Abstract
Recent advances in stem cell technology have allowed researchers to generate 3D cerebral organoids (COs) from human pluripotent stem cells (hPSCs). Indeed, COs have provided an unprecedented opportunity to model the developing human brain in a 3D context, and in turn, are suitable for addressing complex neurological questions by leveraging advancements in genetic engineering, high resolution microscopy, and tissue transcriptomics. However, the use of this model is limited by substantial variations in the overall morphology and cellular composition of organoids derived from the same pluripotent cell line. To address these limitations, we established a robust, high-efficiency protocol for the production of consistent COs by optimizing the initial phase of embryoid body (EB) formation and neural induction. Using this protocol, COs can be reproducibly generated with a uniform size, shape, and cellular composition across multiple batches. Furthermore, organoids that developed over extended periods of time (3–6 months) showed the establishment of relatively mature features, including electrophysiologically active neurons, and the emergence of oligodendrocyte progenitors. Thus, this platform provides a robust experimental model that can be used to study human brain development and associated disorders.

Background
Recent advancements in the in vitro development of 3D cerebral organoids (COs) derived from human pluripotent stem cells (hPSCs) have provided an unprecedented opportunity to model the developing human brain and relevant complex diseases in an experimentally tractable system. Indeed, this approach has allowed researchers to study early brain development and the consequences of alterations associated with various human neurological disorders, such as Alzheimer’s, blindness, Autism Spectrum Disorder (ASD), and Zika virus infection (Lancaster and Knoblich, 2014b; Quadrato et al., 2016; Di and Kriegstein, 2017; Huch et al., 2017; Amin and Paşca, 2018; Rossi et al., 2018; Chen et al., 2019). In addition, several groups have applied COs to study and establish preclinical models of human brain cancers such as glioblastoma multiforme (Drost and Clevers, 2018; Linkous et al., 2018). In recent years, numerous protocols have emerged to facilitate the development of region specific-COs by controlling the underlying cell signaling pathways with exogenous growth factors and small molecule inhibitors to guide cell fate changes as the organoid matures (Lancaster et al., 2013; Mariani et al., 2015; Jo et al., 2016; Qian et al., 2016; Birey et al., 2017; Quadrato et al., 2017; Watanabe et al., 2017; Pollen et al., 2019; Velasco et al., 2019; Yoon et al., 2019). However, due to the fact that human whole-brain organoids are largely produced by intrinsic self-patterning and do not rely on controllable exogenous factors, stochastic differentiation often leads to cellular diversity, which is amplified with extended culture. Unfortunately, the considerable variability between individual organoids obtained using whole-brain differentiation platforms can therefore limit the utility of these COs for studying disease mechanisms or the development of potential therapeutics. Here, we describe our robust protocol for efficiently and reproducibly generating mature, uniform human COs (Figure 1). By optimizing an established protocol for the creation of self-patterned whole-brain organoids (Lancaster and Knoblich, 2014a; Lancaster et al., 2013), we successfully generated phenotypically uniform forebrain organoids with reproducible cell-type compositions.
