The present invention relates to compositions and methods utilizing hair follicle derived Non-Bulbar Dermal Sheath cells for use in the treatment of skin.

A method or apparatus for creating a three-dimensional tissue construct of a desired shape for repair or replacement of a portion of an organism. The method may comprise injecting at least one biomaterial in a three-dimensional pattern into a first material such that the at least one biomaterial is held in the desired shape of the tissue construct by the first material. The apparatus may comprise an injector configured to inject at least one biomaterial in a three-dimensional pattern into a first material such that the at least one biomaterial is held in the desired shape of the tissue construct by the first material. The first material may comprise a yield stress material, which may be a material exhibiting Herschel-Bulkley behavior. The tissue construct may have a smallest feature size of ten micrometers or less.

A 3D decellularized bone scaffold seeded with cancer cells, such as prostate cancer cells or Ewing's sarcoma is provided. The three-dimensional includes Ewing's sarcoma (ES) tumor cells; and an engineered human bone scaffold. The engineered human bone scaffold further includes osteoblasts that secrete substance of the human bone, and osteoclasts that absorb bone tissue during growth and healing. The engineered human bone scaffold includes the tissue engineered three-dimensional model which recapitulates the osteolytic process. The engineered human bone scaffold is engineered by co-culturing of osteoblasts and osteoclasts. The osteoblast is produced by cell differentiation process from mesenchymal stem cells. The osteoclast is produced by cell differentiation from human monocytes, wherein the human monocytes are isolated from buffy coats. The scaffold can be used with cancer cell lines to identify therapeutic targets to slow, stop, and reverse tumor growth and progression as well as to predict the efficacy of potential therapeutics.

Fully dissolved, aqueous solutions of polycationic macromolecules and polyanionic macromolecules with a cell suspension are mixed to form a three dimensional hydrogel, useful for clinical, diagnostic, and therapeutic applications.

A carrier for cell culturing that contains a multiwell plate, where at least one of the wells of the multiwell plate has a porous substrate having the porosity of 90% and adapted for cell culturing, and the porous substrate adheres to the surface of the well. A method for preparation of the carrier for cell culturing is also provided.

The present invention relates to a composition comprising mesenchymal stem cell-hydrogel-biodegradable support or mesenchymal stem cell-hydrogel-undegradable support, a sheet comprising the composition and a method for the preparation thereof. By using the sheet comprising the adipose-derived mesenchymal stem cell-hydrogel biodegradable or undegradable support, stem cells of high activity may be applied directly to the wound without isolation process using protease. The sheet has extracellular matrices such as collagen, laminin, fibronectin and elastin secreted by stem cells in the culture stage and included completely in the hydrogel, and therefore it has superior skin regeneration and wound healing effects compared with conventional pharmaceutical preparations and shortens therapeutic period.

Improved hybrid neurovascular spheroids and methods for making the same are provided. In some embodiments of a method for making a hybrid neurovascular spheroid, the method includes i) propagating cortical cells to form a cortical spheroid; ii) propagating endothelial cells to form an endothelial spheroid; iii) propagating mesenchymal stem cells to form a mesenchymal cell culture; and iv) combining the cortical spheroid, endothelial spheroid, and mesenchymal spheroid under conditions to form the hybrid neurovascular spheroid.

A liver-mimetic device and method include a 3D polymer scaffold having a matrix of liver-like lobules with hepatic-functioning particles encapsulated within the lobules. In some embodiments, each liver-like lobule is hexagonal in structure and the matrix is in a honeycomb arrangement. In some embodiments, the hepatic-functioning particles are hepatic progenitor cells. In other embodiments, the hepatic-functioning particles are polymer nanoparticles adapted to capture pore-forming toxins.

A therapeutic agent for intervertebral disc degeneration that contains LASCol obtained by enzymatically cleaving a terminus of collagen.

Provided are skin constructs and methods of making and using the same, such as for wound treatment and/or compound testing, including compound testing for efficacy, toxicity, immune response, penetration, irritation and/or metabolism testing of drug candidates or compositions such as cosmetics.
