Tissue Renewal without Stem Cells01:23

Tissue Renewal without Stem Cells

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...
Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are co-secreted in...
Insulin Secretory Vesicles01:05

Insulin Secretory Vesicles

Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
Insulin: Biosynthesis, Chemistry, and Preparation01:25

Insulin: Biosynthesis, Chemistry, and Preparation

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 primarily uses...
Type I Diabetes I: Introduction01:12

Type I Diabetes I: Introduction

Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...

Summary

Endogenous pancreatic beta-cell replenishment, specifically neogenesis from progenitor cells, offers a potential therapeutic strategy for type 1 diabetes. Further research is needed to overcome challenges in beta-cell regeneration and function.

Area of Science:

  • Endocrinology
  • Regenerative Medicine
  • Diabetes Research

Background:

  • Type 1 diabetes is characterized by the loss of pancreatic beta-cells.
  • Beta-cell replacement is a potential therapy, but faces challenges like autoimmunity and cell availability.
  • Endogenous replenishment offers a promising avenue if autoimmunity can be managed.

Purpose of the Study:

  • To examine the potential of endogenous pancreatic beta-cell replenishment as a therapeutic tool.
  • To discuss the roles of beta-cell replication and neogenesis in diabetes.
  • To analyze findings from rodent models and human studies regarding neogenesis.

Main Methods:

  • Review of existing literature on beta-cell replication and neogenesis.
  • Analysis of data from rodent models of pancreatic growth and regeneration.
  • Examination of human studies on beta-cell neogenesis.

Main Results:

  • Two pathways for endogenous beta-cell replenishment exist: replication and neogenesis.
  • Replication of existing beta-cells is insufficient in type 1 diabetes due to cell loss.
  • Neogenesis, the formation of new islet cells from progenitor cells, is a key focus for therapeutic potential.

Conclusions:

  • Inducing neogenesis could provide a crucial starting population for beta-cell expansion.
  • The occurrence of neogenesis post-birth is debated but supported by extensive observations.
  • Understanding neogenesis in humans is critical for developing effective diabetes therapies.
