Fig. 1From: Identification and validation of multiple cell surface markers of clinical-grade adipose-derived mesenchymal stromal cells as novel release criteria for good manufacturing practice-compliant productionTraditional phenotyping of clinical-grade adipose-derived mesenchymal stromal cells (AMSCs) expanded in human platelet lysate. a Clinical-grade AMSCs grown in human platelet lysate were expanded ex vivo and immunophenotyped using flow cytometry according to the release criteria presented in this table. b Representative flow cytometry scatter plots show AMSCs are a homogeneous population of cells and exhibit surface expression of standard cell surface markers, including CD105, CD44, CD73, and CD90, and are negative for HLA-DR. c Analysis of the flow cytometry release criteria across clinical-grade AMSCs from 15 donors demonstrated minimal variability in the population frequency (% Gated) of the surface markers. All AMSC donor cells were >85Â % positive for CD90, CD105, CD73, CD44, and HLA-ABC, and were <85Â % positive for HLA-DR, CD45, and CD14Back to article page
