This summary reports that γδ T cells play a role in regulating hair follicle formation during wound healing in adult skin.

This review discusses the role of Hedgehog signaling in epidermal and hair follicle development and its involvement in basal cell carcinoma, without reporting new empirical findings.

This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.

This study suggests that heparan sulfate is crucial for regulating hair follicle formation, cycling, and gland morphogenesis, with its ablation leading to continuous hair growth and increased gland activity in mice.

In this review, researchers summarize key factors in constructing skin organoids, including cell source and assembly methods, and emphasize advances such as air-liquid interface culture for improving tissue development, aiming to guide standardized protocols and future clinical applications.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

In this study, researchers successfully derived skin organoids from mouse pluripotent stem cells that spontaneously produce hair follicles, potentially aiding in hair growth research and in vitro drug testing.

This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.
