High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

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

Axolotls regenerate their spinal cord through a signal that recruits cells, influenced by cell sensitivity and signal spread.

The research found that a protein called PPARg is important for the formation and healing of sebaceous glands, which can regenerate independently from hair follicles.

Erk signaling helps zebrafish fins regrow to the right size by using memory of the original size.

Zebrafish regenerate sensory hair cells through three phases, offering insights for potential mammal applications.

Epidermal stem cells help heal severe skin wounds and have potential for medical treatments.

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

Spiny mice can regenerate tissues instead of forming scars.

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

Wnt genes help starfish regrow arms by aiding wound healing and cell development.

A specific molecular switch, driven by MAPK/ERK signaling, helps spiny mice heal wounds by regenerating skin instead of forming scars.

Hair follicle stem cells help maintain skin health after injury.

Hair follicles repair 3D injuries using a 2D healing process.

Disrupting a specific protein's function in hair follicle stem cells triggers their activation and a self-healing process.

Fraser's Dolphin can heal skin wounds with minimal scarring, unlike humans.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

Hair follicle stem cells can return to their original niche and help regenerate hair.

Hair follicles can regenerate after radiation damage but not during a specific growth phase.

One type of progenitor cell can maintain normal skin in mice.

A specific group of stem cells can help regenerate hair continuously.

Hair stem cell regeneration is controlled by signals that can explain different hair growth patterns and baldness.

Dermal fibroblasts have adjustable roles in wound healing, with specific cells promoting regeneration or scar formation.

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.

Combining biochemical, immune, and mechanical signals can improve skin regeneration.

Epidermal stem cells help renew skin and regenerate hair follicles.

Hair follicles and deer antlers regenerate similarly through stem cells and are influenced by hormones and growth factors.
