Immune cells help regulate hair growth, and better understanding this can improve hair loss treatments.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

Fetal-maternal stem cells in a mother's hair can help with tissue repair and regeneration long after childbirth.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

The Hairless gene is crucial for hair cell development, affecting whether skin cells become hair or skin and oil gland cells.

Scientists made working hair follicles using stem cells, helping future hair loss treatments.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

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.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

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

Lung repair involves both dedicated and flexible stem cells, important for developing new treatments.

Fat cells are important for tissue repair and stem cell support in various body parts.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Trichostatin A helps restore hair-growing ability in skin cells used for hair regeneration.

3D bioprinting could improve skin repair and treat conditions like vitiligo and alopecia by precisely placing cells.

Hair graying is influenced by factors like nerves, fat cells, and immune cells, not just hair follicles.

Nestin marks cells that can become a specific type of skin cell in hair follicles of both developing and adult mice.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

A hydrogel made from pig fat helps wounds heal faster by regenerating skin fat cells.

The skin has multiple layers and cells, serves as a protective barrier, helps regulate temperature, enables sensation, affects appearance, and is involved in vitamin D synthesis.

KLF4 is important for maintaining stem cells and has potential in cancer treatment and wound healing.

Plasmalogens activate a channel in cells that may stimulate hair growth.

Cow milk sugars increase fat production and inflammation in skin oil cells.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

Nestin identifies specific progenitor cells in hair follicles that can become outer root sheath cells.

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.
