell progenitors in prenatal and adult models, suggesting key signaling differences impacting hematopoietic malignancies.
Key Points
A multiomics atlas covering over 500k cells was created, enabling in-depth analysis of B lymphopoiesis across developmental stages.
Findings show a novel postnatal B cell subset similar to prenatal precursor cells, indicating a unique differentiation pathway.
The study identifies various molecular signatures in prenatal cells, linking them to enhanced proliferation and leukemia characteristics.
The experimental framework to generate B cell precursors from hiPSCs provides a valuable model for studying B cell development.
