This study provides useful datasets on gene expression and chromatin accessibility profiles in spermatogonial cells at different postnatal ages in mice. Overall, the technical aspects of the sequencing analyses and computational/bioinformatics are solid. However, there are concerns with the identity of the isolated cells and the lack of acknowledgment for previous studies that have also performed ATAC-sequencing on spermatogonia of mouse and human testes. The limitations call into question the validity of the interpretations and reduce the potential merit of the findings.
