Allogeneic islet cells implant on poly-l-lactide matrix to reduce hyperglycaemia in streptozotocin-induced diabetic rat

0 views | Oct 22 2018

Hendrawan S et al. indicated the islet cell matrix implant reduced the blood glucose levels although complete normo-glycaemia was not established. The islet cell matrix implant may serve as an additional option for islet cell transplantation using 3D scaffold platforms for better survival and function of the islet cells. [Read the Full Post]
