Comparison of different culture conditions for human mesenchymal stromal cells for clinical stem cell therapy

Objective. Mesenchymal stromal cells (MSCs) from adult bone marrow (BM) are considered potential candidates for therapeutic neovascularization in cardiovascular disease. When implementing results from animal trials in clinical treatment, it is essential to isolate and expand the MSCs under conditions following good manufacturing practice (GMP). The aims of the study were first to establish culture conditions following GMP quality demands for human MSC expansion and differentiation for use in clinical trials, and second to compare these MSCs with MSCs derived from culture in four media commonly used for MSC cultivation in animal studies simulating clinical stem cell therapy. Material and methods. Human mononuclear cells (MNCs) were isolated from BM aspirates by density gradient centrifugation and cultivated in a GMP‐accepted medium (EMEA medium) or in one of four other media. Results. FACS analysis showed that the plastic‐adherent MSCs cultured in EMEA medium or in the other four media were identically neg...
