In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Colorectal cancer development involves both genetic changes and epigenetic alterations like DNA methylation and microRNA changes.

Key genes and pathways involved in thyroid eye disease were identified, aiding potential treatment and diagnosis.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

The study found that diseases can be grouped by symptoms and that the accuracy of predicting disease-related genes varies with the data source.

Estrogens generally inhibit hair growth and improve skin quality, but their exact effects on hair follicles are complex and not fully understood.

Hepatitis C virus can cause skin diseases and dermatologists play a crucial role in identifying these conditions.

Blocking the FGF5 gene in sheep leads to more fine wool and active hair follicles due to changes in certain cell signaling pathways.

Hair loss is linked to heart disease and metabolic syndrome, and while current treatments vary in effectiveness, more research is needed for better solutions.

New treatments and diagnostic methods for various animal skin conditions showed promising results.

Conditioned medium from keratinocytes can improve hair growth potential in cultured dermal papilla cells.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Nanocarriers with plant extracts show promise for safe and effective hair growth treatment.
