Heterogeneous staining and slight background staining was noted in most of the TMA core samples studied.
Slight CD34 staining was noted on small-caliber blood vessels within the stroma.
In the esophageal epithelium of wild-type mice slight background staining was observed.
A slight membrane staining was also observed in some cases of BPH and in some normal epithelia of the gland (not shown).
Thus, only slight PB2 cytoplasmic staining was apparent in the 737 or 738 mutants, while mutants KNRQ and 8/K had similar concentrations of PB2 in the nucleus and the cytoplasm.
Slight patchy mercury staining was present in the dorsal motor nucleus of the vagus nerve.
Tumor cells were considered positive for GLUT-1 expression whenever an even slight netlike membrane staining was present regardless of the degree of the cytoplasmic staining pattern.
The marked nuclear staining of PTEN and slight cytoplasmic staining were observed.
COX-1 staining was slight (weak positive in some cats and negative others) in the afferent arteriole and glomeruli in normal kidneys.
Implanted tissue in the PMP-1 model was negative for CK7 expression and only slight (<10%) membranous staining was seen in two of the murine passages, whereas the PMP-2 model exhibited high membranous CK7 expression in all examined sections.
