    TLDR Advancements in creating skin grafts with biomaterials and stem cells are promising, but more research is needed for clinical application.
    The document from July 1, 2019, reviews the progress and challenges in skin tissue engineering, with a focus on creating functional skin grafts by combining biomaterials and stem cells. It outlines the complexity of replicating native skin due to its structure and cell-matrix interactions, and the need for 3D constructs that maintain cell functionality. The review discusses the importance of hypodermal engineering, pigmentation, and vasculature in wound healing, and compares different cell sources like embryonic stem cells, iPSCs, MSCs, and ADSCs. It emphasizes the role of biomaterials in scaffold fabrication, detailing the required characteristics for successful tissue repair and regeneration. The document also explores the use of nanotechnology in scaffold fabrication and targeted delivery of growth factors, and the potential of stem cell technology in promoting angiogenesis and tissue formation. It concludes that while advancements have been made, more work is needed to understand tissue differentiation in artificial systems and to scale findings to clinically relevant skin grafts.

      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
