A Role for CD154, the CD40 Ligand, in Granulomatous Inflammation

Figure 4

Absorbable suture bundles undergo a rapid bioresorption between weeks 8 and 10 postimplantation. (a) Tissue sections (low and high magnifications, scale bars 500 and 50 μm for left and right panels, resp.) were obtained at week intervals and stained with Masson’s trichrome. Microphotographs shown correspond to a representative kinetic of 3 experiments performed. Bundle contours showing rapid shrinking by week 8 are indicated by arrowheads. Red arrows indicate the nonabsorbable thread which, upon section by the microtome, creates an artefactual void on the tissue section (asterisk); (b) quantification of (a) suture bundle bioresorption.
