Chest computerized tomography (CT) images of the COVID-19 patient. A-1A-4 On February 12, ground-glass opacity (GGO) and pneumonia infiltration occurred in both the left and right lungs. Several GGO regions in each of the 5 lung lobes, and some with traction bronchiectasis; in the left lower lobe, crazy-paving pattern (GGO with superimposed inter- and intralobular septal thickening) with a few scattered consolidation and vascular dilatation were observed. B-1B-4 CT images on February 22 indicate the symptoms of the patient are slightly relieved, but the pneumonia was still significant. There were reduced regions of initial GGO, with a new area of subpleural consolidation. C-1C-4 Cell transplantation was performed on February 24. On March 1, the pneumonia infiltration faded away very much. Most of the ground-glass opacity lightened, or even disappeared. The partial area of consolidation was still observed
