Long COVID causes a wide range of long-lasting symptoms that change over time and are hard to diagnose and treat.

Hair follicle development in cashmere goats involves dynamic changes in proteins and metabolites, with key roles for oxytocin, MAPK, and Ca2+ pathways.

FERONIA and LRX proteins help control cell growth in plants by regulating vacuole expansion.

Myc activation reduces skin stem cells by affecting cell adhesion.

Both cell and non-cell parts are important for rat whisker follicle regrowth.

Mice can regrow hair on wounds due to specific cell interactions and mechanical forces not seen in rats.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Older people's sweat glands are less effective at helping skin wounds heal due to weaker cell connections.

The skin basement membrane is specialized for different tissue interactions, important for hair growth and attachment.

Stem cell niches regulate the number and function of stem cells in the body.

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.

Wound healing involves three phases and various cells and factors, with scars typically forming in adults. Chronic wounds can occur due to various issues, and abnormal scarring can lead to hypertrophic or keloid scars. Emerging research areas include the role of proteins, microRNAs, macrophage manipulation, and stem cell treatment.

Concentrated nanofat helps mice grow hair by activating skin cells and may be used to treat hair loss.

Improving the environment and cell interactions is key for creating human hair in the lab.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

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

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

A new hydrogel made from human cells improves wound healing by working with immune cells to promote repair.

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

Biomimetic scaffolds are better than traditional methods for growing cells and could help regenerate various tissues.

Melatonin helps Cashmere goats grow more hair by affecting certain genes and cell pathways.

Hair growth can be stimulated by combining certain skin cells, which can rejuvenate old cells and cause them to specialize in hair follicle creation.

Aged individuals heal wounds less effectively due to specific immune cell issues.

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.

The document concludes that better targeted treatments are needed for wound healing, and single-cell technologies may improve cell-based therapies.

The African spiny mouse heals skin without scarring due to different protein activity compared to the common house mouse, which heals with scarring.

The osteopontin gene is active in a specific part of rat hair follicles during a certain hair growth phase and might affect hair cycle and diseases.

Aging skin is affected by inflammation, reduced stem cell function, and slower wound healing.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Researchers developed a 3D model of human hair follicle cells that can help understand hair growth and test new hair loss treatments.
