Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

3D bioprinting is advancing in plastic and reconstructive surgery, especially for creating tissues and improving surgical planning, but faces challenges like vascularization and material development.

New imaging tools help doctors better examine hair and scalp health without surgery.

Sensory neuron remodeling and Merkel-cell changes in the skin happen independently.

The Orenburg goat breed has unique genetics that require more detailed research and careful breeding.

A specific mutation in Kras causes abnormal tissue changes by making a cell signal continuously active, which disrupts normal cell coordination.

Understanding genetics is crucial for treating heart and skin diseases.

The balance between cell renewal and differentiation controls the growth of cancerous cells in mouse skin.

Society's view of "freaks" has shifted from natural deformities to extreme plastic surgery, reflecting changing beauty standards and pressures.

The document concludes that finasteride can reduce nandrolone detection in doping tests, suggesting frequent testing and setting metabolite level thresholds for detection.

The enzymes Tet1, Tet2, and Tet3 are important for the development of hair follicles and determining hair shape by controlling hair keratin genes.

Non-coding RNA boosts retinoic acid production and signaling, aiding regeneration.

Gray hair affects hair's movement and appearance, making it less bouncy and more wavy.

STIM1 is essential for sweat secretion.

Different levels of shear stress affect where cells move and gather in a 3D-printed model, helping to better understand cell behavior in blood vessels.

The document provides a quiz for physicians to earn continuing medical education credits in facial plastic surgery.

The document concluded that there are differences in hair growth cycles and skin cell turnover rates, which can be measured with electronic equipment.

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

The article concludes that hair restoration techniques must account for ongoing hair loss to ensure successful long-term results.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

The conclusion is that the dermal papilla is crucial for hair follicle regrowth, and hair follicles undergo significant structural changes in addition to cell division during regeneration.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

Ruxolitinib can help regrow hair in severe alopecia areata.

PRC1 influences skin stem cell development by both turning genes on and off, affecting hair growth and skin cell types.
