Understanding the origins of Malformations of the Cortical development
Ossola and Kalebic. Frontiers in Neuroscience 2022
The cerebral cortex – the outer brain layer – accounts approximately for half of the human and mammalian brain mass and controls language, memory, reasoning, and consciousness. Specialised cortex cells – the neural progenitors – are responsible for the specification, positioning and maturation of neurons in the cortex, which are essential for brain development. Alteration of any of these events leads to structural abnormalities of the cerebral cortex, called Malformations of Cortical Development (MCDs). By impairing brain development, MCDs result in abnormal brain size and thickness, which represent the basis of several neurodevelopmental disorders.
Nereo Kalebic and Chiara Ossola at the HT Neurogenomics Research Centre review how two key features of the neuronal progenitor cells, i.e. their ability to proliferate and polarise, impact on brain development, if misregulated. Furthermore, they discuss the role of cell signaling pathways and metabolism in the onset of MCDs and how using appropriate in vivo and in vitro models can help advancing personalized medicine. In summary, the authors provide a comprehensive overview of how the cell biology of the neuronal progenitors is involved in MDC onset.
The review is published in Frontiers in Neuroscience.

Human stem cells recapitulate early embryonic development in vitro
Differentiation of pluripotent stem cells (PSCs) has successfully been used to study tissue and organ development in vitro. Eleonora Conti and Oliver Harschnitz review the pros and cons of using human PSCs to investigate the development of placodes – embryonic structures giving rise to diverse organs – during the early steps of human embryonic development […]
Derailing molecular cargo trains in cilia makes them turn around
Researchers at the Human Technopole and Max Planck Institute of Molecular Cell Biology and Genetics show how molecular cargo trains change direction in cellular micro-antennas. Cilia are antenna-like structures that protrude outwards from the surface of eukaryotic cells. Misassembled cilia in humans can cause numerous diseases from infertility to lung malfunction. The assembly and maintenance […]
