SUMMARY Burkitt somatic cell hybrids (D98/HR-l) synthesize both the A and B forms of glucose 6-phosphate dehydrogenase, which were originally derived from the two fused human cells. The A form is from D98 cells and the B form was supplied by the P3J-HR-l cells. The formation of a heteropolymer of glucose 6-phosphate dehydrogenase in the hybrid proves that a hybrid was obtained. Selection of hyb...

Clonal neuroblastoma X glioma hybrid cells were shown to form synapses with cultured, striated muscle cells. The properties of the synapses between hybrid and muscle cells were similar to those of the normal, neuromuscular synapse at an early stage of development. The number of synapses formed and the efficiency of transmission across synapses were found to be regulated, apparently independentl...

As cells progress through the multistep process of neoplastic transformation, they eventually acquire the property of invasive behavior. Although both plasminogen activators (PA) and their inhibitors (PAI) contribute to this process, their regulation in normal and transformed cells remains poorly defined. Because somatic cell hybrids provide useful tools for examining the transformation pathway...

This Progress Report highlights recent developments in nanostructured organic and hybrid solar cells. The authors discuss novel approaches to control the film morphology in fully organic solar cells and the design of nanostructured hybrid solar cells. The motivation and recent results concerning fabrication and effects on device physics are emphasized. The aim of this review is not to give a su...

although wild safflower (c.oxyacantha, 2n=24) has not been studied to a very large extent, yet it is believed that it can be used as an important source of biotic and abiotic stress resistance genes for improvement of cultivated safflower (c.tinctorius l., 2n=2x=24). in this study, the crossability between these two (cultivated and wild safflower) species was evaluated as based upon morphology ...

When Ehrlich ascites cells were fused with diploid fibroblasts, isolated directly from the animal, the resulting hybrid cells regularly produced progressive tumours. However, an analysis of a range of clonal populations of these hybrid cells, each derived from a separate primary fusion, revealed that the chromosomal constitution of these cells was highly unstable; all cell populations were foun...
