A team of researchers affiliated with several institutions in South Korea and one in Switzerland has demonstrated that it is possible to use magnetically actuated microrobots to deliver stem cells to targeted tissue. In their ...
A team of researchers working at the University of St Andrews in Scotland has found a way to place a laser inside a living human cell. In their paper published in the journal Nano Letters, the team describes their technique ...
Micropores in fabricated tissues such as bone and cartilage allow nutrient and oxygen diffusion into the core, and this novel approach may eventually allow lab-grown tissue to contain blood vessels, according to a team of ...
