Area of Science:

  • Biomedical Engineering
  • Endocrinology
  • Drug Discovery

Background:

  • Diabetes prevalence is increasing globally, with beta-cell dysfunction central to both type 1 and type 2 forms.
  • Current diabetes drug evaluation relies on cell lines or rodent islets, which lack human islet similarity, limiting predictive value.
  • Existing methods assess static insulin secretion, failing to capture dynamic physiological responses.

Purpose of the Study:

  • To develop an advanced platform for more accurate diabetes drug discovery.
  • To overcome limitations of current in vitro models for assessing drug efficacy.
  • To create a system that better mimics human pancreatic islet physiology.

Main Methods:

  • Development of an Engineered Micro-Pancreas platform.
  • Utilizing a decellularized porcine lung-derived micro-scaffold.
  • Seeding cadaveric human islets onto the micro-scaffold.

Main Results:

  • The Engineered Micro-Pancreas demonstrated viability in vitro for up to three months.
  • Sustained insulin secretion was observed, comparable to freshly isolated human islets.
  • The platform supports real-time, physiology-mimicking drug screening.

Conclusions:

  • The Engineered Micro-Pancreas offers a superior in vitro model for diabetes drug discovery.
  • This platform enhances the predictive value of preclinical drug screening.
  • It holds significant potential for advancing the development of new diabetes treatments.
