Induction of synchronous cell division in mass cultures of Tetrahymena piriformis.
Abstract This preliminary report shows that, using intermittent heat treatment of mass cultures of Tetrahymena, 85 per cent of the cells can be induced to undergo division simultaneously. ThreeExpand

DNA synthesis, phosphate content and growth in mass and volume in synchronously dividing cells.
Abstract Mass cultures of Tetrahymena pyriformis GL were synchronized by the method of Scherbaum and Zeuthen. In various phases of synchronized population growth, cell volume and dry weight wereExpand

Morphogenetic events in normal and synchronously dividing Tetrahymena.
Synchronous cell-division has been induced in mass cultures of the small ciliated protozoan Tetrahymena pyriformis (Scherbaum & Zeuthen, 1954). While it is known that cells grow in a characteristicExpand

TLDR
In the past five years elaborate methods have been devised for the in­ duction of synchronous multiplication in mass cultures of bacteria, protozoa, algae, and cancer cells. Expand

A Comparison of Synchronized Cell Division in Protozoa
SYNOPSIS. From an equation derived for measuring synchrony in microbial systems, a synchronization index (SI) may be computed, which depends on 3 parameters: (1) fraction of the population undergoingExpand

ULTRASTRUCTURE OF MUCOCYSTS AND PELLICLE OF TETRAHYMENA PYRIFORMIS
Tetrahymena pyriformis GL was fixed with glutaraldehyde and/or OsO4 for a study of cytoplasmic ultrastructure. Many small vacuoles 0.05 to 0.5 µ in diameter were found to contain each a denseExpand

A rapid radioassay technique for cellular suspensions.
Abstract A simplified technique for studying in vivo the uptake of labeled precursors into proteins and nucleic acids of microorganisms is presented. Applications to studies in protozoan andExpand
