求翻译：三组乳腺癌自发转移模型均在第2天可以检测到4T1-luc2细胞的荧光信号，荧光信号增强与接种细胞的浓度和接种时间成正相关，即细胞浓度越高，时间越长，荧光信号强度数值越高。是什么意思？

Three groups of breast cancer spontaneous metastasis model can be detected in the first two days 4t1-luc2 the fluorescence signal and fluorescence signal is enhanced with the concentration of cells inoculated and inoculated with time into a positive correlation, that is, the higher the cell concentr

Group 3 breast cancer spontaneous transfer model is in the first 2 days that can be detected 4 T 1-luc2 cells of the fluorescent signal, fluorescent signal enhancement and vaccinations and vaccination cell concentrations are related to time, stem cells, the higher the concentration, the longer the t

Three group of breast cancer spontaneous shift model may examine the 4T1-luc2 cell in 2nd days the fluorescence signal, the fluorescence signal enhancement and the vaccination cell density and the vaccination time becomes is being connected, namely the cell density is higher, the time is longer, the

Three spontaneous metastasis in breast cancer models on the 2nd day of 4T1-luc2 cells can be detected fluorescence signal, vaccination and inoculation of cell concentration and enhanced fluorescence signal is positively related, the cell concentration, the higher, longer, fluorescent signal strength
