Repeated Induced-Membrane Technique Failure without Infection: A Series of Three Consecutive Procedures Performed for a Single Femur Defect

Figure 4

Histological sections of induced membranes from P1 (a), P2 (b), and P3 (c). After 4% paraformaldehyde fixation, membrane fragments were embedded in paraffin and then sections were cut and processed for routine hematoxylin-eosin-saffron staining. Magnification 20x. . The black star indicates the poly-methyl-methacrylate location before its removal. Fibroblast density is shown in (d) (mean number of fibroblasts per of the mean from 3 different slides for each considered membrane). Plastic-adherent mesenchymal stromal cells were isolated according to the explant culture method (e); P2 membrane) and then characterized by flow cytometry according to their phenotypic profile: CD90+, CD73+, CD105+, and CD45- (f).
