About This Topic

OBM Transplantation is an international peer-reviewed Open Access journal, which covers all evidence-based scientific studies related to transplantation. This is seeking original manuscripts for a Special Issue on cell-based therapy for diabetes: “Current Advancement of Islet Cell Transplantation in the Treatment of Diabetes mellitus” scheduled to appear in the first half of 2018.

Islet transplantation and pancreas transplantation have been becoming promising therapies for diabetes, which can restore normal blood glucose and prevent diabetes complications. However, there are many grand challenges for maintaining long-term graft function and insulin independence in diabetes patients.

The special issue will provide a forum for presenting current research works and clinical results showing advancement of cell-based therapy for diabetes, including auto-transplantation, all-transplantation, inflammatory reaction involved islet transplantation, islet macro and microencapsulation, stem cell therapy, as well as in vitro and in vivo imaging of the islets. The special issue will also be open to any author, but mainly invited by guest editor. Each submission will be reviewed by at least two reviewers to ensure a very high quality of papers selected for the Special Issue.

Islet Identity in Transplantation Procedures: The Intersection of Cellular Maturity and Function

Received: 08 November 2018;  Published: 05 March 2019;  doi: 10.21926/obm.transplant.1901055

Abstract

Islet transplantation is a promising technique for millions of patients with diabetes, but is severely limited by a shortage of cadaveric donor islets, and more so because of stringent inclusion criteria for organ donation including donor metabolic function, age, and comorbidities. The impact of the [...]

Targeting Acute Islet Inflammation to Preserve Graft Mass and Long-Term Function

Received: 21 November 2018;  Published: 29 January 2019;  doi: 10.21926/obm.transplant.1901043

Abstract

Islet transplantation is a minimally invasive cell based replacement therapy to prevent or reverse diabetes or hypoglycemia through natural hormonal responses to regulate blood glucose. However, extending the islet graft functional lifespan remains a challenge that prevents long-term success and wid [...]

Where’s Waldo? Extrahepatic Site Options for Islet Transplantation

Received: 29 October 2018;  Published: 24 January 2019;  doi: 10.21926/obm.transplant.1901042

Abstract

The current predominant location for allo- and auto-transplantation of islet cells is into the liver via the portal venous system. Despite the relative success of this site over the last several decades, further study has revealed multiple disadvantages. Portal hypertension, portal vein thrombosis, [...]

Received: 08 October 2018;  Published: 28 December 2018;  doi: 10.21926/obm.transplant.1804036

Abstract

Islet transplantation has proven to be a viable treatment for individuals suffering from both Type 1 Diabetes Mellitus (T1D) and chronic pancreatitis. However, a variety of challenges limit the effectiveness of this procedure by reducing the number of islets that survive the harvesting and transplan [...]
