| Description |
Round spermatid injection (ROSI) technique holds great promise for clinical treatment of infertile men who were diagnosed as that round spermatids are the most mature germ cells. However, the mechanisms underlying the poor developmental potential of both human and mouse ROSI embryos and how to overcome it remains largely unknown. Here, we establish the gene expression, chromatin accessibility and DNA methylation landscapes of mouse ROSI embryos using a single-cell multi-omics approach. Comparative analysis reveals the molecular reprogramming barriers marked by these three layer profiling abnormalities in ROSI embryos despite successful reprogramming globally. Remarkably, we screen out a novel small compound-A366 that can increase the rate of ROSI embryos to blastocyst stage and healthy pub by about 2 times. Finally, we demonstrate that A366 exerts its roles by partial overcoming of the reprogramming barriers; especially, the treatment of A366 could recover the expression of key genes critical for skeleton and chromatin organization, and the re-distribution of γ-tubulin and morphology of male pronucleus. Collectively, our study unveils the molecular reprogramming barriers inherent to ROSI embryos, and identifies A366 to be a potential small molecule to partially overcome these barriers. |
