Blood Vessel Networks
A new mathematical model accurately describes the formation of blood
vessel networks, potentially providing a better understanding of vascular
networks in living creatures as well as the pathological blood vessel
formation that often accompanies certain cancers and other ailments.
These images depict the structures that cells form on a growing medium
for various initial cell densities, which are consistent with the new
model's predictions. Image (a) shows the disconnected patterns that
arise when the initial density is only 50 cells/square millimeter. The
subsequent images show networks arise as the starting cell density is
increased to (b) 100 cells/square millimeter, (c) 200 cells/square millimeter,
and (d) 400 cells/square millimeter.
