Analysis of zebrafish periderm enhancers illuminates the conserved DNA of epithelial enhancers across species and prioritizes orofacial-cleft-associated regulatory variants near KRT18/KRT8.
In humans, specific sequence features can predict whether meiotic recombination occurs at sites bound by the protein PRDM9, whose DNA-binding zinc-finger domain can unexpectedly bind to gene promoters and to other copies of PRDM9.
The characterization of ancient B19V and HBV genotype A4 viruses circulating during Colonial epidemics provides new insights into the pathogens that were introduced to the Americas after the European colonization.
Parturition gene regulation across multiple cell-types and placental compartments is deciphered at single cell resolution, highlighting the common role of the NFKB pathway in both term and preterm birth.
MicroRNA-based direct conversion of human fibroblasts to neurons is applicable to fibroblasts from donors ranging in age from neonatal to centenarian, allowing the generation of neurons that maintain the age-associated signatures of the starting fibroblasts.
Loss and gain-of-function investigation uncovers a regulatory network controlling human heart chamber specification in which the cardiac precursor gene ISL1 accelerates ventricular induction and antagonizes retinoic acid-driven atrial commitment.
Human yolk sac-like cells, which share characteristics with the post-implantation human hypoblast, can model the interaction between the epiblast and hypoblast that occurs during early human development.
Directed differentiation of stem cells can generate ventral-anterior foregut spheroids that can expand into three-dimensional lung organoids with striking structural, cellular and molecular similarities to the human fetal lung.
