Keloid scars may form due to changes in skin cell characteristics and specific protein signaling.

The best method for urethral reconstruction is using hypoxia-preconditioned stem cells with autologous cells on a vascularized synthetic scaffold.

Foxp3+ Regulatory T Cells are important for immunity and tolerance, affect hair growth and wound healing, and their dysfunction can contribute to obesity-related diseases and other health issues.

Unconventional lymphocytes are important for quick immune responses and healing of skin and mucosal barriers.

3D bioprinting is useful for making tissues, testing drugs, and delivering drugs, but needs better materials, resolution, and scalability.

Using gelatin sponges for deep skin wounds helps bone marrow cells repair tissue without scarring.

Xeno-free three-dimensional stem cell masses are safe and effective for improving blood flow and tissue repair in limb ischemia.

Growth factors-rich plasma treatments can significantly speed up wound healing and tissue regeneration.

Activating TLR9 helps heal wounds and regrow hair by using specific immune cells.

PlacMA hydrogels from human placenta are versatile and useful for cell culture and tissue engineering.

Keratin hydrogels from human hair show promise for tissue engineering and regenerative medicine.

Advancements in tissue engineering show promise for hair follicle regeneration to treat hair loss.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

Fibroblast Growth Factors (FGFs) are important for tissue repair and regeneration, influencing cell behavior and other factors involved in healing, and are crucial in processes like wound healing, bone repair, and hair growth.

The conclusion is that certain scalp tissue changes are characteristic of lichen planopilaris, with mucinous perifollicular fibroplasia being a new feature for diagnosis.

Large-scale fibronectin nanofibers help heal wounds and repair tissue in a skin model of a mouse.

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.

Conditioned media from mesenchymal stem cells show promise for tissue repair and disease treatment, but more research is needed on their safety and effectiveness.

The study found that the cause of alopecia areata can be identified through tissue analysis, and vertical sections are enough for diagnosis.

Newly born mesenchymal cells quickly spread out in response to tissue tension during early development.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

Wounds can regenerate hair in young mice, but this ability declines with age, offering insights for improving tissue regeneration in the elderly.

Exosomes could be effective for improving skin health and treating skin diseases.

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.

Lichen planopilaris is the most common type of scarring hair loss observed, with a variety of symptoms and tissue changes.

A special hydrogel helps heal skin without scars and regrows hair.

Turning scar-forming cells into fat cells can reduce scarring.

Hair loss due to scarring can be treated by reducing inflammation, removing scar tissue, and transplanting hair. The Follicular Unit Extraction technique is effective but requires skill and time. Future focus should be on scar-less healing methods.

Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.

Trichoscopy is a non-invasive way to diagnose hair and scalp problems without needing hair samples.
