Further, neural plate tissue obtained using methods of the present inventions are contemplated for use in co-cultures with other tissues as inducers for shifting differentiation pathways, i.e. patterning.

An object of the present invention is to provide an agent effective for the treatment and / or prevention of motor neuron disease such as amyotrophic lateral sclerosis (ALS). The present invention provides a therapeutic and / or preventive agent for motor neuron disease comprising the following oligopeptide shown in any of (a) to (c) or a pharmaceutically acceptable salt thereof as an active ingredient: (a) an oligopeptide consisting of the amino acid sequence represented by Ser-Ala-Leu-Leu-Arg-Ser-Ile-Pro-Ala (SEQ ID NO: 1); (b) an oligopeptide consisting of an amino acid sequence having a deletion, substitution, insertion, or addition of one or several amino acids in Ser-Ala-Leu-Leu-Arg-Ser-Ile-Pro-Ala (SEQ ID NO: 1), and having an activity that inhibits neuronal cell death caused by a mutant superoxide dismutase-1 gene; and (c) a modified oligopeptide from the oligopeptide (a) or (b).

The invention discloses a human motor neuron gene copy number relative quantitative detection method and a detection kit. The kit provided by the invention contains a single-stranded DNA group A for specifically detecting the seventh exon of the SMN gene and / or a single-stranded DNA group B for specifically detecting the eighth exon of the SMN gene, and each single-stranded DNA group consists of acommon primer and two probes for respectively detecting the SMN1 gene and the SMN2 gene. The kit is high in accuracy and good in repeatability. The method has important significance for rapidly screening SMN1 gene and SMN2 copy number and reducing birth rate of SMA children patients.

This document relates to methods and materials for assessing and / or treating a mammal (e.g., a human) having, or at risk of developing, a spinal condition (e.g., spinal muscular atrophy (SMA)). In some cases, a mammal can be identified as having, or as being likely to develop, a spinal condition (e.g., SMA), and, optionally, can be treated. For example, a mammal can be identified as having, or as being likely to develop, a spinal condition (e.g., SMA), based, at least in part, on the modification of nucleic acid that can encode a survival motor neuron (SMN) polypeptide (e.g., homozygous deletion of exon 7 of SMN1 nucleic acid encoding a SMN polypeptide and the genomic copy number of SMN2 nucleic acid encoding a SMN polypeptide) in a sample from a mammal and, optionally, can be treated.

The present invention includes assays and kits for detecting the assembly of an RNA binding protein-RNA complex and for detecting the activity of an RNA binding protein.

Type 2 diabetes (T2D) is a clinical syndrome caused by insufficient insulin secretion for insulin requirements. described herein are compositions and methods for microphysiological MPS models of disease (MODs) for diabetes. These platforms allow one to compare the effect of chronic β-cell stimulation in the presence and absence of patient specific immune cells in IPSC-derived islets from each group. Additionally, one can reproduce the T2D β-cell phenotype, using islets-on-chips will also be exposed to gluco-lipotoxicity. Likewise, skeletal muscle-on-chips are exposed to patient specific activated immune cells, variable motor neuron innervation and lipids characteristic of T2D.

Described herein is the discovery that neither the nuclear localization signal (NLS) nor the prion-like domain (PLD) of TDP-43 is necessary for embryonic stem cell culture and differentiation into motor neurons in vitro. The ability of ES cells to express these TDP-43 mutants and differentiate into motor neurons that exhibit an ALS-like phenotype whereby the TDP-43 mutants redistribute to and aggregate in the cytoplasm and fail to regulate cryptic exon splicing allows these cells to act as a model of TDP-43 proteinopathy for the testing of candidate therapeutic agents that may resolve such proteinopathy. Additionally, these ES cells may be used to successfully generate non-human animals, e.g., mice, that also exhibit hallmark symptoms of ALS and that may be used in testing candidate agents useful in treating TDP-43 proteinopathies.
