Skin organoids can regenerate hair by forming specific cell units with certain signals.

This study found that human placental extract promoted hair growth and influenced cellular pathways in vitro and rat models, suggesting potential for future hair loss treatments.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This study found that engineered reconstituted skin can form morphogenetic units that promote tissue patterning and hair regeneration, with certain signaling pathways restoring this ability in adult and fetal cells.

This study suggests that CTHRC1, a protein expressed in cardiac fibroblasts, may improve wound repair and prevent cardiac rupture after myocardial infarction by activating a specific signaling pathway.
