A novel prespore-cell-inducing factor in Dictyostelium discoideum induces cell division of prespore cells.
In Dictyostelium discoideum strain V12M2, at a very low cell density (approximately 10(2) cells/cm2), most amoebae differentiate into prespore cells in a salt solution containing cAMP if an adequately diluted conditioned medium (CM) is provided (Oohata, A. A. (1995) Differentiation 59, 283-288). This finding suggests the presence of factor(s) released into the medium that are involved in induci...
متن کاملMacrocyst development in Dictyostelium discoideum. III. Cell-fusion inducing factor secreted by giant cells.
A factor was discovered that markedly enhances the degree of fusion activity between cells of the opposite mating-type strains, MI1 and NC4, in the sexual cycle of Dictyostelium discoideum. This factor, designated cell-fusion inducing factor (CFIF), was detected initially in supernatants taken from 24 h dark-grown mixed cultures of HM1 and NC4 cells, and subsequently shown to be secreted by gia...
متن کاملChromatin structure in the cellular slime mold Dictyostelium discoideum.
The structure of Dictyostelium discoideum chromatin has been studied by the following techniques: electron microscopy, staphylococcal nuclease digestion, acrylamide gel electrophoresis, sucrose gradient centrifugation, and melting. The basic unit of chromatin is the nucleosome, which is a particle 98.6 A in diameter. Approximately 50% of the chromatin is protected from nuclease digestion, but t...
متن کاملCell Fusion in the Cellular Slime Mold, Dictyostelium Discoideum
The myxamebae of the cellular slime mold feed upon bacteria and multiply by fission. As soon as the food supply is exhausted fission ceases. They aggregate and form migrating pseudoplasmodia, then fruit (Bonner, 1959). Huffman and Olive (1964) reported that in Dwtyostehum &s~oideum some cell fusions were observed at tile very early aggregation stages, but they observed no fusion at later stages...
متن کاملCell cycle phase, cellular Ca2+ and development in Dictyostelium discoideum.
In Dictyostelium discoideum, the initial differentiation of cells is regulated by the phase of the cell cycle at starvation. Cells in S and early G2 (or with a low DNA content) have relatively high levels of cellular Ca2+ and display a prestalk tendency after starvation, whereas cells in mid to late G2 (or with a high DNA content) have relatively low levels of Ca2+ and display a prespore tenden...
