Abstract Recently many studies have suggested a potential role for early hematopoietic progenitor cell and hematopoietic stem cell HSC recruitment and differentiation in the development of allergy and inflammation. This is based largely on evidence that stem cells or CD34 progenitor cells are recruited to the site of inflammation in allergic diseases likely through many of the same adhesion and chemokine receptors used for stem cell homing to the bone marrow PSGL-l CXCLl2 alpha4-betal integrin CD44 etc . Once at the site of inflammation it has been suggested that stem cells could participate in the perpetuation of inflammation by maturing locally into inflammatory cells in response to the growth factors released in situ. Here we provide a brief review of the evidence to suggest that hematopoietic stem and progenitor cells versus mature hematopoietic lineages are indeed recruited to the site of allergic inflammation. We also discuss the molecules that likely play a role in this process and highlight a number of our novel observations on a specific role
