Scaffold fiber diameter histograms for pre-seeded PGA:PLLA scaffold (a), PRI (b), and POI (c) specimens. At both PRI and POI time points, PGA diameters remain fairly constant while PLLA diameter peaks broaden. This is most likely the result of tissue contraction around PLLA and resultant erroneous segmentation; this is especially evident with the double peak in the POI specimen.
