Topological Insights into Embryogenesis: Linking Germ Layer Derivations to Shared Pathologies

During early embryogenesis, the trilaminar germ layers—ectoderm, mesoderm, and endoderm—undergo complex topological transformations and molecular interactions that define tissue differentiation. The ectoderm, which gives rise to the central nervous system and epidermis, exhibits developmental pathways closely tied to morphogenetic gradients and folding dynamics. This study explores how shared topological features and signalling pathways across germ layers can generate resembling pathologies under comparable disruptions, such as neurocutaneous syndromes and craniofacial anomalies. By integrating concepts from developmental biology and topological data analysis, this work provides a theoretical framework to understand the intersection of embryonic topology and disease etiology, offering insights into novel diagnostic and therapeutic approaches.
