Summary
Protein kinase C (PKC) acts as a master switch in human pluripotent stem cell differentiation. PKC regulates the balance between embryonic and extraembryonic cell fates, crucial for development and stem cell applications.
Area of Science:
- Developmental Biology
- Stem Cell Biology
- Cell Signaling
Background:
- Mitogenic signaling pathways and master regulators are critical for cell fate determination during embryogenesis.
- Understanding these pathways is key for advancing stem cell applications.
Purpose of the Study:
- To identify intrinsic master regulators controlling cell fate decisions in human pluripotent stem cells (hPSCs).
- To elucidate the role of protein kinase C (PKC) in directing embryonic versus extraembryonic lineage specification.
Main Methods:
- Investigated the role of PKC in hPSC differentiation.
- Manipulated PKC activity to observe effects on lineage specification downstream of BMP4 signaling.
- Analyzed the interplay between PKC, BMP4, and β-catenin (CTNNB1) signaling.
Main Results:
- PKC acts as a master switch between embryonic and extraembryonic fates in hPSCs.
- PKC activation promotes extraembryonic lineage induction, overriding mesoderm differentiation.
- Specific PKC isoforms (PKCα and PKCδ) play distinct roles in mesoderm suppression and trophoblast fate, respectively.
- PKC inhibition leads to β-catenin activation and a switch towards mesoderm lineages.
Conclusions:
- PKC is an intrinsic signaling boundary that segregates embryonic and extraembryonic lineages.
- Modulating PKC activity can enhance directed cell differentiation in stem cell applications.

01:29Somatic to iPS Cell Reprogramming
2.3K
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...

01:24Methods of Nuclear Reprogramming
1.9K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

01:32Chromatin Modification in iPS Cells
1.7K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

01:06Induced Pluripotent Stem Cells
4.3K
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).

01:14Maintenance of the ES Cell State
2.2K
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...
