A method for making a culture medium for culturing neural cells is provided. An original carbon nanotube structure is provided. The original carbon nanotube structure includes a drawn carbon nanotube film including a number of carbon nanotubes joined end to end by van der Waals force. The carbon nanotubes are substantially oriented along the same direction. A carbon nanotube structure including a number of carbon nanotube wires spaced from each other is formed by treating the original carbon nanotube structure. The carbon nanotube structure is fixed on a substrate.

Aspects of the invention are directed to mineral-based nanoparticles comprising silicate nanoparticles that induce human mesenchymal stem cells (hMSCs) into a cartilage-lineage through the upregulation of cartilage-specific genes resulting in the transformation of the cell phenotype into that of a chondrocyte, i.e., a cartilage producing cell. The silicate nanoparticles are synthesized through a process where the precipitate of sodium silicate is mixed with one or more elements and compounds and milled into nanoparticles.

Provided is a three-dimensional culture (10) of immortalized skin cells (2), comprising a plate-like substrate (1) and a culture layered product of immortalized skin cells adhering to the surface of the plate-like substrate, in which the superficial layer (3) of the culture layered product is composed of a stratum corneum. The three-dimensional culture can be produced as follows: immortalized skin cells are seeded on a top surface of a culture medium-impregnated plate-like substrate, and three-dimensional culture is performed while applying stress on a superficial layer of an immortalized skin cell layer formed by layering of the immortalized skin cells. The three-dimensional culture can be used to evaluate the sensitization of a test substance.
