Cell lines	Average time (d)	Bone metastases∆
*: The average time from the left cardiac ventricle injection to the appearance of the bone metastases consumed in each group; **: The number of mice with bone metastases identified by radiological examination and pathological sections/the total number of mice in each experimental group; ∆: There was no statistical difference in the bone metastatic rate among the experimental groups.
