Quantify the dose- and time-dependent progression of apoptosis versus necrosis in Jurkat T-cells exposed to the pan-kinase inhibitor staurosporine, using dual Annexin V-FITC / propidium iodide (PI) staining and flow cytometry to resolve viable, early-apoptotic, late-apoptotic, and necrotic populations.
Measure the directional 2D migration rate of NIH/3T3 fibroblasts across a defined cell-free gap while suppressing proliferation, to isolate migration from growth and test how a candidate compound (e.g., a Rho-kinase inhibitor) modulates wound closure.
Quantify cell-cycle phase distribution (sub-G1, G0/G1, S, G2/M) in HeLa cells following nocodazole-induced mitotic arrest, using ethanol fixation, RNase treatment, and propidium iodide DNA staining with doublet discrimination and univariate Dean-Jett-Fox modeling of DNA content.
Generate a clonal, scarless SOX2-GFP knock-in iPSC reporter line by electroporating Cas9 RNP plus donor template and isolating correctly targeted, karyotypically normal clones for live tracking of neural progenitor identity during differentiation.
Generate uniform U-87 MG glioblastoma spheroids and embed them in 3D collagen I to quantify collective and single-cell invasion over 72 h, testing whether an MMP inhibitor (GM6001) restrains the invasive front.
Determine the half-maximal inhibitory concentration (IC50) of doxorubicin in MCF-7 breast carcinoma cells using the CellTiter-Glo luminescent ATP assay across a 9-point dose-response, with rigorous plate-layout controls to generate a reproducible, low-variability cytotoxicity curve.
Dissociate mature iPSC-derived intestinal organoids into a viable single-cell suspension and profile transcriptomes by droplet scRNA-seq to resolve enterocyte, goblet, enteroendocrine, Paneth-like, and stem/progenitor populations and benchmark differentiation fidelity against primary intestine.
Use automated time-lapse microscopy and single-cell tracking to quantify the speed, persistence, and directionality of individual RFP-labeled MDCK cells during wound-directed collective migration, and test how an EGFR inhibitor (gefitinib) alters trajectory parameters beyond bulk gap closure.
Quantify CXCL12 (SDF-1)-directed invasion of MDA-MB-231 cells across a Matrigel-coated porous membrane, and determine whether an AMD3100 CXCR4 antagonist blocks chemotactic invasion, to assess the CXCR4-CXCL12 axis as an anti-metastatic target.
Establish a standardized release-criteria QC panel that confirms a candidate iPSC line is pluripotent (OCT4/SOX2/NANOG/SSEA-4/TRA-1-60), genomically stable, mycoplasma-free, and competent to form all three germ layers before use in downstream differentiation.
Generate a homogeneous population (>85% SOX17+/FOXA2+) of definitive endoderm from feeder-free human iPSCs in 4 days as the obligatory first stage for downstream pancreatic, hepatic, and intestinal organoid differentiation.
Quantify the mechanosensitive nuclear translocation of the transcriptional co-activator YAP in HaCaT keratinocytes seeded on soft versus stiff polyacrylamide hydrogels, using ratiometric confocal immunofluorescence to measure the nuclear:cytoplasmic (N:C) YAP intensity ratio at single-cell resolution.
Measure the rate and coordination of collective epithelial migration in MDCK monolayers closing a defined scratch wound, using phase-contrast time-lapse microscopy and particle image velocimetry (PIV) to quantify wound-closure kinetics and the spatial coherence of the migrating front under control versus Rho-kinase inhibition.
Measure fibroblast-mediated contraction of a free-floating collagen lattice as a functional readout of myofibroblast differentiation, and determine whether TGF-beta1 enhances and an ALK5 inhibitor (SB-431542) blocks gel contraction, modeling wound-bed remodeling and fibrosis.
Produce reproducible self-organizing cerebral organoids with defined cortical neuroepithelial rosettes and PAX6+ progenitor zones for modeling early human corticogenesis and neurodevelopmental disorders.
