ODC expression in mouse skin and tumors is varied and can be inhibited by retinoic acid or cycloheximide.

A new 3-D bioreactor system improves drug screening and reduces animal testing.

The outer root sheath in hair follicles changes during growth, with different keratinization processes in its layers.

The 3D scaffold helped maintain hair cell traits and could improve hair loss treatments.

Sea cucumbers have unique genes that help them regenerate their intestines.

Transplanted bone marrow cells actively move, form clusters, and grow after transplantation.

Immature hair cells can grow and change into different types of hair cells over time.

Changing the structure of the hair follicle's environment can affect hair quality but doesn't stop hair growth.

Increased ODC activity leads to skin tumors by recruiting stem cells, not by toxic byproducts.

Sostdc1 controls the size and number of hair and mammary gland structures.

Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.

Researchers created a potential skin substitute using a biodegradable mat that supports skin cell growth and layer formation.

Hair, teeth, and mammary glands develop similarly at first but use different genes later.

Stem cells in the eye have different roles and behaviors, helping maintain and repair the eye's surface.

A new gel helps grow mature eggs in a lab that can be fertilized and develop further.

The OVOL1 gene, controlled by β-catenin, is crucial for creating hair follicles.

EVAL membranes help create cell structures that can regrow hair follicles.

Stem and progenitor cells in the eye have different division rates and locations, affecting how they respond to injury.

Scientists improved how to grow mouse skin cells in the lab and created a long-lasting cell line, but didn't fully explain its advantages or compare it to normal cells.

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

Keratinocytes in hair follicles differentiate similarly to skin cells, with specific patterns in different regions.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Fgf20 is crucial for hair follicle formation by influencing cell movement and growth.

The local environment is crucial for cell development in the tongue.

MAEG helps in mouse hair follicle development by aiding cell adhesion.

Sox10 is important for hair follicle development and hair growth cycles.

Corneal cells can transform into skin and hair cells through specific signals.

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.
