Тезаурус:
- Previous in vitro attempts to investigate the role of thymic stromal cells in T-cell development have been hampered by the limited ability of monolayer cultures to support a full programme of T-cell maturation and by the difficulty of obtaining cultures of thymic epithelial cells that maintain their in vivo phenotype.
- In coeliac disease, patients with abnormal histology have increased intensity of epithelial staining which in some cases now extended into the crypts.
- The alternative mode of transmission is through gap junctions as described in ciliated epithelial cells of the lung or in glial cell populations both in vitro and in situ .
- When extracts from the HeLa cervical epithelial cell line were used in this assay we observed two complexes as in our previous experiments (Figure 2b).
- Increased cellular proliferation has previously been reported in Barrett's mucosa, and it is interesting to note that EGF is found in many of the epithelial cells of Barrett's epithelium.
- This was despite the fact that out patients had the expected increases in intra epithelial lymphocyte count, as well as increased expression of epithelial class II major histocompatibility complex antigens.
- The requirement for mesenchymal support can be mapped to the initial stages of intrathymic development because the later stages of maturation, from double-positive CD4 + CD8 + thymocytes into single-positive CD4 + or CD8 + cells, can be supported by epithelial cells alone.
- In these cases, the nodules may represent passive clumping of non-proliferating endocrine cells in glands in which the non-endocrine epithelial cells have disappeared.
- Class II major histocompatibility complex antigen could be detected on the epithelial cells of all control cases.
- The best characterised is epithelial cadherin, E-cadherin or uvomorulin.
- RNA in situ hybridization was used to demonstrate that the CFTR expression plasmid can be delivered to airway epithelial cells by liposome-mediated transfection in vivo.
- Significant but heterogeneous increases werefound in urokinase type plasminogen activator concentrations of biopsy specimens originating from carcinomas of both epithelial cell types.
- We report here that the development of TCR - CD4 - CD8 - T-cell precursors into TCR + cells expressing CD4 and/or CD8 requires the presence of both major histocompatibility complex class II + epithelial cells and fetal mesenchyme.
