Abstract

The composition of the culture medium affects the viability and developmental competency of porcine embryos produced in vitro. Previous transcriptional profiling has identified areas of improvement in the formulation of these media. Xenobiotic metabolism-related genes were upregulated in in vitro-cultured porcine embryos compared to their in vivo-derived counterparts, and the antibiotic gentamicin is a component of porcine embryo culture media. While effective against a broad spectrum of bacteria, gentamicin has been observed to be toxic to rat embryos and may induce changes in gene expression in cell culture. The objective of this study was to determine if gentamicin has an adverse effect on the development of porcine embryos. After in vitro fertilization, presumptive zygotes were placed in either MU4 medium containing gentamicin or MU4 medium without gentamicin. No difference was detected in blastocyst development, total cell number, apoptotic index, or expression of 3 selected genes between embryos cultured with or without gentamicin (p > 0.05). Therefore, porcine embryos are able to tolerate the presence of 10 μg/mL gentamicin without significant impacts on blastocyst development rate, total cell number, or apoptosis.

期刊介绍： Molecular Reproduction and Development takes an integrated, systems-biology approach to understand the dynamic continuum of cellular, reproductive, and developmental processes. This journal fosters dialogue among diverse disciplines through primary research communications and educational forums, with the philosophy that fundamental findings within the life sciences result from a convergence of disciplines. Increasingly, readers of the Journal need to be informed of diverse, yet integrated, topics impinging on their areas of interest. This requires an expansion in thinking towards non-traditional, interdisciplinary experimental design and data analysis.
