Cooperation between both Wnt/β-catenin and PTEN/PI3K/Akt signaling promotes primitive hematopoietic stem cell self-renewal and expansion

Abstract

Li and colleagues investigated the mechanism of stem cell self-renewal using compound mutant mice. The mutation in hematopoietic stem cells combines a Pten deletion and activated β-catenin and demonstrates that activation of either Wnt/β-catenin or PI3K/Akt signaling is not sufficient to expand primitive HSCs, but in combination, both pathways drive self-renewal and expansion of HSCs with long-term functional capacity
