The primary sporogenous cells divided into the second sporogenous cells which would turn into microspore mother cells in a microsporangium. The cytokinesis in meiosis of the microspore mother cells was of modified simultaneous type, forming the decussate, isobilateral or T-shaped tetrads.

The cell cycle and apoptosis and the expression of P-pg, bcl-2, P53 in the MG63 and MG63/R cell lines were analyzed by flow cytometry. Results The resistance index of the MG63/R cells to cisplatin was 83.557±4.841. The cells also had resistance to doxorubicin, vincristin, methotrexate and cyclophosphamide. Disordered structure of the MG63/R cells was observed through microscopy. The cells appeared in triangle, polygon and polynucleation. The increase of granular endoplasmic reticulums and apophyses was observed through transmission electron microscopy. The proliferation ability of MG63/R increased significantly, with a low apoptosis index.
