A method of manufacturing a multilayered cell sheet of neural crest stem cells (NCSCs), includes: (1) isolating and culturing NCSCs from peripheral nerves; (2) embedding the cultured NCSCs in a hydrogel; (3) culturing the hydrogel comprising the NCSCs embedded therein under stressed culture conditions in which a physical support is applied; and (4) culturing the resulting hydrogel of step (3) under non-stressed culture conditions in which a physical support is removed.

The present invention relates to a composition for stimulating hair growth or preventing hair loss, which contains a conditioned medium or extract of neural stem cells (NSCs) isolated from the ventricular zone of the human brain, and to a preparation method thereof. The conditioned medium or extract of neural stem cells according to the present invention contains various growth factors and cytokines, and thus has an excellent effect on the stimulation of hair growth. Thus, it is useful for hair growth stimulation and hair loss prevention.

A method for differentiation of neural stem cells, neurons and GABAergic neurons from mesenchymal stem cells includes culturing the mesenchymal stem cells in a medium containing SB431542, Noggin and LDN193189. By this method, the mesenchymal stem cells are differentiated into neural stem cells, neurons and GABAergic neurons at a high transformation rate without gene manipulation.

The present invention relates to a method of producing organoids, said method comprising or consisting of: (a) seeding a plurality of tissue-specific precursor cells into a container; (b) allowing to occur (i) aggregation of said cells; and (ii) maturation of the aggregate formed in (i) into a single organoid; wherein said method does not comprise embedding of said cells or said aggregates into a gel.

Described herein are chemically defined, adherent culture protocols for generating functional motor neurons characteristic of diverse hindbrain and spinal cord regions, with high efficiency.

A bacteriophage structure, a method of making the structure, and uses of the structure are described. The structure is a substrate with a surface having an ordered arrangement of parallel microridges thereon. Each microridge is composed of a plurality of nanoridges and has a longitudinal axis. Each nanoridge contains a bundle of phage nano fibers having longitudinal axes. The phage nanofibers in each nanoridge bundle are arranged in a substantially smectic alignment. The longitudinal axis of each microridge is perpendicular to the longitudinal axes of the phage nanofibers which make up the nanoridges of the microridge. The structure may be used as a growth surface for inducing differentiation of stem cells such as neural progenitor cells.

The present invention provides a method for generation of a cell composition of mesencephalic dopaminergic progenitor cells from a starting cell composition comprising pluripotent and/or multipotent stem cells, the method comprising the steps of a) differentiating said pluripotent and/or multipotent stem cells into mesencephalic dopaminergic progenitor cells, thereby generating a cell population comprising mesencephalic dopaminergic progenitor cells and other cells, b) dissociating the differentiated cells of step a) into a single cell suspension, and c) enriching said mesencephalic dopaminergic progenitor cells by using an antigen binding molecule specific for the CD47 antigen for positive selection of said mesencephalic dopaminergic progenitor cells in said single cell suspension. Said method may be performed in a closed cell sample processing system and may be performed in an automated manner.

The invention relates generally to methods of treating spasticity, rigidity, or muscular hyperactivity conditions by introducing a portion of an expanded population of neural stem cells into an area of a recipient spinal cord.

[Problem] To provide a cell culture substrate, and a cell culturing method using the substrate and a method for inducing differentiation of pluripotent stem cells using the substrate, which allow culturing of pluripotent stem cells and allow differentiation of pluripotent stem cells into a specified cell species, particularly neural and neural progenitor cells, at a high purity. [Means for Solution] A cell culture substrate, characterized in that, onto the surface, one or more selected from the group consisting of N-cadherin, a fusion protein comprising an entire or partial region of N-cadherin, and a fusion protein comprising an entire or partial region of a protein homologous to N-cadherin are immobilized or coated.
