The neonatally maturing pituitary harbors an activated stem cell compartment and shows prominent regenerative capacity, as revealed by single-cell transcriptomic profiling and in vitro (organoid) and in vivo (mouse) exploration.

Mutations causing proinsulin misfolding trigger unfolded protein response and lead to impaired proliferation and reduced mTORC1 signalling of developing beta-cells in a patient-derived induced pluripotent stem cell disease model.
Normalizing Tcf4 expression during early postnatal development improves behavioral outcomes in Pitt-Hopkins syndrome (PTHS) model mice, suggesting that genetic therapies are feasible in individuals with PTHS.

At the transition from intrauterine to postnatal life, drastic environmental alterations are mirrored by changes in cellular immunity, which are in part immune cell intrinsic and have lasting health impact.
A single-nucleus transcriptomic atlas reveals the molecular signatures and trajectory dynamics of the neurogenic lineage in the human hippocampus during neonatal development, adulthood, aging, and after injury.

Age-specific transcriptional responses to Flt3-ITD and cooperating Flt3/Runx1 mutations cause hematopoietic stem cell depletion and myeloid progenitor expansion during adult, but not fetal/neonatal, stages of development.
