Abstract

One of the most important factors determining the success of the development of cloned embryos is the cell cycle stage of the donor cells. We investigated the effects of serum starvation, culturing to confluence and roscovitine treatment on the cell cycle synchronization of goldfish caudal fin-derived fibroblasts by flow cytometric analysis. The results show that culturing the cells to confluence (85.5%) and roscovitine treatment (82.71%) yield a significantly higher percentage of cells arrested in the G0/G1 (P<0.05) phase than serum starvation (62.85%). Different concentrations of roscovitine (5, 10, or 15μM) induce cell cycle arrest at the G0/G1 phase.


Key words: Cell cycle synchronization, G0/G1 phase, Goldfish, Serum starvation, Culture to confluence, Roscovitine.
