Figure 5.
Quantification of length and branching number of capillary-like structures observed in fibrin gels. the CD-31 immuno-labelling, length and branching number of the capillary-like structures were measured for conditions using commercially available medium EGM-2MV (EGM-2MV), unconditioned medium (DF medium), medium conditioned during 1 week by dermal fibroblasts under normoxic conditions (DF-Nx), and medium conditioned during 1 week by dermal fibroblasts under hypoxic conditions (DF-Hx). (A) Quantification of the length of the structures. N is the number of observed structures in the central field of 3 distinct gels. The length was expressed as the value provided by ImageJ software. (B) Comparison of the total length of capillary-like structures and their branching number.
