Alzheimer's disease (AD) is a leading cause of age-related dementia that is characterized by an extensive loss of neurons and synaptic transmission. The pathological hallmarks of AD are neurofibrillary tangles and deposition of β-amyloid (Aβ) plaques. Previous research has investigated how Aβ fragments disrupt synaptic mechanisms in the vulnerable regions of the brain. There is a tremendous potential for stem cell technology to extend upon this research, not only in terms of developing therapeutic applications, but also in modeling AD. Indeed, the advent of induced pluripotent stem cell technology has opened up exciting new avenues for generating patient and disease-specific cell lines from somatic cells that may be used to model AD. Amyloid precursor protein (APP) is a key protein in neuronal development and this article reviews the role of APP in AD. Stem cell technology offers the opportunity to make use of APP in the directed differentiation of induced pluripotent stem cells into functional neurons, a process that may help generate a model of AD and thereby facilitate an understanding of the mechanisms underlying this disease.

The lack of in vivo accurate human liver models hinders the investigation of liver-related diseases, injuries, and drug-related toxicity, posing challenges for both basic research and clinical applications. Traditional cellular and animal models, while widely used, have significant limitations in replicating the liver's complex responses to various stressors. Liver organoids derived from human pluripotent stem cells, adult stem cells primary cells, or tissues can mimic diverse liver cell types, major physiological functions, and architectural features.

A 3-dimensional (3D) cell culture is now being actively pursued to accomplish the in vivo-like cellular morphology and biological functions in cell culture. We recently obtained nano-fibrillated bacterial cellulose (NFBC). In this study, we developed a novel NFBC-based 3D cell-culture system, the OnGel method, and the Suspension method.

Fabry disease (FD) is a systemic disease in which globotriaosylceramide and other naturally occurring glycosphingolipid accumulate in various tissues throughout the body due to mutation of α-galactosidase A (GLA). These induced pluripotent stem cells (iPSCs) were generated from a 10-year-old male patient's urine carrying the GLA c.1080_1082del Fabry disease mutation.

Hematopoietic stem cells (HSCs) generate blood and immune cells. Here, we present a protocol to differentiate human pluripotent stem cells (hPSCs) into hematopoietic progenitors that express the signature HSC transcription factors HLF, HOXA5, HOXA7, HOXA9, and HOXA10. hPSCs are dissociated, seeded, and then sequentially differentiated into posterior primitive streak, lateral mesoderm, artery endothelium, hemogenic endothelium, and hematopoietic progenitors through the sequential addition of defined, serum-free media.
