21_47/2009Microfluidics: Surface-Treatment-Induced Three-Dimensional Capillary Morphogenesis in a Microfluidic Platform (Adv. Mater. 47/2009)

The cover shows confocal images of 3D sprouting into matrix material in microfluidic channels. Roger Kamm and co-workers report on p. 4863 that robust induction of realistic angiogenesis into the 3D matrix material under simultaneous imaging and a stably controlled concentration gradient of chemoattractants can be achieved. The formation of a 3D vascular network is demonstrated to be a direct consequence of surface treatment of the region of the device-containing matrix material.
