SOX7-enforced expression promotes the expansion of adult blood progenitors and blocks B-cell development.

ABSTRACT: During embryogenesis, the three SOXF transcription factors, SOX7, SOX17 and SOX18, regulate the specification of the cardiovascular system and are also involved in the development of haematopoiesis. The ectopic expression of SOX17 in both embryonic and adult blood cells enhances self-renewal. Likewise, the enforced expression of SOX7 during embryonic development promotes the proliferation of early blood progenitors and blocks lineage commitment. However, whether SOX7 expression can also affect the self-renewal of adult blood progenitors has never been explored. In this study, we demonstrate using an inducible transgenic mouse model that the enforced expression of Sox7 ex vivo in bone marrow/stroma cell co-culture promotes the proliferation of blood progenitors which retain multi-lineage sh
