Scar is an inevitable consequence of full-thickness skin injury. Hypertrophic scar and keloid are caused by abnormal wound healing. Mechanical factors play an important role in scar formation. An extensive literature review on mechanobiology of scar and wound healing, as well as a summary of the mechanobiological factors of scar formation and treatments, and mechanical model of scar were conducted, with guiding future development in this research field.

Adipose-derived mesenchymal stem cells (ASCs) are pluripotent adult mesenchymal stem cells that are expected to be ideal seed cells for bone tissue engineering(BTE) due to their biosecurity, abundance, and easy access. However, in comparison with bone marrow mesenchymal stem cells, ASCs possess a relatively limited osteogenic capacity and often require further induction. Advances on strategies for promoting osteogenic differentiation of ASCs are reviewed from following aspects: optimization of scaffolds, addition of bioactive factors or drugs, non-coding RNA regulation, and physical stimulation, so as to provide references for the use of ASCs in BTE.
