In-vitro cell quantification method based on depth dependent analysis of brain tissue microscopic images

摘要

In this study we developed a new automatic quantification method to count the number of targeted fluorescently labeled molecules of in-vitro rat brain tissue images. NG2+ glial cells were monitored in order to detect their proliferation to their same kind of cells or to another astrocyte cells using different fluorescently labeled molecules. The method is based on morphological segmentation followed by depth-dependent detection operation applied to a stack of confocal microscopic images. The number of local maxima peak points was used to count the number of the labeled cells. The method shows good promise for the computer-aided assessment in neurological studies for accurate automatic counting systems.
