Precise printing of spheroids

Biologist at Penn State have developed a new means of printing cells on scaffolds that results in greater precision for tissue regeneration.   “The researchers were able to create a matrix of spheroids with capillary sprouting in the desired directions. Capillaries are necessary for creation of tissues that can grow and continue to live. They are a means of delivering oxygen and nutrients to the cells, without which, cells will die. Without capillaries, only the outermost cells will receive oxygen and nutrients.”   MORE
