Transplanting cultured skin sheets improved acne scars in four patients.

Hair follicle-derived sheets can effectively treat vitiligo by repigmenting skin.

Nonpalmoplantar skin cells can be made to express keratin 9 by interacting with palmoplantar fibroblasts.

Scientists created three types of structures to help regrow hair follicles, and all showed promising results for hair regeneration.

Hair follicle stem cells can become corneal-like cells, potentially helping restore vision.

The study found that certain three-dimensional scaffolds can help regenerate hair effectively.

HAP-cell-sheets improved wound healing in diabetic mice.

Hidradenitis suppurativa lesions have less collagen and elastin but more new blood vessels.

Cellular flows and tissue mechanics guide feather follicle formation in birds.

New skin substitutes for treating severe burns and chronic wounds are being developed, but a permanent solution for deep wounds is not yet available commercially.

Hair follicle stem cells can become corneal-like cells with the right environment.

Human stem cells can turn into functional eye cells that might help treat retinal diseases.

Growing hair follicles have high mitochondrial activity and ROS in specific regions, aiding hair formation.

Keratinocytes from dog hair follicles can create a functional skin layer in a lab model, useful for dog skin therapy.

Skin organoids can mimic human skin responses to injury and inflammation, making them useful for studying skin diseases and testing treatments.

High doses of rosemary extract can harm the liver, kidneys, and reproductive organs in young rats.

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

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.

Electrospun matrices help regenerate skin and hair follicles using PCL and collagen scaffolds.

Mast cells and VEGF contribute to post-surgery adhesions, and blocking VEGF can reduce these adhesions; also, certain factors affect wound healing and fetal skin heals differently with age.

The conclusion is that using light-sheet fluorescence microscopy with a special solution can effectively create detailed 3D images of human skin for dermatological research.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Adult stem cells with Tp63 can form hair and skin cells when placed in new skin, showing they have hidden abilities for skin repair.

Environmental cues can change the fate and function of epithelial cells, with potential for cell therapy.

Wnt ligands are crucial for hair growth and repair.

Aminopterin strongly suppresses epithelial tissues and can treat certain skin conditions but has significant side effects.

PSU are better than THF at regenerating skin layers in lab models.

Aminopterin effectively improves skin conditions but has toxic side effects that need careful monitoring.
