Isotopic composition is known to vary significantly between different tissue types, which in turn vary in composition over different temporal scales [19], [31], [32].
However, in biomedical media, changes in the refractive index can occur between different tissue types.
Such a visual analysis is quite useful when comparing domain expression patterns between different tissues or cells since protein isoforms with varying domain composition due to alternative splicing can easily be identified (see online tutorial).
Given that the composition of the clock machinery varies between different tissues [3] and that SHARP-1 and -2 interact with the circadian transcriptional oscillator via E-box regulation [12], [15], [26], [27], we asked whether SHARP action might depend on the composition of the E-box activator complex.
The structure and composition of these polymers vary during development not only between different tissues of the same plant, but also from one plant to another [ 5, 6].
Glucosinolate contents and profiles vary between different tissues [36], [37].
Endothelial cell heterogeneity has been described at the level of cell morphology, function, gene expression and antigen composition., Endothelial cell phenotypes vary between different organs, as well as between different tissues of the same organ.
However, there are discrepancies in the literature regarding the ideal physicochemical properties of BCP and the ideal balance between different phase compositions for enhanced bone tissue engineering (M. Ebrahimi, M.G. Botelho, S.V. Dorozhkin, 2016; M. Ebrahimi, P. Pripatnanont, S. Suttapreyasri, N. Monmaturapoj, 2014) [1,2].
The variability in growth rates may be due to different cellular composition in different tissue fragments, or stochastic differences between cells plated in different parental wells.
