Scientists developed a method to grow human fetal skin and digits in a lab for 3-4 weeks, which could help study skin features and understand genetic interactions in tissue formation.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Alopecia areata is likely an autoimmune disease with unclear triggers, involving various immune cells and molecules, and currently has no cure.

New effective scar treatments are urgently needed due to the current options' limited success.

Low doses of some substances can be beneficial, while high doses can be harmful or toxic.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

A new hydrogel with stem cells from human umbilical cords improves skin wound healing and reduces inflammation.

Some drugs, especially biologics, can cause skin reactions that look like other skin diseases, and stopping the drug usually helps clear up these reactions.

Some growth factors, while important for normal body functions, can cause diseases when not regulated properly.

Botulinum toxin type A significantly reduces scalp psoriasis severity compared to placebo.

Key genes crucial for sheep hair follicle development were identified, aiding fine wool breeding and human hair loss research.

Platelet-rich plasma (PRP) is effective in treating various skin conditions and improving hair density, thickness, and patient satisfaction, with lower relapse rates for Alopecia Areata.

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

The combined treatment for hair loss is effective, easy to use, and has mild side effects.

The best method for urethral reconstruction is using hypoxia-preconditioned stem cells with autologous cells on a vascularized synthetic scaffold.

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.

HSP90 and lamin A/C are crucial for hair growth and could be targets for treating hair loss.

Newly divided skin cells quickly move to join skin structures due to tissue tension and specific signals.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Moracin M boosts hair growth by activating key pathways and promoting cell growth.

Skin cell strength decreases significantly as we age.
