| 方法 | Human mammary epithelial cells are maintained in Mammary Epithelial Basal Medium (MEBM) supplemented with the Mammary Epithelial Growth Media (MEGM) bullet kit. 184 and 184B5 cells are maintained in MEBM sodium-bicarbonate free (MEBM-SBF) supplemented with the MEGM bullet kit, isoproterenol (10 μM), and transferrin (5 μg/ml). MCF10A cell lines are maintained in DME/F12 containing 5% heat inactivated horse serum, penicillin/streptomycin (100 μg/ml and 100 μg/ml), hydrocortisone (1.4μM), insulin (10 μg/ml), choleratoxin (100 ng/ml), and EGF (20 ng/ml). Breast cancer cell lines are maintained in Improved MEM Zinc Option containing 10% fetal bovine serum, 1% glutamine, and 1% penicillin/streptomycin. For growth assays, cells are treated with the different retinoids for the specified number of days with media and treatment changes every other day in T47D cells and every 2 days in 184 cells. Cell proliferation is measured according to the protocol for the CellTiter 96 Aqueous Non-Radioactive Cell Proliferation Assay. This colorimetric assay determines the number of viable cells in a sample. Each point represents samples done in quadruplicate |

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
