What are primary cilia?
Primary cilia are small, hair-like structures on the surface of cells that play important roles in signaling and development.
Why are hIPSC models used in this study?
hIPSC models provide a relevant platform to study human-specific developmental processes and diseases.
What is the significance of neocortical development?
Neocortical development is crucial for cognitive functions and understanding its mechanisms can inform treatments for neurological disorders.
How do 2D and 3D models differ?
2D models are flat cultures of cells, while 3D models mimic the natural architecture of tissues, providing more relevant biological contexts.
What methodologies are used to analyze primary cilia?
Qualitative and quantitative analyses are employed to assess the biogenesis and function of primary cilia in the models.
