Fig. 4From: Finite mixture clustering of human tissues with different levels of IGF-1 splice variants mRNA transcriptsKernel density estimates of the distribution of IGF-1 Eb splice variant mRNA compositional ratios in a cohort of 20 different human tissues. IGF-1 Eb splice variant mRNA compositional ratio (Ratio 2) is defined in Fig. 2 and in Table 1.
