Direct Reprogramming refers to the reprogramming of one cell into another. And the tech is developed for the studies of neuron diseases. With it, Human Brain Microvascular Endothelial Cells (http://www.creative-bioarray.com/Human-Brain-Microvascular-Endothelial-Cells-CSC-C1503-item-39320.htm) may be programmed and studied. Then when the tech gets into a mature state, it's possible for it to be applied for primary and tumor cells like Fibroblasts (http://www.creative-bioarray.com/celltype/fibroblasts-1.htm).
