Here, it is shown that it is possible to create in vitro,<\/em> in about 30 min, a tubular microenvironment with an elastic modulus and porosity consistent with human tissue that functionally mimicks a bona fide<\/em> capillary using \u201clive cell lithography\u201d(LCL) to control the type and position of cells on a composite hydrogel scaffold. Furthermore, it is established that these constructs support the forces associated with blood flow and produce nutrient gradients similar to those measured in vivo<\/em>. With LCL, capillaries can be constructed with single cell precision\u2014no other method for tissue engineering offers such precision. Since the time required for assembly scales with the number of cells, this method is likely to be adapted first to create minimal functional units of human tissue that constitute organs, consisting of a heterogeneous population of 100\u20131000 cells, organized hierarchically to express a predictable function.<\/p>\n\n\n\n
