Proteomics characterisation of induced pluripotent stem cells and cortical brain organoids.


ABSTRACT: A method was developed to reproducibly produce neural retina and cortical brain regions from confluent cultures of stem cells. The spontaneously generated cortical organoids were isolated and cultured in suspension conditions for maturation. Proteomic analysis of both the original induced pluripotent stem cells and the cortical organoids demonstrated the increased presence of synaptic components, indicating maturity.

Advances in the study of neurological conditions have been possible because of pluripotent stem cell technologies and organoids. Studies have described the generation of neural ectoderm-derived retinal and brain structures from pluripotent stem cells. However, the field is still troubled by technical challenges, including high culture costs and variability. Here, we describe a simple and economical protocol that reproducibly gives rise to the neural retina and cortical brain regions from conflue  ...[more]
