Drug repurposing speeds up development, cuts costs, and uses known safe drugs, but faces challenges like regulations and patents.

Exosomes may be more effective than PRP for hair restoration.

New treatments for hair loss should target eight main causes and use specific plant compounds and peptides for better results.

The document concludes that drug repurposing, which is reusing known medicines for new illnesses, can provide faster, cheaper treatment options for various serious diseases, including cancer, COVID-19, and rare diseases.

Latanoprost-loaded nanotransfersomes could help treat hair loss by promoting hair growth.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

New treatments for skin damage from UV light using stem cells and their secretions show promise for skin repair without major risks.

The document concludes that stem cell therapies lack solid proof of effectiveness, except for blood system treatments, and criticizes the ethical issues and commercial exploitation in the field.

Stem cells from hair follicles in a special gel show strong potential for bone regeneration.

MicroRNAs are crucial for controlling skin development and healing by regulating genes.

The research showed how melanocytes develop, move, and respond to UV light, and their stem cells' role in hair color and skin cancer risk.

Human body's immune cells are more common in the layer of fat just beneath the skin than in deeper fat layers.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.

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

Researchers found a safe and effective way to pick genetically modified skin cells with high growth potential using CD24.

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.

Vav2 changes how hair follicle stem cells' genes work as they age, which might improve regeneration but also raise cancer risk.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Activin B improves wound healing and hair growth by helping stem cells move using certain cell signals.

The technique allowed noninvasive tracking of hair stem cell survival and growth, showing potential for hair loss research.

Porphyra-334 may help reduce wrinkles and promote hair growth.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

Certain human skin cells marked by CD44 and ALDH are rich in stem cells capable of long-term skin renewal.

Metformin helps improve skin regeneration by increasing the growth of skin stem cells.

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

Fat tissue stem cells show promise for repairing different body tissues and are being tested in clinical trials.

Targeting colon cancer stem cells might lead to better treatment results.

Different cell types work together to repair skin, and targeting them may improve healing and reduce scarring.

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

Different parts of the body's fat tissue have unique cell types and characteristics, which could help treat chronic wounds.
