Motor Neurons Phenotypic Screening Assay
Motor neurons are a specialized group of neurons responsible for transmitting signals from the central nervous system (CNS) to muscles, allowing for voluntary movement. Dysfunction of motor neurons can lead to various neurological disorders, including Amyotrophic Lateral Sclerosis (ALS) and Spinal Muscular Atrophy (SMA). The study of motor neurons and their associated diseases has been the focus of intense research in recent years. Creative Biolabs has developed a cutting-edge Motor Neurons Phenotypic Screening Assay, which can be used for in vitro disease modeling and drug screening.
Culture of Human iPSC-derived Motor Neurons
Creative Biolabs has established a robust protocol for the culture of human induced pluripotent stem cell (iPSC)-derived motor neurons. These motor neurons are derived from patient-specific iPSCs, allowing for the study of disease-specific phenotypes. The protocol involves the differentiation of iPSCs into motor neurons using a combination of growth factors and small molecules.

Characterization of Human iPSC-derived Motor Neurons
Creative Biolabs employs a range of techniques to characterize human iPSC-derived motor neurons. Immunostaining is used to confirm the expression of motor neuron-specific markers, including FoxP1, ChAT, and MAP2. Electrophysiological recordings are used to confirm the functionality of the motor neurons. Additionally, gene expression analysis can be used to assess the expression of genes associated with motor neuron development and function.

ALS/SMA in vitro Disease Model
ALS and SMA are neurodegenerative diseases characterized by the progressive loss of motor neurons, leading to muscle weakness, paralysis, and ultimately death. Creative Biolabs has developed an in vitro disease model for ALS/SMA using human iPSC-derived motor neurons. This model allows for the study of disease-specific phenotypes and the screening of potential therapeutic compounds. The ALS/SMA in vitro disease model is characterized by the progressive loss of motor neurons, which can be quantified using immunostaining and electrophysiological recordings.
