MIMICKING the environment experienced by cells in the windpipe is enough to transform stem cells into a range of different lung cells. Such “physical” techniques could be used to create specialised tissues when growth factors alone aren’t enough. Lindsey Van Haute of the Free University of Brussels (VUB) in Belgium and colleagues spread human embryonic stem cells onto a porous membrane. The cells were fed from beneath by nutrients and from above by a fluid that encouraged them to multiply. Removing two chemicals from the growth fluid kick-started differentiation. Four days later, the team removed the fluid covering the cells,
