Research on single-cell spatiotemporal transcriptomic and chromatin accessibility profiling has been conducted, with some studies focusing on the developing postnatal human and macaque prefrontal cortex, while others appear to explore different areas, such as the maternal-fetal interface or brain development in other species. The findings may shed light on various topics, including brain maturation and disease-related genes. However, the specific outcomes and applications of the research are unclear, with different outlets reporting on different aspects of the study.
