For the first time, scientists have added microscopic tracking devices into the interior of cells, giving a peek into how development starts.
For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development. This work on one-cell embryos is set to shift our understanding of the mechanisms that underpin cellular behavior in general, and may ultimately provide insights into what goes wrong in aging and disease. The research, led by Professor Tony Perry from the Department of Biology and Biochemistry at the University of Bath, involved injecting a silicon-based nanodevice together with sperm into the egg cell of a mouse. The result was a healthy, fertilized egg containing a tracking device. The tiny devices are a little like spiders, complete with eight highly flexible ‘legs’.
