Sex neurosteroids cause different effects on hippocampal synaptic plasticity in males and females.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

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

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

Skin cells called dermal fibroblasts are important for skin growth, hair growth, and wound healing.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Stem cell niches are adaptable and key for tissue maintenance and repair.

The conclusion is that grasping how cells determine their roles through evolution is key, with expected progress from new research models and genome editing.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Disruptions in hair follicle fibroblast dynamics can cause hair growth problems.

Transplanted hair follicles can change and adapt to new areas of the body, with the immune system possibly playing a role in this adjustment.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

Skin organoids are a promising new model for studying human skin development and testing treatments.

Environmental cues can change the fate and function of epithelial cells, with potential for cell therapy.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

Epithelial stem cells can adapt and help in tissue repair and regeneration.

Dermal adipose tissue in mice can change and revert to help with skin health.

Different types of skin cells play specific roles in development, healing, and cancer.

Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.

The conclusion is that understanding how feathers and hairs pattern can help in developing hair regeneration treatments.

Finasteride reduces new brain cells in male mice, possibly causing depression.

The review concludes that innovations in regenerative medicine, tissue engineering, and developmental biology are essential for effective tissue repair and organ transplants.

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