In vitro analysis of the binding affinity of ellipsoidal polymersomes to the model target tissue in a flow chamber. a) The experimental setup of a flow chamber designed to evaluate binding affinity of polymersomes to bone marrow stromal cells sheets. The polymersomes encapsulated with fluorophores were added to media that flowed at a rate of 200 ml/h. b) Confocal microphotographs of bone marrow stromal cells exposed to fluorescent polymersomes modified with varying degree of substitution for poly(ethylene glycol) (DSPEG) and degree of substation for RGD peptides (DSRGD). (c) Quantitative analysis of the effects of DSPEG and DSRGD on the number of polymersomes adhered to bone marrow stromal cell sheets. Reproduced with permission.[68]
