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

Two-photon microscopy effectively tracks live stem cell activity in mouse skin with minimal harm and clear images.

New imaging techniques show testosterone delays hair growth and shrinks follicles in mice, but have limited depth for viewing.

Hair properties change under electromagnetic fields and are influenced by individual characteristics and the environment.

Light can be used to stimulate ear hair cells, improving speed and consistency over previous methods.

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

Radiation therapy is an effective treatment for severe scalp cellulitis with mild side effects and no long-term complications.

3D-printed mesoporous scaffolds show promise for personalized drug delivery with controlled release.

The study showed that some hair follicle stem cells wake up to grow hair while others stay asleep, and that the environment around them is important for hair growth.

Topical glucocorticoids thin the skin and change collagen structure.

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

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

Merkel cells stabilize nerve endings in the skin, and they change independently of each other.

Stem cells control their future role by changing ERK signal timing, affecting tissue regeneration and cancer.

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.

Hair grows when stem cell offspring in the follicle base proliferate, influenced by the dermal papilla.

High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.

Heavy ions cause significant damage to rabbit forebrains, similar to other radiation effects.

Lasers can reduce hair growth but may also damage skin.

LED-LLLT helps heal wounds, reduce pain, and regrow hair using specific light wavelengths.

New methods have greatly improved our understanding of stem cell behavior and roles in the body.

Certain proteins help nerve cells branch, and other findings relate to cancer, stem cell behavior, and cell division.

Light-based treatment, Photobiomodulation, shows promise for non-invasive skin therapy with few side effects.

Curly and straight hair differ in how their internal fibers are arranged.

The study introduced a new imaging technology to track skin healing and bone marrow cell activity over time.

Stem cell therapies show promise for treating various diseases but face challenges in clinical use and require better monitoring techniques.

3D imaging of skin biopsies offers better accuracy but is time-consuming and can't clear melanin.

The study found that combining SHG and OCT effectively monitors skin wound healing in mice.
