Reprogramming cells and tissue patterning via bioelectrical pathways: molecular mechanisms and biomedical...

Area of Science:

• Developmental Biology
• Regenerative Medicine
• Bioelectricity

Background:

• Current regenerative medicine focuses on cellular reprogramming.
• Cellular behavior and morphogenesis are influenced by transcriptional and biochemical factors.
• Emerging evidence highlights the role of bioelectrical properties in cell processes.

Purpose of the Study:

• To explore the role of endogenous bioelectrical gradients in large-scale anatomical shape control.
• To investigate how transmembrane voltage potentials (Vmem) act as instructive cues in morphogenesis.
• To demonstrate the potential of modulating bioelectric signals for tissue and organ regeneration.

Main Methods:

• Utilizing genetic and pharmacological techniques to modulate bioelectric gradients in vivo.
• Analyzing the influence of altered bioelectric potentials on cell differentiation, proliferation, and migration.
• Observing the effects on organogenesis, tissue identity, and appendage regeneration.

Main Results:

• Bioelectrical properties profoundly influence cell differentiation, proliferation, and migration.
• Spatiotemporal gradients of transmembrane voltage potentials (Vmem) provide patterning cues for large-scale anatomy.
• Modulation of bioelectric gradients can initiate organogenesis, alter tissue identity, and trigger regeneration.

Conclusions:

• Bioelectrical signals are crucial for orchestrating cellular programs toward anatomical development.
• Understanding and manipulating the bioelectric code can revolutionize regenerative medicine, developmental biology, and bioengineering.
• This electrical information processing in non-neural tissues parallels neural network functions.
