By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

The Notch pathway is a contact-dependent signaling pathway that controls cell-fate decisions, differentiation, proliferation, and tissue patterning through interactions between membrane-bound Notch receptors and membrane-bound ligands on neighboring cells. Canonical Notch signaling is activated when ligand engagement triggers proteolytic release of the Notch intracellular domain, which enters the nucleus and regulates transcription together with DNA-binding transcriptional complexes. In the canonical mechanism, ligand-dependent Notch activation leads to release of the intracellular Notch domain, and presenilin-dependent γ-secretase activity is required for production of the active intracellular signaling fragment. The released intracellular domain functions as a nuclear signal that converts Notch receptor activation at the membrane into transcriptional regulation of target programs such as HES/HEY-family genes and other context-dependent downstream targets. The literature links Notch p

This protocol maintains and expands human pluripotent stem cells under feeder-free, chemically defined conditions using E8 medium and vitronectin-coated culture surfaces; the readout is sustained adherent colony growth with undifferentiated morphology and retained pluripotency-marker expression during serial passaging. E8-based hPSC culture relies on defined soluble factors and matrix-dependent adhesion rather than feeder cells; vitronectin supports hPSC attachment through integrin-mediated interactions, and EDTA passaging dissociates colonies as small aggregates without enzymatic digestion, centrifugation, or routine ROCK-inhibitor treatment.

Alzheimer’s Disease (AD) is a neurodegenerative disorder characterized by a progressive decline in cognitive functions and loss of specific types of neurons and synapses. Alzheimer's symptoms can be simulated in mice by injecting drugs (such as Aβ) or genetically modified.
