A major barrier in understanding nervous system development is modeling the cellular interactions that form the human brain. Recently, in the journal Nature, Lancaster et al. (2013) established a protocol for culturing pluripotent stem cell (PSC)-derived "cerebral organoids" that mimics the developing human brain's cellular organization, segregates into distinct brain regions, and models microcephaly.
理解神经系统发育的主要障碍是模拟形成人类大脑的细胞相互作用。最近,在《自然》杂志上,兰开斯特等人(2013)建立了一种培养多能干细胞(PSC)衍生的“类脑器官”的方案,该方案模拟了发育中人类大脑的细胞组织,可分离成不同的脑区,并可模拟小头畸形。
