Maternal age affects D8 embryo gene expression both in trophoblast and inner cell


ABSTRACT: The aim of the study was to compare the effects of maternal age on embryos in horses. For that, 11 embryos were collected at 8 days post ovulation (expanded blastocyst stage) from 2 groups of multiparous mares of different age: 5 from young mares (<10 years old) and 6 from old mares (10-17 years old). Embryos collected were cut in 2 parts: one hemi-embryo containing pure trophoblast and the other one containing trophoblast + inner cell mass. ARN extractions were performed for all samples using PicoPure RNA isolation kit (Applied Biosystem). Five nanograms of both parts of each embryo were sequenced in paired-end with a length of 30-50bp separately using Illumina NextSeq 500 High. Data were trimmed using Cutadapt. Sequences with less than 10bp were removed.
