The grains of salt represent the microvessels in a cross section of tissue.
Aerenchyma formation was analyzed in freehand root cross section of tissue stained with phloroglucinol/HCl and mounted in 50% glycerol.
However, the inverse problem of DOT is ill-posed and highly nonlinear due to the zig-zag propagation of photons that diffuses through the cross section of tissue.
The FFPE blocks were made from thin cross sections of tissues collected for snap-frozen tumor banking and were initially intended for a histological quality check of the banked tissue.
However, as a simple example of such a calculation, we will imagine two-dimensional (2D) cross sections of tissue that have been stained to reveal microvessels as discrete points.
In order to evaluate the expression of SMC markers in the vascular constructs derived from all four cells types, cross sections of tissue-engineered vessels were immunostained with the same markers as 2D cultures presented in Figure 1.
The observation of adipose tissues with OCT can roughly display the honeycomb textures on the vertical cross section of biological tissues [ 18– 218.
Cross section of colon tissues were fixed in 10% formaldehyde solution then embedded into paraffin wax blocks and cut using a microtome.
Given that somatic HD CAG instability occurs in many tissues to varying extents [ 3, 6, 17], we reasoned firstly, that tissue specificity may governed by many factors, and secondly, that studying a large cross-section of tissues with different instabilities would provide the most information concerning the major factors underlying tissue instability patterns.
Using the procedure described above, we have calculated the fractional probabilities for at least one hot spot in the various regions of the breast assuming a Poisson distribution of microvessels in a 2D cross section of breast tissue.
A small cross section of colon tissue from each group was fixed in 10% formaldehyde solution for histopathological screening.
