Chemical transdifferentiation: closer to regenerative medicine
null

Cell transdifferentiation, which directly switches one type of differentiated cells into another cell type, is more advantageous than cell reprogramming to generate pluripotent cells and differentiate them into functional cells. This process is crucial in regenerative medicine. However, the cell-converting strategies, which mainly depend on the virus-mediated expression of exogenous genes, have clinical safety concerns. Small molecules with compelling advantages are a potential alternative in manipulating cell fate conversion. In this review, we briefly retrospect the nature of cell transdifferentiation and summarize the current developments in the research of small molecules in promoting cell conversion. Particularly, we focus on the complete chemical compound-induced cell transdifferentiation, which is closer to the clinical translation in cell therapy. Despite these achievements, the mechanisms underpinning chemical transdifferentiation remain largely unknown. More importantly, identifying drugs that induce resident cell conversion in vivo to repair damaged tissue remains to be the end-goal in current regenerative medicine.

Therapeutic potential of stem cell in liver regeneration

Liver transplantation is the only life-saving procedure for patients with end-stage liver disease. However, its potential benefits are hampered by many disadvantages, such as the relative shortage of donors, operative risks, and high costs. These issues have prompted the search for new alternative therapies for irreversible liver disease. Stem cell therapy, with the ability for self-renewal and potential for multilineage differentiation, is a promising alternative approach. Several studies have demonstrated that transplantation of hepatic stem/progenitor cells or hepatocyte-like cells derived from multipotent stem cells leads to donor cell-mediated repopulation of the liver and improved survival rates in experimental models of liver disease. However, a registered clinical application based on stem cell technology will take at least an additional 5 to 10 years because of some limitations; e.g. the lack of suitable cell sources and risk of teratoma formation. This review summarizes the general understanding of the therapeutic potentials of stem cells in liver disease, including the sources, mechanisms, and delivery methods of hepatic stem cells in liver regeneration, and discusses some challenges for their therapeutic application.

Platelet-rich plasma: combinational treatment modalities for musculoskeletal conditions

Current research on common musculoskeletal problems, including osteoarticular conditions, tendinopathies, and muscle injuries, focuses on regenerative translational medicine. Platelet-rich plasma therapies have emerged as a potential approach to enhance tissue repair and regeneration. Platelet-rich plasma application aims to provide supraphysiological concentrations of platelets and optionally leukocytes at injured/pathological tissues mimicking the initial stages of healing. However, the efficacy of platelet-rich plasma is controversial in chronic diseases because patients’ outcomes show partial improvements. Platelet-rich plasma can be customized to specific conditions by selecting the most appropriate formulation and timing for application or by combining platelet-rich plasma with synergistic or complementary treatments. To achieve this goal, researchers should identify and enhance the main mechanisms of healing. In this review, the interactions between platelet-rich plasma and healing mechanisms were addressed and research opportunities for customized treatment modalities were outlined. The development of combinational platelet-rich plasma treatments that can be used safely and effectively to manipulate healing mechanisms would be valuable and would provide insights into the processes involved in physiological healing and pathological failure.
