Scriptaid Improves Cashmere Goat Embryo Reprogramming by Affecting Donor Cell Pluripotency Molecule NANOG Expression

Year: 2025

Abstract: Currently, the efficiency of somatic cell nuclear transfer (SCNT) technology is relatively low, primarily owing to reprogramming abnormalities in donor cells or reconstructed embryos. Using histone deacetylase inhibitor (HDACi) to artificially alter the epigenetic modifications of donor cells and improve the reprogramming ability of reconstructed embryos is effective in improving nuclear transfer efficiency. In this study, we used Albas cashmere goat cells as donor cells, treated them with Scriptaid, and constructed embryos using SCNT. The results suggest that donor cell treatment with Scriptaid significantly increased the cellular histone acetylation modification level, perturbed the expression of the pluripotency molecule NANOG, altered the reprogramming ability of embryos, and increased the developmental rate of SCNT-reconstructed embryos. Scriptaid inhibited donor cell proliferation, induced apoptosis, and blocked the G0/G1 phase of the cell cycle. These results provide a new research direction for improving SCNT efficiency and a new perspective in the fields of regenerative medicine, agriculture, and animal husbandry.
