| Outline of Final Research Achievements |
Brown adipocytes maintain body temperature by burning lipid, which can prevent obese and diabetes by enhancing energy expenditure. Brown adipocytes are differentiated from induced pluripotent stem cells (iPSCs) and directly converted from fibroblasts by virus vector-mediated expression of a specific set of transcription factors. In order to provide a safer approach to generate brown adipocytes, we developed chemical compound-based direct conversion from human dermal fibroblasts into brown adipocytes without any genetic manipulation. The chemical compound-induced brown adipocytes (ciBAs) exhibit expression of human brown adipocyte-specific genes including Ucp1, activation of thermogenic gene expression through adrenergic receptor, and increased oxygen consumption rates. Our findings might provide an easily accessible approach for generating human brown adipocytes from fibroblasts and offer therapeutic potential for the management of obesity, diabetes, and related metabolic disorders.
