Implication

In vitro experiment demonstrates that roscovitine and serum starvation fail to improve cell cycle synchronization in manatee somatic cells, suggesting alternative protocols are required.

Key Points

To evaluate the efficacy of roscovitine exposure and serum starvation on G0/G1 phase cell cycle synchronization, viability, and apoptosis in Antillean manatee somatic cells.
Treated somatic cells with 10 µM roscovitine for 12 and 24 hours, or serum starvation (0.5% serum) for 24 hours.
Measured G0/G1 phase synchronization using flow cytometry.
Evaluated cell morphology, viability, and apoptosis using microscopy-based assays.
Neither serum starvation (68.4%) nor roscovitine (12 h: 84.3%; 24 h: 79.3%) increased G0/G1 synchronization relative to control (83.4%).
Serum starvation significantly decreased the proportion of cells in the G0/G1 phase compared to both the control and the 12-hour roscovitine treatment (p < 0.05).
Cell viability and morphology remained statistically unchanged across groups (p > 0.05), but 24-hour roscovitine treatment elevated apoptotic markers relative to control.
