In vitro cultivation of human islets from expanded ductal tissue

…, KH Song, A Sharma, JJ O'Neil - Proceedings of the …, 2000 - National Acad Sciences
A major obstacle to successful islet transplantation for both type 1 and 2 diabetes is an
inadequate supply of insulin-producing tissue. This need for transplantable human islets has …

Maturation of human embryonic stem cell–derived pancreatic progenitors into functional islets capable of treating pre-existing diabetes in mice

…, J Xu, R Gauvin, K Narayan, F Karanu, JJ O'Neil… - Diabetes, 2012 - Am Diabetes Assoc
Diabetes is a chronic debilitating disease that results from insufficient production of insulin

Both the Lyt-2+ and L3T4+ T cell subsets are required for the transfer of diabetes in nonobese diabetic mice.

BJ Miller, MC Appel, JJ O'neil… - Journal of immunology …, 1988 - journals.aai.org
The nonobese diabetic mouse is a model of spontaneous type I diabetes mellitus. It is
possible to induce diabetes in young, irradiated nonobese diabetic mice by using adoptive …

Complete protection of islets against allorejection and autoimmunity by a simple barium-alginate membrane

VF Duvivier-Kali, A Omer, RJ Parent, JJ O'Neil… - Diabetes, 2001 - Am Diabetes Assoc
We describe a new technique for microencapsulation with high–mannuronic acid (high-M)
alginate crosslinked with BaCl 2 without a traditional permselective component, which allows …

Enrichment of human embryonic stem cell-derived NKX6. 1-expressing pancreatic progenitor cells accelerates the maturation of insulin-secreting cells in vivo

Human embryonic stem cells (hESCs) are considered a potential alternative to cadaveric
islets as a source of transplantable cells for treating patients with diabetes. We previously …

Maturation and function of human embryonic stem cell-derived pancreatic progenitors in macroencapsulation devices following transplant into mice

…, A Rezania, J Xu, K Narayan, JK Fox, JJ O'Neil… - Diabetologia, 2013 - Springer
Aims/hypothesis Islet transplantation is a promising cell therapy for patients with diabetes,
but it is currently limited by the reliance upon cadaveric donor tissue. We previously …

Distinct effects of STAT5 activation on CD4+ and CD8+ T cell homeostasis: development of CD4+ CD25+ regulatory T cells versus CD8+ memory T cells

MA Burchill, CA Goetz, M Prlic, JJ O'Neil… - The Journal of …, 2003 - journals.aai.org
Using transgenic mice that express a constitutively active version of STAT5b, we demonstrate
that STAT5 plays a key role in governing B cell development and T cell homeostasis. …

[HTML][HTML] Long-term survival of nonhuman primate islets implanted in an omental pouch on a biodegradable scaffold

DM Bermana, JJ O'Neil, LCK Coffey… - American Journal of …, 2009 - Elsevier
The aim of this study was to test whether an omental pouch can be used as an alternative
site for islet implantation in diabetic monkeys. Here we report the successful engraftment of …
