- Due to the small sample size, further research must be done to collect significant statistical data regarding the amount of MDSCs in bone marrow.
- Two of the three exercised non-tumor bearing rats had to leave the study. In the future, more trials must be run with non-tumor bearing rats in order to collect significant data regarding the effects of exercise on non-cancerous MDSC levels.
- The average spleen weight in sedentary tumor-bearing rats is significantly larger than that of exercised tumor-bearing rats. Further research must be done to determine the cause of this higher blood cell production in sedentary rats.
