Amyloid Deposition in Transplanted Human Pancreatic Islets: A Conceivable Cause of Their Long-Term Failure
Figure 2
Electron micrograph of human islets transplanted under the kidney
capsule of an alloxan-diabetic athymic nude mouse four weeks after
implantation. Note the extensive degranulation, the abundant endoplasmic
reticulum (star), glycogen particles (black arrows), and swollen mitochondria
(white arrow).
