In an exciting paper by from a group from Stanford, researcher Andrew Yoo and colleagues have demonstrated that fibroblasts can be transformed into neurons using RNAi to coax these skin cells into becoming functional neurons.
Different cell type (skin cells, neurons, osteoblasts, etc.) start out from less specialized cells, called stem cells. What a cell will become (its characteristics and functions) is also known as the cell’s “fate.” It may seem odd that seemingly simple skin cells can be transformed into cells that make up the thinking brain. However, all cells have a common set of DNA instructions, and it is More >
