Infiltrating neutrophils induce allospecific CTL in response to immunization with apoptotic cells via MCP-1 production.

abstract：:The switch from fetal to adult hematopoietic stem/progenitor cells (HSPCs) is associated with profound changes in several genetic programs. Although HSPC ageing corresponds to alterations in Wnt signaling, relatively little is known about the relative roles of different Wnt signaling pathways in HSPC ontogeny. We hypo...
