Chemotherapy in the first trimester of pregnancy is risky, but in the second and third trimesters, it's generally safe with careful drug selection and timing.

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

Blocking Wnt signaling in young mice causes thymus shrinkage and cell loss, but recovery is possible when the block is removed.

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

Good feather growth in poultry needs the right balance of proteins, amino acids, minerals, and vitamins.

Not having enough or having too much of the protein Grainyhead-like 3 leads to various developmental problems.

Auxin and ethylene hormones both work together and against each other to control plant growth.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

Different skin stem cells help heal wounds, with hair follicle cells becoming more important over time.

Regenerative pharmacology, which combines drugs with regenerative medicine, shows promise for repairing damaged body parts and needs more interdisciplinary research.

Human hair follicle dermal cells can effectively replace other cells in engineered skin.

MALDI Imaging Mass Spectrometry is a useful method for studying skin conditions, but sample preparation is crucial for accurate results.

PBX1 helps hair stem cells grow and change by turning on certain cell signals and preventing cell death, which may be useful for hair regrowth treatments.

Using stem cells from fat tissue can significantly improve wound healing in dogs.

3D cell-derived matrices improve tissue regeneration and disease modeling.

Scientists have made progress in understanding hair follicle stem cells, identifying specific genes and markers, and suggesting their use in treating hair and skin conditions.
