Gene Expression

Caption

MIT engineers developed a way to set gene expression levels at off, low, or high. Using skin cells, the researchers delivered a cocktail (labeled with a red fluorescent protein, top row) that boosts the conversion of skin cells into motor neurons. Via promoter editing, they show that higher levels of this cocktail increase the number of motor neurons (green). In the bottom row, the same cells are labeled with a green fluorescent protein that is generated after the cells convert to motor neurons.
