In this study, researchers analyzing human fetal skin fibroblasts found eight distinct populations with developmental stage-specific abundance, identifying markers linked to fibroblast functions in blood vessel development, dermal layers, and hair follicle maturation.

This study identified a proliferative intermediate transcriptional state associated with the transition from secondary hair germ cells to lower hair follicle-associated cells during early hair follicle regeneration in mice.

This article reviews various models of graft-versus-host disease, highlighting the complexity of its mechanisms and the challenges in interpreting histopathologic data; it reports no new results.

This study observed that the ontogenetic transition from scarless repair in early fetal rat wounds to scar-forming repair in late gestation is associated with differential TGF-β ligand and receptor expression patterns.

This study highlights the role of innate immunity and purinergic signaling in regulating hematopoiesis and hematopoietic stem/progenitor cell specification. The researchers observed that these ancient pathways operate both paracrinally and autocrinally within HSPCs, maintaining their developmental function throughout evolution.

In this study, the researchers observed that the expression of certain growth factors and their receptors increases with gestational age, implying a role in skin development, structure maintenance, and wound healing.
