For morphometric analyses, 2- to 3-μm cross-sections of anterior compartment specimen were deparaffinized and stained with hematoxylin and eosin (H&E) using routine procedures as described previously (8).
Furthermore, we did not find the presence of any ectopic thyroid tissue or thyroid rests in any of the central compartment specimen, although this was believed to be present in up to 20% of cases.
Also, we could not dissect the expression to either the epithelial or the stromal compartment as the specimens obtained were a mixture of these.
The data for relations of IGF-1 expression and age are contradictory, showing either positive [ 26] or negative [ 27] associations probably depending on the sample population and the compartment, where the specimens were collected.
In this work we introduce a segmentation method targeted at membranes, which define the natural limits of compartments within biological specimens.
The mouse mammary gland contains a high percentage of adipocyte as well as the epithelial cells that form cancer, thus, the protein change was normalized by the size of the epithelial cell compartment in the specimen, using cytokeratin, and for protein loading using GAPDH.
Analysis of the lateral compartment in non-OA specimens compared to OA specimens indicated that there was a biochemical difference, with more intracategory variance, in the non-OA specimens.
With regard to subchondral bone thickness, the medial compartment of the OA specimens was significantly thicker than the lateral compartment, and was significantly thicker in OA specimens compared to non-OA specimens.
However, elevated levels of homotrimeric collagen and associated spectral differences were also found in the grossly normal lateral compartment of the OA specimens, indicating that the whole joint is affected.
Since we had previously shown that the various ERβ isoforms formed heterodimers with ERβ1 in cell culture under different conditions of ligand stimulation (Leung et al. 2006), we calculated Spearman correlation analyses to determine the possibility of finding two of the three ERβs in the same cellular compartment in the PCa specimens (Table 2).
