Second, it is not possible to distinguish weak ubiquitous staining from strong staining in a small subset of cells using whole-embryo microarray data.
This contrasted with a lack of staining in ovarian vessels, except weak nuclear staining of endothelial cells (arrowhead, Fig.
Serous ovarian tumours are generally consistent and strong expressors of the antigen whereas mucinous tumours may show no or only weak staining.
Control individuals show weak staining in the apical region of the enterocytes thereby showing an uptake of PT-gliadin.
Thre is only weak staining in the enterocytes after the instillation was terminated, indicating an intracellular clearance.
Specimens from patients with non-specific focal fibrosis (group C) usually showed weak focal staining in a few epithelial and endothelial cells (fig 2, panel E).
By contrast, only weak and infrequent staining was seen in group C or normal control lungs, a finding that is consistent with our previous results.
Prostate cancer cells generally have variable or weak staining for PSA, due to the disruption of their normal functioning.
The tissue showed some weak staining that could indicate that the disease is present, he said, but the staining pattern was not typical.
Such occasionally observed differentiation of cytotrophoblast cells was associated with weak cytoplasmic staining of the syncytium.
