The loss of epithelial differentiation in carcinomas, which is accompanied by higher mobility and invasiveness of the tumour cells, is often a consequence of reduced intercellular adhesion. The primary cause of the "scattering" of cells in invasive carcino ...
The loss of epithelial differentiation in carcinomas, which is accompanied by increased mobility and invasiveness of the tumour cells, is often a consequence of reduced intercellular adhesion. Recent reports have indicated that the primary cause for the 's ...
The use of dyes has been helpful for the photodiagnosis of small cancers accessible to endoscopic examn. An important limiting factor of this technol. is that the presently used fluorescent dye mixt. has a relatively poor capacity to accumulate preferentia ...
To improve the detectability of tumors by light-induced fluorescence, the use of monoclonal antibodies (MoAb) as carriers of fluorescent molecules was studied. As a model for this approach, the biodistribution of an anticarcinoembryonic antigen (CEA) MoAb ...
The type beta transforming growth factors (TGF) are potent regulators of the growth and functions of lymphocytes and macrophages. Recently the human glioblastoma cell line 308 was shown to produce TGF-beta 2. The relevance of this finding was evaluated fur ...
