This plot reveals that MYH7 is expressed in planarian cells. Specifically the upper left section of the plot demonstrates high expression of the gene
Areas labeled 13, 14, and 16 on this plot correspond to the area of high MYH7 expression in the previous plot. These three numbers represent planarian muscle cells.
This plot which only contains planarian muscle cells further supports the hypothesis that there is an MYH7 ortholog expressed in planarian muscle cells!
