Assessing the potential role of copper and cobalt in stimulating angiogenesis for tissue regeneration

The use of copper (Cu2+) and cobalt (Co2+) has been described to stimulate blood vessel formation, a key process for the success of tissue regeneration. However, understanding how different concentrations of these ions affect cellular response is important to design scaffolds for their delivery to b...
