Insights

G protein-coupled receptor (GPCR) pathways are crucial for regulating stem cell growth and differentiation. Understanding GPCR signaling offers new therapeutic avenues for stem cell treatments.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Pharmacology

Background:

  • Stem cell therapeutics hold promise for treating diseases, but regulatory mechanisms remain unclear.
  • G protein-coupled receptor (GPCR) pathways are increasingly recognized for their role in stem cell regulation.
  • This review bridges stem cell biology and GPCR signaling research.

Purpose of the Study:

  • To explore the interplay between stem cell biology and GPCR signaling.
  • To elucidate how GPCRs regulate stem cell pluripotency and differentiation.
  • To discuss the therapeutic potential of targeting GPCRs in stem cell applications.

Main Methods:

  • Review of existing literature on stem cell biology and GPCR signaling.
  • Analysis of conserved pathways governing pluripotency and differentiation.
  • Summarization of specific GPCR examples impacting stem cell function.

Main Results:

  • Conserved pathways significantly regulate stem cell pluripotency and differentiation in both mouse and human cells.
  • GPCR signaling pathways can impact these fundamental stem cell processes.
  • Specific GPCRs across major subfamilies have demonstrated roles in stem cell regulation.

Conclusions:

  • GPCRs are key regulators of stem cell function.
  • Targeting GPCRs presents promising therapeutic strategies for stem cell-based treatments.
  • Further research into GPCR-stem cell interactions can advance regenerative medicine.

Maintenance of the ES Cell State01:14

Maintenance of the ES Cell State

The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...
Somatic to iPS Cell Reprogramming01:29

Somatic to iPS Cell Reprogramming

Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012 for this...
Combinatorial Gene Control02:33

Combinatorial Gene Control

Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Induced Pluripotent Stem Cells

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 called induced pluripotent stem...

Induced Pluripotent Stem Cells

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).
