Femto-second laser point targeting to induce osteablast contraction. Point targeting using a Spectra-Physics Mai Tai femto-second pulsed laser (800nm) induces a calcium response followed by a cell contraction in an osteoblast cell line. Fluorescence over transmission images captured with an Olympus FV 300 confocal microscope. Cranfield C., Bomzon Z., Day D., Gu M., and Cartmell S. (2006).
