Figure 4. Biological effects of dual magnetic stem cell labelling.

Figure 4

(a) Apoptosis detection in dual magnetically labelled and unlabelled stem cells, assessed by the TUNEL assay, shows no difference in staining. (b) Cell viability of dual magnetically labelled and unlabelled cells, 24 h post labelling, assessed by Trypan Blue assay, show no significant difference between the cells (n = 3). (c) Cell proliferation rates of dual magnetically labelled and unlabelled cells, 10 days post labelling, assessed by MTT assay, show no significant difference between the cells (n = 3). (d) Multi-lineage differentiation of dual magnetically labelled and unlabelled cells shows no difference in adipogenesis induction (Oil Red O staining); osteogenesis induction (Alizarin Red S staining); or chondrogenesis induction (Alcian Blue staining).
