At an early stage of development, the miniature organs grown from autistic patients» stem cells also showed
faster cell division rates than those grown from the cells of non-autistic relatives.
They showed that when these cells experience warmer temperatures and get more nutrients they can double or triple
their cell division rates, allowing them to potentially bloom into a large population fairly quickly at sea.
However, Dr Pullen and his team present evidence that plant growth is actually «sink - limited,» meaning that genetic regulation and
cell division rates have a much bigger role in controlling plant growth than previously thought: «We are proposing that plant growth is not physically limited by Net Primary Productivity (NPP) or the environment, but instead is limited genetically in response to these signals to ensure they do not become limiting.»
