Modulation of Adipose-Derived Mesenchymal Stem/Stromal Cell Transcriptome by G-CSF Stimulation

Figure 1

Characterization of ADSC and stimulation with rhG-CSF. (a) ADSC immunophenotypic assessment as positive for CD73, CD90, and CD105 and negative for CD34 and CD45. (b) Osteogenic differentiation of ADSCs after 14–21 days of induction, assessed by alkaline phosphatase (Alk. Phos.) and von Kossa stainings, showing adequate mineralization of the ECM. (c) Cell viability assessed through 7AAD assay analyzed at 8, 24, and 48 h, showing no toxicity with either formulation at both doses. (d, e) ADSC stimulation with both formulations at 200 ng/ml, showing CD90 expression unaltered during the same time period (d), while CD44 was significantly reduced as early as 8 hours post stimulation. when compared to time 0 for each condition.
