Umbilical cord blood is a valuable source of stem cells for medical treatments, but its use is less common than other transplants, and there are ethical issues to consider.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

A new method using a microfluidic device can prepare hair follicle germs efficiently for potential use in hair loss treatments.

Stem cells and their exosomes show promise for repairing tissues and healing wounds when delivered effectively, but more research is needed on their tracking and optimal use.

Fat transplants using a patient's own fat can rejuvenate and repair tissues effectively.

Special gels help heal diabetic foot sores and reduce the risk of amputation or death.

Injectable platelet-rich fibrin has improved healing and regeneration in various medical fields and can be more effective than previous treatments.

Platelet-rich plasma (PRP) shows promise in military medicine but its effectiveness varies.

Mesenchymal stem cells show promise for treating various skin conditions and may help regenerate hair.

Photobiomodulation therapy helps manage cancer treatment side effects but needs more research for optimization.

3D bioprinting improves wound healing by precisely creating scaffolds with living cells and biomaterials, but faces challenges like resolution and speed.

Using mesenchymal stem cells or their exosomes is safe for COVID-19 patients and helps improve lung healing and oxygen levels.

Stem cell-derived conditioned medium is effective in improving hair density and thickness for alopecia treatment.

Platelet lysate effectively promotes hair growth and improves hair thickness in people with androgenetic alopecia.

Stem-cell therapy shows promise for skin conditions but needs more research.

The review suggests that a special cell-derived treatment shows promise for various skin conditions and hair growth but needs more research for confirmation.

Tiny particles called extracellular vesicles show promise for treating skin conditions and promoting hair growth.

The FDA approved the first gene therapy for a blood disorder after overcoming early challenges and demonstrating patient benefits.

Adipose-derived stem cells can help repair and improve eye tissues and appearance.

Exosomes may improve skin, scars, hair growth, and fat grafts in plastic surgery, but more research is needed.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Creating fully functional artificial skin for chronic wounds is still very challenging.

New materials that better mimic natural skin structure could improve healing, especially for chronic wounds.

Transplanted hair follicle stem cells improved brain function and reduced damage after a stroke in rats.

PRP may help with aging and osteoarthritis, improving tissue repair and reducing surgery risk.

New regenerative treatments for hair loss show promise but need more research for confirmation.

Myoblast transplantation shows promise for treating various muscle and heart conditions.

New treatments for hair loss from alopecia areata may include targeting immune cells, using stem cells, balancing gut bacteria, applying fatty acids, and using JAK inhibitors.

PBMCsec can help reduce and improve thick skin scars.

Fluid Platelet-Rich Fibrin (PRF) is more effective and faster at improving acne scars than Platelet-Rich Plasma (PRP), with similar mild side effects.
