Cavity macrophages gather on organ surfaces but don't really invade or help repair the organs after injury.

The hydrogels help harvest cells while preserving their mechanical memory, which could improve wound healing.

Hair follicle stem cells could be used to treat the skin condition vitiligo.

Cell size controls when stem cells divide.

Disrupted cholesterol production impairs hair follicle stem cells, leading to hair loss.

Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.

Increasing Smurf2 hinders hair follicle stem cell differentiation and wound healing.

Older hair follicle stem cells have a reduced ability to renew themselves, leading to more hair loss.

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

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Different types of stem cells and their environments are key to skin repair and maintenance.

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.

Adult fibroblasts help heart cells mature and improve heart function.

Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.

Muscles and nerves that cause goosebumps also help control hair growth.

Tcf3 helps cells move and heal wounds by controlling lipocalin 2.

miR-22, a type of microRNA, controls hair growth and its overproduction can cause hair loss, while its absence can speed up hair growth.

Hormones during pregnancy and lactation keep skin stem cells inactive, preventing hair growth.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

Cell division orientation varies by body site and is linked to epidermal thickness and cell density.

CIP/KIP proteins help stop cell division and support hair growth.

Gata6 is important for protecting hair growth cells from DNA damage and keeping normal hair growth.

Skin-derived stem cells can become various cell types, including germ cell-like and oocyte-like cells.

The document concludes that understanding how adult stem and progenitor cells move is crucial for tissue repair and developing cell therapies.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

The new patch made of cell matrix and a polymer improves wound healing and supports blood vessel growth.

New treatments targeting the Hedgehog pathway can help treat advanced skin cancer but may have side effects and their effectiveness in early stages is unknown.

Ionizing radiation causes irreversible skin damage, with single doses leading to acute injury and hair graying, and fractional doses causing more severe long-term tissue damage.
