  1. 1. CD47–SIRPα : an interaction of importance for bone cell differentiation

    Author : Cecilia Koskinen; Pernilla Lundberg; Per-Arne Oldenborg; Riku Kiviranta; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; CD47; SIRPalpha; osteoblast; osteoclast; SHP-2; Akt2; cell research; cellforskning;

    Abstract : Bone tissue is continuously remodeled by bone-forming osteoblasts and bone-resorbing osteoclasts, in processes tightly regulated by hormones, cytokines and growth factors. CD47, a ubiquitously expressed protein, and one of its ligands, signal-regulatory protein alpha (SIRPα), are two cell-surface proteins belonging to the immunoglobulin (Ig)-superfamily. READ MORE
