Wound healing involves three phases and various cells and factors, with scars typically forming in adults. Chronic wounds can occur due to various issues, and abnormal scarring can lead to hypertrophic or keloid scars. Emerging research areas include the role of proteins, microRNAs, macrophage manipulation, and stem cell treatment.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

Stretching skin increases a certain protein that attracts stem cells, helping skin regeneration.
