Fig. 1From: Manufacturing, quality control, and GLP-grade preclinical study of nebulized allogenic adipose mesenchymal stromal cells-derived extracellular vesiclesEV characteristics were stable across multiple lots of haMSC-EVs. A Representative images of haMSC-EVs at different scales. B Size distribution of 5 lots of haMSC-EVs analyzed via NTA. C Representative images of the Western blot results for haMSC-EVs and parental cells. The haMSC-EVs were CD9-, CD63-, CD81-, and HSP70-positive and CANX-negative. Full-length blots are presented in Additional file 2: Fig. S1. D Marker expression ratios analyzed with nanoflow cytometryBack to article page
