This study found that androgen signaling has complex effects on bone formation in male AR3.6-transgenic mice, with varying impacts based on the embryonic lineage of cells.

In this viewpoint, researchers discussed the possible role of the developmental origin of scalp dermis in influencing the specific pattern of hair follicle miniaturization seen in male pattern hair loss, noting that frontal follicles are more susceptible while occipital follicles remain largely terminal.

This review discusses various types of stem cells used in regenerative medicine, including adult stem cells and induced pluripotent stem cells (iPSCs), and evaluates them based on their embryonic tissue origins to explore new therapeutic approaches.

This study reviews the embryological origins, anatomical and histological structure, and key functions of the skin, emphasizing its protective, sensory, and regulatory roles, as well as the social and psychological impacts of post-lesion changes.

This review discusses the generation of germ cell-like cells from skin-derived stem cells and reports no new results; the potential for these cells to produce viable progeny remains unclear.

This study outlines the complex structure and various functions of the skin, emphasizing its role as a barrier against external insults, a sensory receptor, and its importance in vitamin D synthesis.

This study observed that human dental pulp stem cells can differentiate into adipocytes and osteocytes, but their potential for neural differentiation remains uncertain due to similar responses seen in undifferentiated cells.

This article reviews different perspectives on nevus comedonicus, discussing its classification and potential associations with systemic findings, but it reports no new results.

This study presents a detailed overview of lymphatic vessel development and highlights the role of abnormal lymphangiogenesis in various diseases, suggesting that targeting lymphangiogenic factors may improve treatment strategies.

This study found that skin-derived precursor cells in mice can originate from both neural crest and somite lineages but show functional similarities regardless of their developmental origins.

This study found that the cell of origin in mouse skin affects melanoma phenotype and response to therapies, despite the presence of the same genetic mutations.

This study observed that benign skin tumors were more common than malignant ones, with squamous cell carcinoma being the most frequent type among malignant tumors.

This review discusses the development, lineages, functions, and roles of fibroblasts in fibrosis across four organs, highlighting their capabilities in tissue repair and contributions to fibrotic disorders when aberrantly activated, but it reports no new experimental findings.
