Murine In Utero Electroporation
0 Views •
2023
In utero electroporation is an important technique for studying the molecular mechanisms that guide the proliferation, differentiation, migration, and maturation of cells during neural development. Electroporation enables the rapid and targeted delivery of material into cells by utilizing electrical pulses to create transient pores in cell membranes. Although electroporation has traditionally been used in in vitro studies, scientific advancements have now broadened its utilization to intact...

2017
This manuscript provides protocols that use in utero electroporation (IUE) to describe the structural connectivity of neurons at the single-cell level and the excitability of fluorescently labeled neurons. Histology is used to characterize dendritic and axonal projections. Whole-cell recording in acute slices is used to investigate excitability.

Utero-tubal Embryo Transfer and Vasectomy in the Mouse Model

Utero-tubal embryo transfer uses the utero-tubal junction as a barrier to prevent the embryo outflow that may occur when performing uterine transfer. Vasectomized males are required to obtain pseudopregnant recipients for embryo transfer. Both techniques are discussed.
FAQs
Maternal, placental, and fetal factors must be considered together because development is shaped by their interactions. The placenta and maternal environment can influence the signals, genes, and nutrients reaching growing organs and tissues, while fetal development can be evaluated within that physiological setting. This integrated view helps developmental biologists identify influences that isolated models may not capture.
Keeping development within the uterus retains maternal and placental context, along with physiological conditions surrounding the fetus. By contrast, isolated or ex utero models may not reproduce those interactions. The comparison is valuable when researchers need to determine whether a developmental change reflects a direct biological mechanism or an influence arising from maternal or placental conditions.
Interpretation requires linking observed developmental changes to the specific factor being examined, such as a signal, gene, nutrient, or environmental exposure. Maternal health and developmental timing also provide important context. Considering these variables together helps researchers relate changes in organs or tissues to conditions present during gestation rather than treating fetal development as an isolated process.
Prenatal imaging can monitor development, tissue sampling can provide material for examining developing organs and tissues, and controlled manipulation can test the effects of a selected condition. The appropriate approach depends on whether the goal is observation, direct tissue assessment, or evaluation of how a signal, gene, nutrient, or exposure influences development.
These approaches support investigation of congenital disorders, developmental timing, prenatal therapies, and the effects of maternal health or environmental conditions on offspring outcomes. Their value is greatest when the research question depends on events occurring during gestation, including how a developing organ responds to changing maternal, placental, or physiological conditions.
Controlled manipulation allows researchers to alter or examine a selected developmental influence while the embryo or fetus remains connected to the maternal and placental setting. This can help evaluate how particular signals, genes, nutrients, or environmental exposures affect growing organs and tissues. The resulting observations support more focused interpretation of developmental mechanisms and potential prenatal interventions.
