Decoding How Stem Cells Transform into Olfactory Neurons in Living Animals

Swift Summary

• Researchers from the University of Alabama at Birmingham adn the University of Illinois Chicago investigated how olfactory stem cells transform into neurons responsible for the sense of smell.
• Using zebrafish embryos as a model, they employed techniques like high-resolution imaging, cell fate tracking, and single-cell RNA sequencing to uncover mechanisms driving this transformation.
• They identified a bistable toggle switch system that assigns cell fates and organizes progenitor cells into cellular “neighborhoods,” facilitating neurogenesis at multiple levels-cellular clusters and organs.
• The study highlights how fluctuating signals are streamlined to ensure continuous growth amid complex microenvironments in living animals.
• Lead researchers Sriivatsan Govinda Rajan, Ph.D., and Ankur Saxena, Ph.D., hope these findings could pave the way for new treatments targeting neurodevelopmental or neurodegenerative disorders in humans.
• Human nasal neurons regenerate approximately every couple of months throughout life-a phenomenon inspiring inquiries into broader applications across vertebrates.
