Fig 5. Release and bioactivity of rhFGF2.

Fig 5

A Cumulative release from delivery discs. The amount of released rhFGF2 determined by ELISA. Data is presented as mean ± SD, n = 5. B Addition of rhFGF2-loaded discs (white) to CAMs led to increased blood vessel formation compared to control experiments (gray). Data is presented as mean ± SD, n = 4. C Exemplar pictures of the CAM assay. Left: Control discs without rhFGF2 induce no specific blood vessel formation. Right: rhFGF2-loaded discs lead to blood vessel formation (white arrows) towards the delivery disc. Insets: magnification of 2.2 x. All scale bars equal 2 mm.
