3T3-L1 preadipocyte-to-adipocyte differentiation
3T3-L1 preadipocytes are induced to differentiate after growth arrest using adipogenic media containing insulin, dexamethasone, and IBMX; differentiation is assessed by lipid-droplet accumulation, triglyceride increase, Oil Red O staining, and adipocyte-marker induction such as PPARγ and C/EBPα.

Autophagy
Autophagy is a process in which eukaryotic cells use lysosomes to degrade their own cytoplasmic proteins and damaged organelles under the regulation of autophagy related gene (Atg). Microtubule-associated proteins light chain 3 (LC3) is recognized as autophagy marker, which transfers from cytoplasmic LC3 (LC3-I) to membrane type (LC3-II). LC3-II/I ratio could be detected by Western Blot and fluorescence microscopy.

Research Protocol for Inflammation-related Diseases
The NLRP3 inflammasome is a cytosolic innate immune signaling platform that integrates priming signals and danger-signal activation to promote caspase-1 activation, maturation of IL-1β and IL-18, and gasdermin D-mediated pyroptotic cell death. The core experimental logic is to determine whether inflammatory disease phenotypes are driven by increased NLRP3 expression, ASC-containing inflammasome assembly, caspase-1 cleavage, GSDMD cleavage, and extracellular release of IL-1β/IL-18 rather than by nonspecific cell injury alone. The pathway is strongly linked to inflammation-related disease phenotypes because monosodium urate crystals activate NALP3/NLRP3 inflammasome signaling in gout-like crystal inflammation, cholesterol crystals activate NLRP3 inflammasomes in atherogenesis models, and DSS-induced intestinal inflammation has been reported to involve NLRP3 inflammasome activity. However, experimental colitis studies also show context-dependent protective effects of NLRP3 inflammasome co

Lysosome and acidic-vesicle live-cell staining
Lysosome and acidic-vesicle live-cell staining detects acidic intracellular compartments by using membrane-permeant acidotropic probes that accumulate in low-pH vesicles, including lysosomes, late endosomes, autolysosomes, and acidic phagosomes. LysoTracker staining is commonly used as an intensity-based readout of acidic lysosomal compartment abundance or enlargement, while acridine orange produces green fluorescence in less concentrated compartments and red fluorescence after concentration-dependent accumulation in acidic vesicular organelles. Loss or reduction of acridine-orange red signal can be used as a readout of lysosomal membrane permeabilization or reduced acidic-vesicle integrity. This protocol is designed for live cultured cells and can be adapted for fluorescence microscopy, high-content imaging, plate-reader readout, or flow cytometry when the selected literature supports the readout. Because these dyes report acidotropic accumulation rather than lysosome identity alone,

Macroautophagy Solutions
Macroautophagy is a conserved lysosome-dependent degradation pathway in which cytoplasmic material is sequestered into double-membrane autophagosomes and delivered to lysosomes for degradation and recycling. The pathway supports cellular homeostasis during nutrient limitation, organelle stress, protein-aggregate accumulation, infection, differentiation, and tissue remodeling by coupling cargo sequestration, autophagosome maturation, lysosomal fusion, and degradation of cargo-derived macromolecules. The core molecular sequence includes initiation by nutrient- and stress-regulated autophagy machinery, autophagosome nucleation, LC3/ATG8-family conjugation to autophagosomal membranes, cargo selection through receptors such as SQSTM1/p62, autophagosome-lysosome fusion, and lysosomal degradation. LC3 was identified as a mammalian homolog of yeast Atg8 that localizes to autophagosomal membranes after processing, and p62/SQSTM1 was shown to connect ubiquitinated cargo with autophagic degradati

Liver Histomorphometry
Liver histomorphometry is a quantitative histological approach used to measure structural alterations in hepatic tissue, including parenchymal loss, steatosis, fibrosis, and vascular remodeling, by combining stained tissue section analysis with stereological or computerized image-based measurements. Classical morphometric frameworks quantify volume fractions of liver compartments and fibrotic regions using systematic sampling and image analysis, enabling objective comparison of pathological changes across experimental groups. These approaches are widely applied in liver cirrhosis and fibrosis studies to reduce subjectivity in histological scoring and improve reproducibility of tissue evaluation. Recent methodological advances integrate automated image analysis and radiomics-based extraction of histological features from standard liver stains (e. g. , H&E and fibrotic stains), enabling quantitative correlation between morphometric features and fibrosis stages in non-alcoholic fatty live

Lipid Droplets: Oil Red O/Sudan Dye Lipid Staining
Lipid droplets are intracellular organelles with a neutral-lipid core that stores triacylglycerols and sterol esters, and Oil Red O or Sudan dyes detect these hydrophobic lipid deposits by partitioning into retained lipids in fresh or frozen specimens. Oil Red O stains neutral triglycerides and lipids in frozen tissue sections or air-dried cytologic preparations, while Sudan Black B has also been used as a histochemical fat stain for lipid-rich tissue structures.
