Scientists restored fertility in male mice lacking a key fertility gene by using a modified gene.

Hair follicle cells can become bone-like cells, useful for bone repair.

Genetically modified sheep with more β-catenin grew more wool without changing the wool's length or thickness.

Researchers created immortal human skin cells with constant testosterone receptor activity to study hair loss and test treatments.

Nestin marks cells that can become a specific type of skin cell in hair follicles of both developing and adult mice.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Certain immune cells in the skin release a protein that stops hair growth by keeping hair stem cells inactive.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Epidermal signaling helps regenerate fingertip tissue.

Skin cancer often starts from Lgr5+ progenitor cells.

Blocking BMP signaling causes hair loss and disrupts hair growth cycles.

Transplanted bone marrow cells actively move, form clusters, and grow after transplantation.

Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

NF-κB is crucial for zebrafish heart repair, affecting heart cell growth and repair processes.

A standardized drug development platform is essential for efficient and effective drug repurposing, especially during pandemics.

Feather patterns in birds are shaped by signaling interactions and cell movements, with EDA/EDAR crucial for pattern formation.

Fat cells in the skin help start healing and form important repair cells after injury.

Notch1 helps skin heal by attracting specific immune cells.

NAC1 controls certain enzymes that reduce root hair growth in Arabidopsis.

Skin-derived precursors in hair follicles come from different origins but function similarly.

Adult stem cells with Tp63 can form hair and skin cells when placed in new skin, showing they have hidden abilities for skin repair.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

Hair follicle stem cells can turn into many cell types and may help repair nerve damage and have other medical uses.

White lupin uses specific genes to grow root hairs and access phosphorus when it's scarce.

GLI2 increases follistatin production in human skin cells.

Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.

Advanced therapies like gene, cell, and tissue engineering show promise for hair regrowth in alopecia, but their safety and effectiveness need more verification.

CD201+ fascia progenitors are essential for wound healing and could be targeted for treating skin conditions.

Pigs without the Hairless gene showed skin and thymus changes, useful for studying human hair disorders.
