From: Ultrastructural study confirms the formation of single and heterotypic syncytial cells in bronchoalveolar fluids of COVID-19 patients

Fig. 1

Syncytial cells generated from the homotypic fusion of type II pneumocytes of COVID-19 patients in the moderate stage of the disease (between 9–16 days after the first symptoms). (A) The multinucleated dense nucleated and vacuolar cells cytoplasm confirms the type II pneumocytes under PAP imaging. (B) The complete membrane fusion of type II pneumocytes (two) with moderate immunofluorescence using SARS-CoV-2 spike protein-specific primary antibody indicates the presence of the virus. (C) The SEM image (surface ultrastructure) of type II pneumocytes showed small microvilli-like structure, characteristics of type-II pneumocytes. N, nucleus; white arrow, SARS-CoV-2 virus; orange arrow, microvilli.
