A chimeric mouse model was created through the injection of bone marrow cells from GFP transgenic C57BL/6 mice into the tail veins of recipient wild-type C57BL/6 mice.
This chimeric mouse model was subjected to pulpectomy and pulp revascularization to study the process in which bone marrow derived cells were involved in revascularization of pulp tissue.
Dynamic fluorescence imaging in vivo and immunofluorescence were used to explore mechanisms of bone marrow derived cells involved in the process of pulp revascularization.
