Abstract: Methods for using compositions comprising a Granzyme B inhibitor and a pharmaceutically acceptable carrier for treating and/or preventing blistering and/or peeling of a skin of a subject are provided. Also provided are methods for using the compositions to improve the healing of a blistered or area of peeled skin of a subject. The compositions can be formulated for oral administration, nasal administration, topical administration, subcorneal administration, intra-epidermal administration, sub-epidermal administration, or for administration by injection.

Abstract: A print head, system and method for producing hollow fiber structures, for example three-dimensional biological structures comprising living cells, includes a dispensing channel, a core channel converging with the proximal end of the dispensing channel, a first shell channel converging with the core channel and the dispensing channel at a focusing intersection or chamber, and a sheath flow channel converging with the dispensing channel at a sheath flow intersection or chamber located between the focusing intersection or chamber and the distal end of the dispensing channel. The diameter of the dispensing channel increases from a first diameter to a second diameter at the sheath flow intersection or chamber, and the core channel has a third diameter less than the first and second diameters. The sheath flow channel includes sheath flow sub-channels and the focusing chamber has a conical frustum shape.
