WebWhether ferric ions promote neuronal differentiation and subsequently promote motor neuron lineage has never been considered. Here, we demonstrate that elevated iron concentration can drastically accelerate the differentiation of human embryonic stem cells (hESCs) toward motor neuron lineage potentially via a transferrin mediated pathway. WebUltimately, both the gray and white matter become involved, with corresponding loss of differentiation on CT. There is overall restriction of diffusion of water molecules across the cell membrane and within the cytoplasm resulting in regional high signal on DWI and low signal on ADC images.
