To be or notch to be

Constitutive activation of Notch signaling in hematopoietic cells establishes an immortalized hematopoietic stem cell population capable of developing into both myeloid and lymphoid lineages. This system will be useful in determining Notch-mediated mechanisms of hematopoietic differentiation (pages 1278–1281).
