Gene expression is a fundamentally stochastic process, with randomness in transcription and translation leading to cell-to-cell variations in mRNA and protein levels. This variation appears in organis...

Embryonic development typically requires precise coordination among cells to achieve reproducible outcomes, leading to the assumption that cellular heterogeneity must be minimized or buffered against....

Bolondi, Law, et al. engineer a single-cell recorder to reconstruct progenitor dynamics within mouse stem cell-derived embryoids. They characterize the variable fates of axial progenitors as they cont...
