The document concludes that careful design of genetic fate mapping experiments is crucial for accurate cell lineage tracing in mice.

The enzyme 5α-reductase is key in causing psychotic-like effects from sleep deprivation.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.

Nuclear Factor I-C is important for controlling hair growth by affecting the TGF-β1 pathway.

The model showed that randomness accurately describes individual hair growth cycles and that synchronization can cause large fluctuations not seen in humans.

Telogen is an active phase with important biological processes, not a resting phase.

A special environment is needed to fully activate sleeping stem cells.

Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.

The Notch signaling pathway helps in mouse hair development through a noncanonical mechanism that does not rely on RBPj or transcription.

Using a fractional laser can stimulate hair growth, but the intensity and duration of inflammation are crucial. Too much can cause ulcers and scarring. Lower beam energy and fewer treatments are recommended to avoid damage.

Mice lacking steroid 5α-reductase 2 show less aggression and better impulse control.
