In a new study published in Cell, researchers from Stowers Institute of Medical Research have developed an AI model named RegVelo that bridges two critical aspects of single-cell biology: estimating cellular changes over time and inferring the gene regulatory networks that govern these transformations. This innovative approach could significantly enhance the development of cell therapies in regenerative medicine.
Traditionally, cellular development has been viewed as a series of static snapshots. However, RegVelo models the dynamics of cell fate decisions, revealing how gene regulatory networks operate over time and space. For instance, in zebrafish neural crest development, the model identified key regulators of pigment cell fate, offering insights that may extend to various developmental and oncological contexts.
According to Alejandro Sánchez Alvarado, Stowers President and chief scientific officer, RegVelo’s implications are far-reaching, applicable beyond neural crest cells to any system where cellular changes occur. This model not only describes developmental processes but also generates biologically meaningful hypotheses that can be experimentally validated, thereby advancing our understanding of cellular dynamics and regulatory interactions.
