| Outline of Final Research Achievements |
Adipocytes are critically involved in enhancing the clinical risk of metabolic syndrome. Adipocytes can arise from mesenchymal stem cells (MSCs) that can differentiation to many cell types such as adipocytes, bone, cartilage, tendon, muscle, skin, and nerves. Wnts are secreted signaling proteins that regulate differentiation into osteoblast of MSCs. On the other hand, peroxisome proliferator-activated receptor γ (PPARγ) is a critical factor for adipogenesis. PPARγ agonists are induces the differentiation into adipocyte of MSCs but Wnts are inhibit the adipocyte differentiation. Wnt proteins are comprised a large family of nineteen proteins and highly conserved in many species. To date major signaling branches downstream of the Fz receptor have been identified including a canonical or Wnt/β-catenin dependent pathway and the non-canonical or β-catenin-independent pathway. Here we show that role of the Wnt signaling in the differentiation mechanism from the MSC into adipocytes.
