Hertz Fellow Luis Alvarez, the bioengineer leading manufacturing at United Therapeutics, wants to build you a new lung – but not one cell at a time. Traditional bioprinting, where cells are squeezed into place through a hollow needle is, he says, akin to “pushing water balloons through a straw.” It’s a constrained process that limits the resolution of the resulting tissue’s structure. Instead, Alvarez and United are focused on “recellularization,” where living cells are infused into a printed scaffold of structural collagen.
