RATIONALE Semaphorin 3A (Sema3A) is a neural guidance cue that also mediates cell migration, proliferation and apoptosis, and inhibits branching morphogenesis. Because we have shown that genetic deletion of neuropilin-1, which encodes an obligatory Sema3A co-receptor, influences airspace remodeling in the smoke-exposed adult lung, we sought to determine(More)
In vitro production of erythrocytes in physiologic numbers from human induced pluripotent stem cells (hiPSCs) holds great promise for improved transfusion medicine and novel cell therapies. We report here, for the first time, a strategy for scalable and xeno-free differentiation of hematopoietic stem/progenitor cells from hiPSCs and subsequent erythrocytes(More)
