Cell Fate Reprogramming of Nematode Germ Cells into Neurons

448
This video demonstrates cell fate reprogramming of nematode germ cells into neurons. Transgenic larvae of the nematode Caenorhabditis elegans are subjected to RNA interference (RNAi) to knock down a specific chromatin-regulating factor, making the germ cells of their progeny more susceptible to cell fate reprogramming. Heat shock is applied to the progeny, inducing the germ cells to express a neuron-specific transcription factor that triggers their transformation into neurons, which is...

Fate Mapping06:58

Fate Mapping

61.9K
Fate mapping is a technique used to understand how embryonic cells divide, differentiate, and migrate during development. In classic fate mapping experiments, cells in different areas of an embryo are labeled with a chemical dye and then tracked to determine which tissues or structures they form. Technological improvements now allow for individual cells to be marked and traced throughout embryonic development and adulthood.
This video reviews the concepts behind fate mapping, and then details a...

Blastomere Explants to Test for Cell Fate Commitment During Embryonic Development

15.8K
The fate of an individual embryonic cell can be influenced by inherited molecules and/or by signals from neighboring cells. Utilizing fate maps of the cleavage stage Xenopus embryo, single blastomeres can be identified for culture in isolation to assess the contributions of inherited molecules versus cell-cell...

Area of Science:

  • Cell Biology
  • Developmental Biology
  • Stem Cell Research

Background:

  • Cellular reprogramming allows somatic cells to become induced pluripotent stem cells (iPSCs).
  • The precise molecular mechanisms and key mediators governing this reprogramming process are not fully understood.

Purpose of the Study:

  • To identify novel genes and understand the mechanisms involved in somatic cell reprogramming into iPSCs.
  • To investigate the role of candidate genes in modulating cell fate transitions.

Main Methods:

  • Utilized siRNA-mediated knockdown of candidate genes during somatic cell reprogramming.
  • Employed assays to measure the efficiency of induced pluripotent stem cell reprogramming.
  • Analyzed the expression of reprogramming factors and the dynamics of enhancer activity.

Main Results:

  • Identified Tox4 as a novel factor essential for efficient iPSC reprogramming.
  • Demonstrated that Tox4 is required early in reprogramming to generate intermediates, regardless of conditions.
  • Showed Tox4's role in regulating reprogramming factor expression and enhancer accessibility.
  • Confirmed Tox4's necessity for fibroblast-to-neuron conversion, indicating a broader cell fate modulation role.

Conclusions:

  • Tox4 is a novel transcriptional modulator that mediates cell fate reprogramming.
  • Tox4 plays a critical role in the transition from somatic to pluripotent and neuronal cell states.
