As shown in Figure 6b, TGF- β1 was localized in the cytoplasm and nucleus in RMS tissues, with some diffuse and local staining.
Future studies should test for local staining of these markers to better evaluate regional remodeling of neuronal subpopulations.
In the present study, the microfilariae with a new histochemical staining pattern (local staining at the anal pore and diffuse staining at the central body) were more common.
The acid phosphatase staining pattern, with local staining at the anal pore and diffuse staining in the central body, was observed in 58 cases (35.4 per cent).
Local staining up to 5% of the tumour area was defined as +, and staining over 5% of the area was defined as ++, respectively.
Healthy tissue analysis showed intensive staining on the baso-lateral surface of epithelial cells of ducts and acini in duct-lobular units, with local staining in myoepithelial cells.
Based on molecular techniques, microfilariae with histochemical staining pattern of "local staining at anal pore and diffuse staining at central body" was identified as D. repens in addition to those showing acid phosphatase activity only at the anal pore.
Sequence analysis of 5.8S-ITS2-28S frDNAent of rDNA gene of microfilariae with the acid phosphatase staining pattern of local staining at the anal pore and diffuse staining in the central body revealed 97percentnt homology with D. repens.
For confirmation of the species of microfilariae with the acid phosphatase staining reaction pattern "local staining at the anal pore and diffuse staining in the central body," sequence analysis of PCR product of 5.8S-ITS2-28S frDNAent of rDNA gene was resorted to.
Interestingly, the staining with S100B antibodies did not overlap with the S100A9 and Aβ patterns: S100B was not detected in plaques and blood vessels, but local staining was observed in tissues surrounding the plaques (Fig. 1c), limited staining was detected around the blood vessel walls and in the white matter of the alveus of hippocampus (supplemental file 1c, low right corner).
