Insights

All three pannexin (Panx) genes are expressed in human pluripotent stem cells. Differentiation did not affect Panx1 expression, but slightly increased Panx2 and Panx3 expression in some cell types.

Area of Science:

  • Cell Biology
  • Stem Cell Research
  • Molecular Biology

Background:

  • Pannexins (Panx) are channel proteins crucial for cellular communication and development.
  • Their role in human pluripotent stem cells (hPSCs) remains incompletely understood.

Purpose of the Study:

  • To investigate the expression of Panx1, Panx2, and Panx3 mRNAs in undifferentiated and differentiated hPSCs.
  • To analyze the impact of differentiation on pannexin gene expression.

Main Methods:

  • Analysis of Panx1-3 mRNA expression in undifferentiated hPSCs (hCBiPS2, HSC_F1285_T-iPS2, HES-3).
  • Induction of undirected differentiation into embryoid bodies.
  • Quantification of pannexin gene expression post-differentiation.

Main Results:

  • Panx1, Panx2, and Panx3 mRNAs were detected in all undifferentiated hPSC lines, with Panx1 showing the highest expression.
  • Undirected differentiation yielded cells from all three germ layers.
  • Panx1 expression remained stable post-differentiation; Panx2 expression slightly increased in all differentiated cell types; Panx3 expression showed a slight increase in differentiated hCBiPS2 cells.

Conclusions:

  • Human pluripotent stem cells express all three pannexin genes.
  • Pannexin expression patterns are modulated during stem cell differentiation.
  • Pannexins may play a role in early human development and stem cell biology.

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

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...

Adult Stem Cells01:33

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Embryonic Stem Cells

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...
