Cell-cell contact interactions conditionally determine suppression and selection of the neoplastic phenotype.

Separation of chemical and physical carcinogenesis into the stages of initiation (mutation) and promotion (selection) established that incipient neoplastic cells could persist in the organism indefinitely without expression. Spontaneous mutations associated with cancer also lie dormant in untreated normal tissue. Without selection, there is no tumor development. Experiments in cell culture show...

Suppression of the transformed phenotype in somatic cell hybrids.

Somatic cell hybrids between mouse mammary tumour cells (TA3B) and diploid rat embryo fibroblasts (REF) or between TA3B and Syrian hamster sarcoma cells (BI) were examined for the in vitro characteristics of transformed cells as soon as possible after cell fusion. Unlike the parental tumour cells as three of four TA3B X REF and five BI X TA3B independent hybrid lines had low colony-forming effi...

WT1-interacting protein (Wtip) regulates podocyte phenotype by cell-cell and cell-matrix contact reorganization.

Podocytes respond to environmental cues by remodeling their slit diaphragms and cell-matrix adhesive junctions. Wt1-interacting protein (Wtip), an Ajuba family LIM domain scaffold protein expressed in the podocyte, coordinates cell adhesion changes and transcriptional responses to regulate podocyte phenotypic plasticity. We evaluated effects of Wtip on podocyte cell-cell and cell-matrix contact...

We have contact: endothelial cell-smooth muscle cell interactions.

Blood vessels are composed of two primary cell types, endothelial cells and smooth muscle cells, each providing a unique contribution to vessel function. Signaling between these two cell types is essential for maintaining tone in mature vessels, and their communication is critical during development, and for repair and remodeling associated with blood vessel growth. This review will highlight t...

Transmitter-receptor interactions between growth cones of identified Lymnaea neurons determine target cell selection in vitro.

In addition to their involvement in transsynaptic communication in the adult nervous system, neurotransmitters also participate in many developmental events, such as neurite initiation and outgrowth. Although growth cones can release transmitters and are themselves sensitive to exogenously applied neurotransmitters, a direct causal relationship between the release of transmitter from one growth...
