Certain inhibitors slow down plant growth by causing early cell specialization without changing the cell development pattern.

Fish teeth and taste bud densities are linked and can change between types due to shared genetic and molecular factors.

The exact identity of skin stem cells and how skin cells differentiate is not fully known.

Male pattern hair loss may be linked to the developmental origins of hair follicles.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Eph/ephrin signaling is important for skin cell behavior and could be targeted to treat skin diseases.

The skin's basement membrane has specialized structures and molecules for different tissue interactions, important for hair growth and attachment.

BMP4-related anomalies can cause a wide range of eye, brain, and hand/foot problems, and new cases show this variability.

A protein called FERONIA helps control root hair growth in response to cold and low nitrogen by activating nutrient-sensing pathways in a plant called Arabidopsis.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

Keratinocytes show more TGF-β system activity and collagen production as they age, which might affect wound scarring.

P-cadherin is important for hair growth and health, and its problems can cause hair and skin disorders.

The skin's basement membrane is specially designed to support different types of connections between skin layers and hair follicles.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

Lizards can regrow their tails, and studying this process helps understand scar-free healing and limb regeneration.

The hair follicle is a great model for research to improve hair growth treatments.

The conclusion is that understanding how feathers and hairs pattern can help in developing hair regeneration treatments.

Hair patterns in mice are controlled by both a global system dependent on Fz6 and a local self-organizing system.

Turing patterns are now recognized as important in developmental biology.

Skin needs dermal β-catenin activity for hair growth and skin cell multiplication.

Cells from certain embryo parts can induce head formation in another embryo, involving complex signaling pathways.

Msx and Dlx genes are crucial for development, controlling cell behaviors like growth and differentiation through their roles as gene regulators.

Abnormal scalp whorls can indicate brain development issues but may also be seen in neurologically normal people.

Lizards can regrow their tail scales with the same structure, distribution, and gender-specific features as the original ones, and this unique ability is not seen in adult mammals.

Sensory neuron and Merkel cell changes in the skin happen independently during normal skin maintenance.

Scientists improved how to make skin-like structures from stem cells using special gels and a device that controls growth signals, leading to better hair and skin features.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

The study found that the protein Dkk4 helps regulate hair growth by controlling Wnt signaling in mice.

Scientists have made progress in growing mini-organs and regenerating parts of the skin, with plans to treat hair loss in a future trial.
