Tissue Renewal without Stem Cells01:23

Tissue Renewal without Stem Cells

2.2K
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Insulin: Biosynthesis, Chemistry, and Preparation01:25

Insulin: Biosynthesis, Chemistry, and Preparation

1.9K
The endoplasmic reticulum (ER) of pancreatic β-cells synthesizes preproinsulin, which consists of a signal peptide, A and B chains, and a C-peptide. Preproinsulin is then cleaved and folded into proinsulin, which translocates to the Golgi apparatus for sorting and packaging into secretory granules. In these granules, enzymatic clipping generates insulin and C-peptide.
Damage or functional impairment of β-cells inhibits insulin production, leading to diabetes. Diabetes treatment...

Area of Science:

  • Endocrinology
  • Transplantation Immunology
  • Metabolic Diseases

Background:

  • Insulin-dependent diabetes mellitus (IDDM) poses significant management challenges, particularly for those experiencing life-threatening hypoglycemia.
  • Current medical management often falls short for select patients, necessitating advanced therapeutic strategies.

Purpose of the Study:

  • To summarize current outcomes of beta-cell replacement strategies.
  • To provide an algorithm for selecting appropriate beta-cell replacement modalities.
  • To highlight advantages, disadvantages, and ongoing research in beta-cell replacement therapy.

Main Methods:

  • Review of recent literature on islet cell allotransplantation and pancreas transplantation.
  • Analysis of outcomes, complications, and patient quality of life.
  • Identification of active areas of investigation in beta-cell replacement.

Main Results:

  • Recent islet cell allotransplantation outcomes show improvement, comparable to pancreas-alone transplantation.
  • Active research focuses on islet isolation techniques, graft monitoring, and managing immune responses.
  • Islet transplantation effectively eliminates hypoglycemia, normalizes HbA1c, and reduces microvascular complications.

Conclusions:

  • Beta-cell replacement is a viable option for IDDM patients with severe hypoglycemia unresponsive to medical therapy.
  • Transplantation offers a physiologic euglycemic state superior to emerging non-transplant technologies.
  • Islet transplantation improves quality of life and demonstrates favorable mid- to long-term outcomes with a manageable complication profile.
