The development of a technique to induce the transformation of somatic cells to a pluripotent state via the ectopic expression of defined transcription factors was a transformational event in the field of regenerative medicine. The development of this technique also impacted ophthalmology, as patient-specific induced pluripotent stemcells (iPSCs) may be(More)
Cancer stem cells (CSCs) play an important role in drug resistance of tumor and are responsible for high recurrence rates. Agents that can suppress the proliferation and differentiation of CSCs would provide new opportunity to fight against tumor recurrence. In this study, we developed a new strategy to enrich CSCs in human osteosarcoma cell line hMG63.(More)
PURPOSE Retinal microglia can be activated and recruited by chemokines and play a protective role in early retinal degeneration. CC-chemokine ligand 2 (CCL2) and its receptor, CC-chemokine receptor 2 (CCR2), have been implicated as key mediators for the trafficking and accumulation of microglial cells in lesioned tissue. The current study investigates(More)
Human amniotic epithelial cells were isolated from a piece of fresh amnion. Using immunocytochemical methods, we investigated the expression of neuronal phenotypes (microtubule-associated protein-2, glial fibrillary acidic protein and nestin) in human amniotic epithelial cells. The conditioned medium of human amniotic epithelial cells promoted the growth(More)
Retinal microglia play an important role as resident immunocompetent and phagocytic cells in the event of injury and disease. Retinal microglia and microglia precursor transplantation show a rescue effect in ischemic retina and retinal degeneration. However, studies of retinal microglia have been hampered by the difficulty of obtaining sufficient numbers of(More)
