Abstract:
Objective To investigate cell type and size of fetus atrioventricular node. Methods Using the technique of paraffin section, H-E staining, the cellular morphology and size of atrioventricular node in fetus hearts were observed under microscope, and quantitied by HIPAS-1000 computerized image analytical instrument. Results The cell types of atrioventricular node in fetue hearts were composed of light, dark and transitional cells. The morphology of light and dark cells were spindle-shaped or ellipsoid, but a few cells were polygonal. The shape of transitional cells was short column. The nuclei of light cells and transitional cell were larger than that of dark cells.Conclusion Pacemaker cell of atrioventricular node in fetus heart includes light and dark cells which could present different function types of pacemaker cell.
