We have investigated the effects of Pro-Met-Asp-Phe-NH2 (PMAP) on insulin and glucagon release from human fetal pancreatic microfragments in vitro. Four batches of precultured microfragments were incubated for 24 hrs in medium containing 5.5 mM glucose, 17 mM glucose, 1 microM PMAP or 1 microM PMAP plus 17 mM glucose. PMAP significantly enhanced both basal(More)
We have utilized primary cultures of free-floating clusters obtained from pancreata of human cadaveric fetuses. Clusters have been incubated for 10 days in RPMI-1640 medium with 3H-thymidine and various concentrations of fetal calf serum and glucose. Viability of clusters was assessed by insulin radioimmunoassay. Cell reproduction was investigated by(More)
The line of human embryo fibroblasts transformed by Rous sarcoma virus (strain Schmidt-Ruppin) contained and produced Rous sarcoma virus; this was shown by the complement fixation test, immunofluorescent test, electron microscopy and labelling with 3H-uridine peak in sucrose gradient. Biological properties of the new synthesized virus differed from that of(More)
A stable tumorigenic cell line has been obtained from the human hypernephrome. The culture grew as monolayers of large polygonal cells with foamy cytoplasm and 1-2 nucleoli. The cells formed monolayer after the third day after planting into flask and then formed multilayered growth. The electron microscopic studies of hypernephrome sections revealed the(More)
Under in vitro cultivation of 14 soft tissue malignant human tumors there were obtained two cell lines: from cells of hypernephroma (Hn-7) and malignant paraganglioma (Par-1). The transfer of the cultured Par-1 cells medium to recipient cells CET enabled obtaining the transformed cell line 63. This line possesses all the features of in vitro growing tumor(More)
In embryonal cells of mice and hamsters growing in vitro after Rous virus adsorption on them and long before the onset of cell transformation of the virus was detected in thr form closely associated with cells. After exposure of mammalian cells to actinomycin D or after lowering the temperature of their incubation up to +20 degrees C the cell associated(More)
