RESEARCH FIELD

Developmental Biology

Developmental biology investigates how a single fertilized egg gives rise to the extraordinary complexity of a multicellular organism through coordinated cell division, differentiation, and morphogenesis. Single-cell RNA sequencing now allows researchers to chart the complete transcriptional trajectories of every cell lineage from zygote to adult. Spatial transcriptomics maps gene expression within intact tissue sections, linking molecular identity to anatomical position. Organoid systems reconstitute aspects of organ development in vitro, enabling mechanistic studies of human tissue formation previously inaccessible to experimentation. These advances are transforming regenerative medicine, birth-defect research, and our understanding of evolutionary changes in body plans.
