- *30 mice from 3 independent experiments (10 mice in each experimental group) were cervically dislocated on the 15th day after left cardiac ventricle injection of 5 × 104 melanoma cells in 0.1 ml HEPES-buffered DMEM. See "Materials and Methods" section for details.
- †Each bone was scored as either containing a metastatic nodule or being free of microscopic tumor, and the percentage of bones positive for metastases was calculated for the total number of bones sites.
- The number of recorded metastases per bone segment (maximum of 10) was multiplied by the surface percentage occupied by metastases (maximum of 100) and expressed as a relative percentage with respect to a previously defined maximum for each individual bone segment. Data represent average values ± SD (n = 30).
- Paired and multiple bones were considered as single organ sites with the incidence and metastasis development index calculated including both or all the bones within an animal.
