Research has been conducted on the development of brain regions in various species, including cynomolgus monkeys, Bama miniature pigs, and mice, using techniques such as transcriptomic and proteomic analyses. These studies aim to understand the spatiotemporal changes that occur during brain development, from fetal to neonatal stages. The research also explores the application of these techniques to other areas, including the study of human diseases like Alzheimer's and the development of other tissues, such as adipose tissue.
