Mast cell tryptases induce an increase of angiogenesis in chicken chorioallantoic membrane.

<p>When compared to the control CAM (no tryptases), CAM incubated in presence of rmMCP-6 and 7 showed an increase in the number of blood vessels. Moreover, an increase in blood vessel caliber was also seen in the presence of the tryptases. The graph shows the number of vessel per field (6.5mm²) from each sample.
