snRNA-seq of mus musculus
DBA/2J and DBA/2J-mdx mice (D2.B10-Dmdmdx/J), hereafter denoted as D2-mdx mice, were purchased from the Jackson Laboratory (JAX ID: 013141; Bar Harbor, ME). All experiments were approved by the Institutional Animal Care and Use Committee in Seoul National University Hospital (#20-0216-S1A0) and animals were maintained in a facility accredited by AAALAC International (#001169) in accordance with the Guide for the Care and Use of Laboratory Animals 8th edition, NRC. Muscle samples were taken from the hindlimb and quadriceps and frozen with liquid nitrogen. snRNA-seq was performed on fresh frozen muscle cells from two male wild-type DBA/2J mice, two male D2-mdx mice, and two male D2-mdx mice treated with deflazacort.
