## Abstract

Human interference reduces wild felid populations. Somatic cell nuclear transfer and the use of induced pluripotent stem cells are potential conservation strategies. To improve the efficiency of these strategies, it is essential to establish adequate protocols for the synchronization of cells in the G0/G1 phase of the cell cycle. Cell cycle synchronization can arrest cell cycle progression by inhibiting factors involved in cell duplication. However, this step varies among wild felids and has not been successful in some species. In addition, the effect of this step on cell applications remains unclear. Therefore, this review highlights the primary differences among wild felids that can cause this variability, the most promising results, and the methods used. Finally, the importance of cell cycle synchronization in biotechnologies involving the nuclear reprogramming of somatic cells in wild felid conservation is highlighted.
