Figure 1From: In vitroeffects of fetal rat cerebrospinal fluid on viability and neuronal differentiation of PC12 cellsTotal protein content of fetal rat CSF. Histogram of total protein concentration in pooled samples of cerebrospinal fluid (CSF) from rat fetuses at days E17 to E20. The data shown are mean ± SEM, n = 5 at each age. There was a significant difference between E17 and E20 ECSF protein content p <0.05).Back to article page
