This study observed that dermal dendritic cells migrate to the epidermis in mouse tail and back skin, correlating with changes in epidermal physiology like ortho- and parakeratosis.

In this study, researchers engineered ventral skin organoids (vSkOs) with specific cellular compositions and signaling environments to generate human amnion-like tissues called Amnioids, offering new tools for studying human development and potential regenerative therapies.

In this study using live mice, researchers observed that during hair follicle regression, apoptosis in basal cells may propagate by triggering neighboring cells, potentially regulated by a gradient of pro-survival signals from stem cells, and proposed a testable mechanism to further explore this process.

This study in live mice suggests that hair follicle regression involves apoptosis propagation towards stem cells, potentially slowed by a protective signal from the stem cells themselves.

This study found that Sox2 and BMP signaling may be key regulators of pigmentation and melanocyte migration, as suggested by experiments in mice, human biopsies, and cell co-cultures.

This abstract omits specific findings and does not provide new research results.

This study found that mechanical and chemical interactions in skin organoids are crucial for initiating mesenchymal-epithelial interactions necessary for hair follicle regeneration.

In this study, co-grafting human keratinocytes with murine dermal papilla-enriched cells produced hair follicle-like structures, but without regular hair formation, suggesting anomalous folliculogenesis.

This study suggests that the action of minoxidil in stimulating hair growth likely occurs at the follicular dermal papilla, though it does not induce new follicle formation.

This study reports that hair regeneration in live mice involves spatially regulated stem cell divisions and requires mesenchymal interactions, observed in real-time using a novel non-invasive imaging method.
