Although we successfully constructed contractile tissues using these hiPSCs in a previous study, further improvements are required because of their weak contractile force and inefficient screening capabilities. In this study, we aimed to construct iPSC-derived muscle tissues with high contractile force using a 96-well scale microdevice that we had previously developed. To increase the contractile force, we optimized the time of supplementation of the transforming growth factor-β (TGF-β) inhibitor, SB431542 (SB), to identify culture conditions that enhance contractile force. The maximum contractile force with addition of SB was approximately five times greater than that without SB (58.45 ± 20.14 μN with SB compared to 11.64 ± 4.86 μN without SB). Various analyses, including immunostaining, transmission electron microscopy, gene expression analysis, and proteomics, revealed enhanced myotube differentiation and muscle tissue maturation in the presence of SB. Experiments using inhibitors indicated that TGFβ1, not myostatin, is partially involved in these effects. Furthermore, we confirmed that tissues constructed from iPSCs derived from patients with Duchenne muscular dystrophy also showed improved contractility following addition of SB.

Therefore, technical improvements that prevent cell death in the core region of cell aggregates are desired for the development of large, thick tissues. We focused on the anti-glycolytic effects of resveratrol (RSV), a polyphenol known as a caloric restriction mimetic, and investigated its cytoprotective effects under glucose-deprived conditions in two-dimensional (2D) and 3D-cell culture systems using rat chondrocytes. In 2D culture, the low-glucose (LG, 0.5 mg/mL) condition caused time- and dose-dependent cell death in chondrocytes, whereas co-treatment with 50 μM RSV significantly restored cell viability under glucose deprivation. In RSV-treated cells, the expression levels of glycolytic genes (GLUT1, PKM, and LDHA) and glucose uptake were significantly downregulated, and phospho-AMPK levels were upregulated, indicating energy stress. RSV treatment restored the expression of extracellular matrix genes (COL1A1 and COL2A1), which were downregulated under the LG condition, and augmented the pro-chondrogenic effect of TGF-β1 and ascorbic acid. In a 3D-culture model, spheroids constructed with RSV-pretreated chondrocytes had a more viable core region than dimethyl-sulfoxide-treated control spheroids. TGF-β-induced cartilage maturation led these spheroids to develop larger and more viable tissues than control spheroids. These results suggested that glycolytic inhibition by RSV decreased chondrocyte glucose usage, thereby preventing cell death caused by glucose deprivation.
