Insights

Scientists are developing human pluripotent stem cells to create insulin-producing beta cells. Further research is needed to achieve the glucose responsiveness seen in mature beta cells.

Area of Science:

  • Stem cell biology
  • Endocrinology
  • Developmental biology

Background:

  • Human pluripotent stem cells (hPSCs) hold promise for regenerative medicine.
  • Differentiation protocols aim to mimic developmental pathways for generating specific cell types.

Purpose of the Study:

  • To advance the generation of functional human pancreatic endocrine cells from hPSCs.
  • To identify key pathways for achieving mature beta cell glucose responsiveness.

Main Methods:

  • Utilizing developmental biology principles to guide hPSC differentiation.
  • Employing stem cell differentiation protocols.

Main Results:

  • Progress has been made in generating pancreatic endocrine cells, including insulin-producing beta cells, from hPSCs.
  • Achieving robust glucose responsiveness, a critical postnatal beta cell function, remains a challenge.

Conclusions:

  • hPSC differentiation protocols are nearing the generation of fully fledged pancreatic endocrine cells.
  • Further investigation into specific developmental or postnatal pathways is required to confer mature glucose responsiveness to hPSC-derived beta cells.

Production of Pharmaceuticals

Industrial insulin production uses genetically engineered E. coli expressing a proinsulin gene controlled by a tryptophan promoter and containing a methionine linker for later cleavage. The cells also carry ampicillin resistance for selective growth. Seed cultures are stored at −80 °C and production begins by thawing a small amount to inoculate starter cultures, which are progressively scaled to a 50,000-L bioreactor. In the bioreactor, E. coli grow in nutrient-rich media under...

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...

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...

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 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...
