The disclosure relates to novel compositions comprising 1) conditioned media, 2) combinations of secreted biomolecules/organic molecules, and/or 3) secreted extracellular vesicles/exosomes collected from differentiated epithelial cell culture, as well as methods of making and using such compositions.

Disclosed herein are synthetic leathers, artificial epidermal layers, artificial dermal layers, layered structures, products produced therefrom and methods of producing the same.

The present invention relates to a method of cultivating an epithelial stem/progenitor cell population of the amniotic membrane of umbilical cord, the epithelial stem/progenitor cell population having the capacity to differentiate in multiple cell types.

The technology relates in part to methods and compositions for ex vivo proliferation and expansion of epithelial cells.

A skin sample culture apparatus which has a base frame, with a skin sample receiving surface upon which at least part of the skin sample may be placed and which extends across an area defined by the shape of the frame. A securing member which is releasably connectable to the base frame and a grip which holds the skin sample under tension. The apparatus may include a tensioner to hold the sample under tension and means for introducing a fluid to the upper or lower surface of the sample.

The invention relates to a method for manufacturing a bio-ink by additive deposition, which comprises supplying: a first solution including between 5 and 40 wt. % gelatin; a second solution including between 15 and 35.wt. % alginate; a third solution including between 1 and 15 wt. % fibrinogen, and optionally living cells in suspension; and creating a mixture including: around 35 to 65 vol. % of the first solution; around 15 to 35 vol. % of the second solution; and around 15 to 35 vol. % of the third solution, said proportions being selected so that they add up to 100%. Said bio-ink allows the additive deposition of objects that can be polymerised by means of a solution including calcium ions and thrombin. Said objects can be incubated and can be used as a substitute for body tissue, for example (with added fibroblasts) as skin substitute.

A process and system provides for atraumatic preparation of morselized Tissue Particles (TP)s, such as Full Thickness Skin Graft Particles (FTSGPs), cartilage particles and other organ tissue particles, in a liquid medium. The resultant tissue product may be a suspension of Tissue Particles in an aqueous solution and containing highly viable cells and may be rapidly prepared at bedside or in the operating room and conveniently delivered to a patient through a syringe or similar applicator. The morselized Tissues Particles may be used for surgical applications including wound healing, cosmetic surgery, and orthopedic cartilage repairs.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding a polypeptide; viruses comprising the recombinant nucleic acids; compositions comprising the recombinant nucleic acids and/or viruses; methods of their use; and articles of manufacture or kits thereof.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding a Serine Protease Inhibitor Kazal-type (SPINK) polypeptide (e.g., a SPINK5 polypeptide); viruses comprising the recombinant nucleic acids; compositions and formulations comprising the recombinant nucleic acids and/or viruses; methods of their use (e.g., for the treatment of Netherton Syndrome); and articles of manufacture or kits thereof.

The invention relates to the use of matrix cells for obtaining a micro hair follicle and to the use thereof for evaluating the effect of cosmetic, pharmaceutical or dermatological products and also for the prophylactic or therapeutic treatment of a state of reduced pilosity.
