Low revascularization of human islets when experimentally transplanted into the liver

J Lau, PO Carlsson - Transplantation, 2009 - journals.lww.com
Previously, we have found that human islets experimentally transplanted beneath the kidney
capsule have lower vascular density than native islets. This study aimed to investigate …

Time course and quantification of pancreatic islet revasculariztion following intraportal transplantation

GL Jones, MT Juszczak, SJ Hughes… - Cell …, 2007 - journals.sagepub.com
A large proportion of islets are lost after transplantation partly due to a lack of functional
vasculature. Islets revascularize from host tissue but the process takes up to 2 weeks and …

Size-dependent revascularization of transplanted pancreatic islets

C Kampf, G Mattsson, PO Carlsson - 2006 - journals.sagepub.com
For their survival and optimal function, pancreatic islets depend posttransplantation on a
rapid and adequate revascularization. Native islets display a marked size-dependent …

R Melzi, F Sanvito, A Mercalli, K Andralojc… - Cell …, 2008 - journals.sagepub.com
Although in a clinical setting islet transplantation is normally performed by percutaneous
intrahepatic infusion, the kidney capsule has been the site of choice in nearly all the studies …

[HTML][HTML] Rapid restoration of vascularity and oxygenation in mouse and human islets transplanted to omentum may contribute to their superior function compared to …

D Espes, J Lau, M Quach, S Ullsten… - American Journal of …, 2016 - Elsevier
Transplantation of islets into the liver confers several site-specific challenges, including a
delayed vascularization and prevailing hypoxia. The greater omentum has in several …

The endothelial cells in islets of langerhans

G Mattsson - Upsala journal of medical sciences, 2005 - Taylor & Francis
The blood vessels of the pancreatic islets are of crucial importance for oxygen and
metabolite supply, and dispersal of secreted hormones. In addition to this, endothelial cells …

Impaired revascularization of transplanted mouse pancreatic islets is chronic and glucose-independent1

G Mattsson, L Jansson, A Nordin, PO Carlsson - Transplantation, 2003 - journals.lww.com
Background. Pancreatic islets are avascular immediately after transplantation and depend
on revascularization. Recently, the authors found decreased vascular density in mouse …

Angiostatic factors normally restrict islet endothelial cell proliferation and migration: implications for islet transplantation

Å Johansson, J Olerud, M Johansson… - Transplant …, 2009 - Wiley Online Library
New blood vessel formation in transplanted islets occurs within 7–14 days post‐
transplantation through both the expansion of donor islet endothelium and ingrowth of blood …

Decreased vascular density in mouse pancreatic islets after transplantation

G Mattsson, L Jansson, PO Carlsson - Diabetes, 2002 - Am Diabetes Assoc
An adequate revascularization is crucial for islet survival and function after transplantation.
Previous studies have suggested that islet revascularization is concluded within 14 days …

Exocrine contamination of isolated islets of LANGERHANS deteriorates the process of revascularization after free TRANSPLANTATION1
