A Primary Role for α-Cells as Amino Acid Sensors.

abstract：OBJECTIVE:Insufficient development of a new intra-islet capillary network after transplantation may be one contributing factor to the failure of islet grafts in clinical transplantation. The present study tested the hypothesis that the angiostatic factor thrombospondin-1 (TSP-1), which is normally present in islets, re...
