Summary: Periosteum, a highly vascular and multipotential stromal cell- (MSC-) rich tissue, is vital for fracture healing. In this study, H. E. Owston et al aimed to compare human periosteum and donor-matched iliac crest BM MSC content. They also characterized MSCs in terms of colony formation, growth kinetics, phenotype, cell migration patterns, and trilineage differentiation capacity. Authors have used HoloMonitor M4 to show that in early culture, periosteum cells were less migratory at slower speeds than BM cells. Live cell tracking allowed to determine unique morphological and migration characteristics of periosteal MSCs that can be used to develop novel bone graft substitutes.
