Sergiu P. Pașca

Pașca was born in Cluj-Napoca in the western part of Romania also known as Transylvania. He was raised in nearby Aiud during the last years of communism.[8] Pașca showed early on an interest in chemistry. He set up his first science lab at the age of 11, in the basement of his parents’ house.[9] In the final year of high school, he won a prize in the national chemistry Olympiad, earning a scholarship to attend the university of his choice in Romania. In 2001, Pașca enrolled in the Iuliu Hațieganu University of Medicine and Pharmacy at Cluj-Napoca.[1] As a medical student, he worked with Professor Maria Dronca to explore biochemical defects in autism spectrum disorders. At the same time, he studied electrophysiology at the Max Planck Institute for Brain Research in Frankfurt in Germany under Dr Danko Nikolic. After obtaining his M.D. in 2007, Pașca went to Stanford University in early 2009 as a postdoctoral fellow with Professor Ricardo Dolmetsch. At Stanford, he developed methods to derive neurons from induced pluripotent stem cells (iPSC) and used these neural cultures to identify cellular phenotypes associated with brain disorders, including Timothy syndrome and Dravet syndrome.[10][11][12][13]

Pașca’s laboratory at Stanford University explores the biological mechanisms of brain disorders using cellular models of the human brain.[14] Pașca developed some of the early in-a-dish models of disease by deriving neurons from skin cells taken from patients with genetic forms of autism and other neurodevelopmental disorders.[15][16] These patient neurons helped uncover the cellular defects of genetic mutations and demonstrated the promise of this novel technology. In his laboratory, Pașca went further to develop a novel platform that allows to take iPSC from any individuals and engineer lab-grown self-assembling three-dimensional (3D) structures called brain region-specific spheroids or organoids.[17] This method was listed among the Key Advances in hiPSC Disease Modeling of the Last Decade by the journal Cell Stem Cell,[18] and Organoids were named Methods of the Year in 2017 by Nature Methods.[19] These 3D brain tissue resemble specific regions of the nervous system[20][21] and his laboratory has maintained these cultures for over 800 days in vitro to show maturation of cells, including astrocytes, into postnatal stages. His work on astrocytes was inspired by the late Stanford neurobiologist Ben Barres. Pașca has also demonstrated that brain-region specific organoids can be fused to form brain assembloids and employed this preparation to study the cross-talk between cells in the developing human brain and to mimic human brain circuits in a dish.[22] This work was listed among the Top Research Advances of 2017 by the National Institutes of Health.[23] In 2022, his group demonstrated the successful integration of human cortical organoids into the developing rat cerebral cortex. Human neurons displayed advanced maturation in vivo, responded to whisker stimulation and were capable of influencing the behavior of the rat in a reward task.[24]

Pașca is the co-director of the CSHL Workshop on autism spectrum disorders.[25]
