Electroporation of Craniofacial Mesenchyme

Craniofacial cartilages develop in close contact with other tissues and are difficult to manipulate in live animals. We are using electroporation to deliver molecular tools during growth of the craniofacial skeleton while bypassing early embryonic effects. This approach will allow us to efficiently test candidate molecules in vivo.

Intrinsically Disordered Proteins

Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...
FAQs
Neural crest cell migration is one of the embryonic processes that shapes craniofacial structures. Genetic variants that interfere with this movement can alter where developing cells contribute to the skull, face, jaw, or related tissues. The resulting abnormalities may differ among individuals because migration interacts with later developmental events, including tissue differentiation and the fusion of embryonic structures.
After cells reach appropriate locations, tissue differentiation helps establish distinct craniofacial structures, while fusion joins developing components into continuous anatomical forms. Variants affecting either process can produce different structural patterns, including those associated with cleft lip and palate. Examining these mechanisms helps connect a visible congenital finding with the developmental stage and biological process that may have been disrupted.
Some congenital craniofacial disorders are associated with recognizable inheritance patterns, meaning genetic information may help explain why a condition occurs within a family. Others arise sporadically, without a clearly inherited pattern. Distinguishing these possibilities matters because the underlying explanation affects genetic diagnosis and how clinicians approach recurrence-risk counseling for affected individuals and their relatives.
These disorders link genetic variation with visible changes in structures formed during embryonic development. Studying conditions such as cleft lip and palate or craniosynostosis can therefore reveal how neural crest cell migration, tissue differentiation, and embryonic fusion contribute to normal craniofacial formation. The same work supports broader understanding of developmental biology while clarifying the molecular basis of congenital abnormalities.
Genetic diagnosis can help identify a molecular basis for a craniofacial condition when one is present. That information may clarify whether the disorder follows a recognizable inheritance pattern or appears sporadically, which directly informs recurrence-risk counseling. It also gives clinicians and families a more precise framework for understanding the condition and planning individualized clinical care.
Research connects molecular and developmental findings with clinical management. By clarifying how particular developmental processes are disrupted, investigators improve understanding of conditions that may affect appearance, breathing, feeding, hearing, or speech. This knowledge informs individualized care and contributes to surgical and regenerative approaches, while continuing to expand the scientific understanding of craniofacial development.
