Fig. 4. Changes in serum CK level following WJ-MSC administration. Serum CK levels were measured from baseline to week 12 post-WJ-MSC administration. Although the CK levels increased rapidly at the time of SARS-CoV-2 infection in some subjects, all data were included in the analysis. Measurements at a specific time point are marked with a circle, triangle, or diamond. The group average is presented as a bar graph. No statistical difference was observed. CK, creatine kinase; WJ-MSC, Wharton’s jelly-derived mesenchymal stem cell.
