Fig. 2From: HLA-DR expression in clinical-grade bone marrow-derived multipotent mesenchymal stromal cells: a two-site studyAnalysis of cell culture parameters. Effect of cell density on HLA-DR expression was studied in batches released from both manufacturing sites, namely Barcelona (a) and Helsinki (b). However, high dispersion without statistical correlation was observed in both cases (p value = 0.2287 and 0.2272, respectively)Back to article page
