Scientists here are one step closer to growing a human heart from stem cells.
The team from the Agency for Science, Technology and Research (A*Star) took a mouse's heart and removed its cells, leaving behind a scaffold.
They then implanted the scaffold with human stem cells - which can grow into different types of cells - and after 14 days the cells developed into heart cells.
The cell-laden scaffold was implanted back into the mouse, where blood vessels, necessary for the transport of nutrients and oxygen to the heart, developed.
