2023
Development is the complex process through which a single-celled embryo transforms into a multicellular organism. Developmental processes are guided by information encoded in an organism's DNA, and geneticists are trying to understand how this information leads to a fully formed organism. This video reviews seminal research in the field of developmental biology, including the identification of specific genes that control various embryonic processes. An introduction to the major questions asked...

An Introduction to Developmental Neurobiology

2023
Developmental neuroscience is a field that explores how the nervous system is formed, from early embryonic stages through adulthood. Although it is known that neural progenitor cells follow predictable stages of proliferation, differentiation, migration, and maturation, the mechanisms controlling the progression through each stage are incompletely understood. Studying development is not only important for understanding how complex structures are assembled, but also for characterizing and...

Molecular signals play a major role in the complex processes occurring during embryonic development. These signals regulate activities such as cell differentiation and migration, which contribute to the formation of specific cell types and structures. The use of molecular approaches allows researchers to investigate these physical and chemical mechanisms in detail. This video will review a brief history of the study of molecular events during development. Next, key questions asked by molecular...

Explant Culture for Developmental Studies
0 Views •
2023
Explant culture is a technique in which living cells or tissues are removed from an embryo for continued development outside of the organism. This ex vivo approach allows researchers to manipulate and observe developing tissues in ways that are not possible in vivo. Once established, explant culture is frequently used to understand the role of genes and signaling molecules in organogenesis. This video will first introduce the basic principles of explant culture and demonstrate a protocol to...

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Progression depends on communication between signaling molecules, receptors, and transcription factors. Signals received at the cell surface can influence gene expression, while transcription factors help regulate which developmental programs a cell follows. These interactions affect cell division, migration, differentiation, and tissue patterning, allowing molecular events to produce coordinated changes across cells and developing tissues.
Morphogens, receptors, and transcription factors contribute at different points in the signaling process. Morphogens provide developmental signals, receptors enable cells to detect those signals, and transcription factors regulate gene expression inside the cell. Together, these components connect extracellular communication with cellular decisions, influencing whether cells divide, migrate, differentiate, or contribute to particular tissue patterns.
A disruption can alter the regulated sequence of gene expression and signaling interactions required for normal formation. If cells receive, interpret, or execute developmental instructions incorrectly, processes such as migration, differentiation, or tissue patterning may be affected. Studying these points of disruption helps researchers connect altered developmental programs with congenital disorders and identify where normal formation has changed.
Researchers combine genetic, imaging, and molecular approaches to map the events and interactions that shape development. Genetic methods help examine pathway-related changes, imaging follows cells or tissues as they change, and molecular approaches analyze regulated components and gene expression. Using these approaches together can reveal pathway organization, identify disruption points, and relate molecular events to cellular outcomes.
Mapping can show how molecular signals and regulated gene expression relate to cell division, migration, differentiation, and tissue patterning over time. It can also identify stages or components at which development is altered. This information supports explanations of embryonic formation and organ development while providing a framework for investigating congenital disorders and altered developmental programs.
Their study extends to regeneration, stem cell biology, regenerative medicine, and disease research. Developmental programs can provide a framework for examining how tissues form, change, or recover, while pathway disruptions can help researchers investigate disease-related alterations. These applications connect fundamental biology with efforts to understand organ development, tissue renewal, and conditions associated with abnormal development.
