This learning path provides a systematic exploration of regeneration mechanisms across species, from foundational developmental biology to advanced molecular regulation. It covers key concepts such as stem cells, epimorphosis, morphallaxis, and the use of model organisms like planarians and axolotls, culminating in an understanding of regenerative limitations in mammals.
This learning path explores the genetic and developmental mechanisms underlying sex determination, from basic genetics to the molecular and hormonal regulation of gonad development. It covers primary sex determination, the role of SRY, and the downstream pathways leading to testis or ovary formation, as well as the influence of sex hormones on sexual differentiation.
This learning path guides pre-med and biology students through the systematic development of the cardiovascular system, from basic embryology to heart tube formation, looping, septation, coronary vessel development, and congenital defects. It emphasizes the underlying mechanisms and clinical relevance, preparing learners for advanced studies in developmental biology and medicine.
This learning path guides developmental biology students through the fundamental principles and molecular mechanisms underlying vertebrate limb development. It covers the establishment of the limb bud, the roles of key signaling centers (AER, ZPA), and the genetic control of patterning and digit formation, culminating in an integrated understanding of limb morphogenesis.
A systematic path covering the fundamental processes of early neural development, from gastrulation and neural induction through neurulation, neural crest formation, and early brain regionalization. It also addresses neural tube defects as a clinical correlate. Designed for university-level neuroscience and developmental biology students.
This learning path guides developmental biology students through the fundamental principles of organ development, starting with basic embryology and progressing through key concepts such as organ rudiments, epithelial-mesenchymal interactions, and branching morphogenesis, with detailed examples from heart and kidney development.
This learning path guides developmental biology students through the molecular and cellular mechanisms that establish the anteroposterior, dorsoventral, and left-right axes in vertebrate embryos. Beginning with foundational concepts, it explores the roles of the Spemann organizer, BMP, Nodal, Wnt, and Hox genes, culminating in an integrated understanding of axis specification.
This learning path systematically explores how the anterior-posterior and dorsal-ventral axes of the fruit fly embryo are established through the sequential action of maternal effect, gap, pair-rule, and segment polarity genes. It begins with essential background in Drosophila development and basic genetics, then builds a conceptual framework of the gene regulatory hierarchies that pattern the embryo.
This learning path guides cell biology students through the molecular and cellular processes underlying cell specialization. It begins with fundamental cell biology concepts, then explores stem cell properties, pluripotency, lineage commitment, and differentiation pathways, culminating in an understanding of how cells acquire and maintain their fates.
This learning path provides a systematic introduction to morphogenesis, the developmental biology discipline that studies how cellular behaviors shape the embryo. It covers the core cellular mechanisms—cell adhesion, cell shape changes, cell migration, and cell death—and integrates them into tissue-level processes such as folding and convergent extension. The path is designed for undergraduate biology students with a basic background in developmental biology.
