Single-cell RNA sequencing of bone marrow cells and spleen isolated from mice after sham surgery or myocardial infarction, followed by treatments (vehicle/4-oxo-RA)

Study of the impact of 4-oxo-RA on LSK (bone marrow and spleen) cell characteristics post-myocardial infarction in C57BL/6J mice. Myocardial infarction was induced in female C57BL/6J mice (aged 6 to approximately 12 weeks) through LAD occlusion. Post-surgery, mice were intraperitoneally injected with 30 mg/kg 4-oxo-RA (MI+4-oxo-RA) or the equivalent DMSO in PBS (MI+vehicle) on the 1st and 2nd days after MI. Three days post-MI, mice were euthanized. ScRNA-seq was performed on 25k LSK cells (Lin-, Sca1+, c-Kit+) that were facs sorted.
