Fig. 1From: Computational analysis of mRNA expression profiling in the inner ear reveals candidate transcription factors associated with proliferation, differentiation, and deafnessPCA plot comparing samples in the different ages and tissues according to their mRNA expression. The x- and y-axes are the first and second coordinates, respectively. The samples are colored according to their originating tissue, while the marker shape relates to age. A normal contour line is drawn at 68% probability for each groupBack to article page
