| Abstract: | Objective To study the growth condition and ultrastructure features of the cultured dental pulp cells.Methods 7-day-old rats were used to get the incisors pulp,0.25% collagenase was used to disperse the dental pulp cells in DMEM.Scanning electron microscope(SEM) and transmission electron icroscope(TEM) were used for the observation.Results The cultured dental pulp cells were fusiform in shape with good growth and cell organelles development and normal cell proliferation and differentiation abilities.Conclusion The collagenase digesting and isolating method for dental pulp cells culture can keep them in good living state and the ability of proliferation and differentiation. |
