Cells in retina found to behave like soap bubbles
...-doctoral fellow at Northwestern, looked at normal retinal cells where four cells group together to form an aperture that is circular in shape. They found that they did so in exactly the same pattern as a group of four soap bubbles. Then, they varied the number of cells in each aperture and looked at how the...Retinal stem cells can regenerate after transplant
