Tumor cells often appear in a deviant differentiated stage, and dedifferentiation is a hallmark of malignancy; however, the causative mechanism of the global changes in dedifferentiation is not understood. The GATA transcription factors function in cell lineage specification during embryonic development and organ formation. The transcriptional targets of the GATA factors in early embryonic deve...
Loss of hyaline chondrocyte phenotype during the monolayer culture in vitro is a major obstacle for cell-based articular cartilage repair. Increasing evidence implicates an important role of the epigenetic regulation in maintaining the chondrocyte phenotype. DNA methylation, histone modifications and microRNAs have all been shown to contribute to chondrocyte dedifferentiation and hypertrophy. M...
Analyses of mature adipocytes have shown that they possess a reprogramming ability in vitro, which is associated with dedifferentiation. The subsequent dedifferentiated fat cells (DFAT cells) are multipotent and can differentiate into adipocytes and other cell types as well. Mature adipocytes can be easily obtained by biopsy, and the cloned progeny cells are homogeneous in vitro. Therefore, DFA...
Schwann cells (SCs) in the peripheral nerves myelinate axons during postnatal development to allow saltatory conduction of nerve impulses. Well-organized structures of myelin sheathes are maintained throughout life unless nerves are insulted. After peripheral nerve injury, unidentified signals from injured nerves drive SC dedifferentiation into an immature state. Dedifferentiated SCs participat...
Introduction Articular cartilage is a highly specialized tissue that is vulnerable to injury and disease and has a limited capacity for self-regeneration. The autologous chondrocyte transplantation technique has not been successful because of rapid dedifferentiation of chondrocytes in monolayer culture, producing fibroblast-specific markers (mainly collagen I) rather than a cartilage-specific m...
