Microneedles are effective for painless drug delivery and promoting wound healing and tissue regeneration.

Researchers found a new way to create hair-growing structures in the lab that can grow hair when put into mice.

Chick embryo extract helps rat hair follicle stem cells potentially turn into Schwann cells, important for the nervous system.

Sebaceous glands can help harvest hair follicle stem cells to regenerate skin and hair.

Hair follicle stem cells are a promising source for tissue repair and treating skin or hair diseases.

Hair follicle regeneration needs special conditions and young cells.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

Scientists created 3D hair-like structures that could help study hair growth and test treatments.

Advanced therapies like gene, cell, and tissue engineering show promise for hair regrowth in alopecia, but their safety and effectiveness need more verification.

Topical minoxidil is the best-supported treatment for female hair loss, but personalized plans are needed.

Mohs micrographic surgery is effective for early-stage non-melanoma skin cancers on the lips, with basal cell carcinoma more common on the upper cutaneous lip and squamous cell carcinoma more common on the lower vermilion lip.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

The flap assay grows the most natural hair but takes the longest, the chamber assay is hard work but gives dense, normal hair, and the patch assay is quick but creates poorly oriented hair with some issues.

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

A new model for hair regeneration in mice was created in 2015, which is faster and less invasive than the old method, producing normal hairs in about 21 days.

Tacrolimus causes fewer acute rejections than cyclosporin A in kidney transplants but doesn't necessarily improve kidney function after one year; cardiovascular risks and side effects vary between the two drugs.

Human hair follicles can regenerate after removal, but with low success rate.

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.

Permanent hair loss after a stem cell transplant can be a sign of chronic immune system attack on the scalp.

A man experienced skin death after a hair transplant, likely due to poor blood supply related to his smoking habit.

Cell transplantation faces challenges in genitourinary reconstruction, but alternative tissue sources and microencapsulation show promise.

Transplant patients often get skin problems, with treatments varying by condition.

A man developed autoimmune issues after a transplant, improved with treatment, but died from leukemia relapse.

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.

Platelet-Rich Fibrin (PRF) can speed up healing in chronic wounds, improve hair density, and act as a natural filler for skin rejuvenation, but its use in hair loss treatment needs more evaluation.

Surgical methods like suction blister grafting and split-thickness skin grafting are highly successful for vitiligo repigmentation, but choosing the right patients is crucial for success.

Transplanting skin cells is a safe, effective, and affordable treatment for vitiligo.

The study found unique skin changes in a rare type of alopecia linked to a skin condition called linear morphea.

Microencapsulation helps protect and track therapeutic cells, showing promise for treating various diseases, but more work is needed to improve the technology.

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.
