Figure 1. Expression of thrombopoietin (TPO) mRNA in human cerebral hemisphere and cerebellum. There was no correlation between the TPO levels in blood plasma and cerebrospinal fluid (CSF). (A) TPO mRNA expression in human cerebral hemisphere and cerebellum was detected by RT-PCR, n = 3. (B) Scatter plot of TPO levels in blood plasma and CSF, r = –0.09, P = 0.80, n = 10.
