Mechanical stimulation is an essential factor affecting the metabolism of bone cells and their precursors. We hypothesized that vibration loading would stimulate differentiation of human adipose stem cells (hASCs) towards bone-forming cells and simultaneously inhibit differentiation towards fat tissue. We developed a vibration-loading device that produces(More)
Human adipose stem cells (hASCs) have been recently used to treat bone defects in clinical practice. Yet there is a need for more optimal scaffolds and cost-effective approaches to induce osteogenic differentiation of hASCs. Therefore, we compared the efficiency of bone morphogenetic proteins (BMP-2 and BMP-7), vascular endothelial growth factor (VEGF), and(More)
OBJECTIVE To evaluate the basic structures and processes of asthma care 6 years after the launch of the Finnish Asthma Programme. The evaluation will serve as the baseline for the implementation of the evidence-based guidelines for asthma published in 2000. DESIGN A descriptive type-2 evaluation (managerial monitoring of a policy implementation), based on(More)
