Cell and Developmental Biology explores the fundamental principles governing the structure and function of cells, as well as the mechanisms driving the development of multicellular organisms. This course covers key topics such as cell structure, membrane dynamics, intracellular signaling, the cell cycle, and apoptosis. It also delves into how cells differentiate, communicate, and organize during the development of tissues and organs, examining processes like pattern formation, morphogenesis, and stem cell biology. Integrating molecular, genetic, and biochemical perspectives, this course provides a comprehensive understanding of how cellular behaviors shape development from single-cell embryos to complex organisms.
