Friedreich's ataxia causes thin, weak hair with surface damage and cavities.

The Spherical Skin Model improves drug and cosmetic testing by accurately mimicking human skin for efficient compound screening.

Fibroblast-derived growth factors and exosomes can significantly improve skin aging.

Skin problems can be caused or worsened by physical forces and pressure on the skin.

Metal organic frameworks-based scaffolds show promise for tissue repair due to their unique properties.

A wool hair keratin hydrogel is promising for growing cells and tissue engineering.

Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.

Turning scar-forming cells into fat cells can reduce scarring.

Cell growth improved the strength of 3D bioprinted structures.

Collagen scaffolds in cell therapy can transform skin to be more resilient and pressure-responsive.

3D images of skin show collagen is evenly spread, but elastic fibers are fewer near hair follicles.

Intermediate filaments are crucial for cell differentiation and stem cell function.

Two fibroblast types shape skin structure and repair differently.

Stretching wool changes its structure and improves fiber alignment.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

The new 3D sponge-like material helps cells grow and heals wounds effectively.

Skin and its underlying fat layer act together to resist mechanical stress, and reinforcing this composite structure may help more with anti-aging than just strengthening the skin alone.

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.

Combining anti-androgenic, anti-inflammatory, and anti-fibrotic treatments may improve hair loss outcomes, but more testing is needed.

Keratin-based hydrogels with calcium are effective for delivering anti-fibrotic drugs.

Bone-forming cells grow well in 3D polymer scaffolds with 35 µm pores.

Keratin hydrogels can be customized for better tissue healing.

Frontal fibrosing alopecia on limbs shows permanent inflammatory hair loss, not typical scarring.

Strontium zinc silicate may help treat osteoporosis and muscle loss.

5% hydroxyapatite in scaffolds improves bone tissue formation and mechanical properties.

The new wound dressing promotes cell growth and healing, absorbs wound fluids well, and is biocompatible.

Steers with winter hair coats and reduced sweating struggled with heat, leading to less grazing and poor performance.

The rat vibrissa follicle can quickly remodel its basement membrane during hair growth, affecting cell signaling and activity.
