Clonal variation in paramecium. I. Persistent unstable clones.
Clones of Paramecium of identical serotype when cultured in test tubes may differ in their ability to give rise to subclones of this serotype. Characteristically, stable clones yield progeny indistinguishable from their parents, while from unstable clones diverse subclones with new serotypes can be isolated repeatedly. Stable lines are resistant to changes in culture medium and also are unaffec...
متن کاملClonal variation in paramecium. II. A comparison of stable and unstable clones of the same serotype.
Paramecium generally expresses only one antigen on its surface from among an array of antigens. This mutual exclusion of antigens now has been shown in certain instances to be illusory. Unstable clones which will give rise to subclones with new serotypes possess several antigens. Unstable clones, even though they manifest only one serotype, continually manufacture an antigen other than the surf...
متن کاملMicronuclear Variation in Paramecium bursaria
THE dimorphic condition of the nuclear apparatus of the Infusoria is one of the most interesting and characteristic specializations exhibited by the group, apparently representing a segregation of ' somatic' and ' germinal' elements into distinct macronuclei and micronuclei. Accordingly these bodies have been extensively studied during the various life-processes of the Infusoria. Furthermore, s...
متن کاملPersistent Unstable Equilibria in Wonderland
Models of the interactions between population, economy, and environment often contain nonlinear functional relationships and variables that vary a t different speeds. These properties foster apparent unpredictabilities in system behavior. Using a simple deterministic model of demographic, economic and environmental interactions, we illustrate the usefulness of geometric singular perturbation th...
متن کاملPersistent clonal areas and clonal expansion in Barrett's esophagus.
Three patients with Barrett's esophagus who had cytogenetic abnormalities detected in their metaplastic epithelium developed high-grade dysplasia or adenocarcinoma during prospective surveillance over a period of 1.5 to 6 years. In the 3 cases, cytogenetic abnormalities that were associated with the most advanced histological lesions were present in samples obtained 11, 25, and 48 months prior ...
