Researchers in the Schübeler lab, pictured above, have made important discoveries. In the process, they are revealing how muscle cells form and neurons form through cellular decision making. This pivotal study, published in a recent research paper, reveals the intricate roles of two closely related transcription factors: NGN2 and MyoD1. Together, each of these clues guides the same type of blank slate cells along different paths—one way to become neurons, another to become muscle cells.
The study emphasizes that every cell in the body contains the same DNA but utilizes different segments of this genetic material to define its specific role. Naturally, transcription factors are key players in this differentiation. Subtle changes of the DNA even at the level of bases themselves are incredibly important. Even a small alteration, sometimes as minor as a single letter, can significantly impact gene activation and thus influence cellular destiny.
While NGN2 is essential for driving cells down a path to become neurons, MyoD1 directs them to become muscle cells instead. Vondriska’s research shows that the binding patterns of these transcription factors to DNA are predictive of cell fate. This conclusion provides new details about the process that occurs within cells as they become specialized.
This means that undifferentiated cells can be coaxed to develop either into neurons, or muscle cells. Their transformation largely turns on which transcription factors are at play. By figuring out which proteins go in with these transcription factors, researchers were able to control the activation of certain genes. This finding adds complexity to our understanding of how cellular identity is established.
