Human brain organoids offer a powerful tool to study neurodevelopment, yet faithfully recapitulating the intricate spatial organization and cell type diversity of the fetal telencephalon remains a challenge. This study focuses on subpallial organoids, models derived to mimic the ganglionic eminences, the source of GABAergic interneurons and medium spiny neurons. We investigate the role of key morphogens such as SHH, FGF, WNT, and BMP in patterning these organoids and directing cell fate specification. By manipulating morphogen signaling pathways, we aim to generate organoids enriched in specific neuronal subtypes, including somatostatin, parvalbumin, and calretinin-positive interneurons, as well as medium spiny neurons. Single-cell RNA sequencing analysis is employed to characterize the transcriptomic profiles of these organoids and compare them to fetal brain data, assessing their developmental fidelity. Furthermore, we explore the integration of bioengineering techniques, such as PDMS devices and controlled morphogen gradients, to enhance spatial patterning and improve the organoids' ability to recapitulate the complex developmental processes of the human subpallium. This work contributes to the ongoing effort to refine organoid models, providing a more accurate platform for studying early neural development and its associated disorders.
