Stages of in vitro angiogenesis.

The course of angiogenesis is shown for native groups (N₁, N₂), control groups (SCR₁, SCR₂) and knockdown groups (sh₁, sh₂) during a cultivation period of 50 days. Mean values are calculated for 4 visual fields of 4 wells per culture at each detection day. Native and control groups of both batches ran through all six stages of angiogenesis chronologically. Infected cells of sh₁ and sh₂ did not precede to further stages than stage 3.
