Chromatin Modification in iPS Cells01:32

Chromatin Modification in iPS Cells

2.3K
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...

Induced Pluripotent Stem Cells

28.7K
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...

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).

Somatic to iPS Cell Reprogramming

2.9K
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...

Area of Science:

  • Stem Cell Biology
  • Genomics
  • Molecular Biology

Background:

  • Human Embryonic Stem Cells (hESCs) are crucial for studying pluripotency and early development.
  • Accurate identification of the hESC transcriptome is essential for understanding these processes.
  • Existing gene annotation methods have limitations in comprehensively characterizing the hESC transcriptome.

Purpose of the Study:

  • To develop and validate a novel tool for integrating hybrid sequencing data to characterize the hESC transcriptome.
  • To establish a more reliable and comprehensive transcriptome profile for hESCs.
  • To identify novel transcripts within the hESC population.

Main Methods:

  • Development of the IDP (Integrative Data Platform) tool.
  • Integration of hybrid sequencing data (e.g., cDNA, EST, RNA-Seq).
  • Bioinformatic analysis for transcript identification and annotation.

Main Results:

  • The IDP tool successfully integrated diverse sequencing data.
  • A more comprehensive and reliable hESC transcriptome was characterized.
  • Numerous novel transcripts were discovered within the hESC transcriptome.

Conclusions:

  • The IDP tool enhances the accuracy and completeness of hESC transcriptome analysis.
  • This improved transcriptome characterization facilitates deeper insights into hESC pluripotency and differentiation.
