FIG. 2.

Histological images of ectopic implants recovered after 2 months and stained with Masson's trichrome showing a high number of blood vessel-like structures in the UC-MSC-seeded scaffold (C) compared with the BM-MSC-seeded scaffold (B) and empty scaffold (A). bv, blood vessel; ft, fibrous tissue; b, bone; (*), blood vessel count. Scale bar=100 μm. (n=4 for both cell-seeded and not seeded scaffold groups). In (D) a quantification of the number of blood vessels present in 2-month implants of the empty scaffold (SK) and BM-MSC and UC-MSC-seeded scaffolds (SK+BM-MSC and SK+UC-MSC) is presented.
