This study describes a method using lentivirus in mouse cells to analyze epithelial-mesenchymal signaling important for hair follicle development, offering a quicker alternative to genetic models.

This study found that ovine dermal papilla cells exhibit robust aggregation in culture, offering a model to investigate the regulation of hair follicle dermal papilla size.

This study found that modulating epithelial and mesenchymal cell interactions in vitro enabled nearly 100% efficient induction of hair follicles, suggesting potential applications for understanding and testing hair growth and graying.

This study reported that distinct stem/progenitor populations in the ocular surface epithelium have different cell division frequencies and respond differently to injury, with specific spatial compartmentalization and migration behaviors.

This study introduced a theoretical model suggesting that the morphological transition from bud to cap in tooth germ development is driven by mechanical interactions among cells.

This study developed an in vitro 3D organoid model using dermal papilla spheroids and found that it enhances growth factor expression and extracellular matrix production, which could aid drug screening for hair regeneration.

This study found that a skin-like structure can be generated in vitro by implanting early passage hair follicle bulb cells into collagen/chitosan porous scaffolds.

This study established a standardized in-vitro 3D skin model using adult diseased skin cells to investigate the underlying mechanisms of small fiber neuropathies, providing a foundation for further research into their pathophysiology.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

Mouse tail skin has different keratinization near hair follicles and scales.

In this study, upper-bulge epidermal stem cells in mouse hair follicles were shown to play a role in forming tactile sensory units by creating an extracellular matrix that supports nerve interactions.

This study provides evidence that human sweat gland myoepithelial cells contain stem cells capable of self-renewal and differentiating into sweat gland luminal cells.

Healthy mitochondria in skin cells are essential for proper hair growth and skin cell interaction in mice.

This study demonstrated that decellularization of rat lungs effectively removed cellular material while preserving the 3D extracellular matrix, which may aid future human lung tissue engineering.

In this study, researchers observed that dormant TRP-2+ melanoma cells in bone marrow can interact with CD8+ T cells in tumor-bearing ret transgenic mice, potentially influencing immune responses.

This study identified key cells and pathways needed for the development of touch receptor patterns in mouse skin, notably that certain keratinocytes are crucial for innervation patterns, while Merkel cells and BMP signaling have distinct roles.

This study discovered a conserved "fiber-like-motif" of melanosomes aligned in hair across various mammalian species, shedding light on the internal structure that influences hair's thermal and mechanical properties.
