Summary
Human microvascular endothelial cells (HMECs) co-cultured with human pluripotent stem cells (hPSCs) promote the development of functional pancreatic beta cells. This interaction activates signaling pathways crucial for generating insulin-producing cells.
Area of Science:
- Stem cell biology
- Endocrinology
- Developmental biology
Background:
- Endothelial cells (ECs) are critical for pancreatic development.
- Human pluripotent stem cells (hPSCs) offer a potential source for pancreatic beta cells.
- Generating functional beta cells in vitro remains a significant challenge.
Purpose of the Study:
- To investigate the role of endothelial cells in pancreatic beta cell differentiation from hPSCs.
- To determine if co-culture with human microvascular endothelial cells (HMECs) enhances the generation of functional pancreatic beta cells.
Main Methods:
- Human pluripotent stem cells (hPSCs) were differentiated into embryoid bodies (EBs).
- EBs were co-cultured with HMECs in collagen gels or cultured alone (controls).
- Pancreatic beta cell markers, insulin secretion (in vitro and in vivo), and signaling pathway activation (BMP-2, 4) were assessed.
Main Results:
- Co-cultured EBs showed increased expression of mature beta cell markers and enhanced insulin secretion compared to controls.
- Transplanted EBs in immunodeficient mice exhibited higher human C-peptide secretion and reduced hyperglycemia.
- Upregulation of bone morphogenetic proteins (BMP-2, 4) was observed in co-cultured cells.
Conclusions:
- Endothelial cells provide essential signaling cues for the derivation of functional insulin-producing beta cells from hPSCs.
- Activation of the BMP pathway by ECs is crucial for this differentiation process.
- This study highlights a promising strategy for generating beta cells for potential therapeutic applications.

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.

01:23Tissue 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.

Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

2.9K
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.

01:21EPS and iPS Cells in Disease Research
3.5K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
