A tumour line is chosen for a genotype rather than a tissue: a driver mutation, a receptor status or an immune context. Every line here needs short tandem repeat authentication on arrival and a recorded passage history, because drift and cross contamination are documented in this field rather than hypothetical.
baf3 cells and the growth factor dependence that defines them
baf3 cells depend on interleukin 3 for survival, which is exactly why they are used: a transfected kinase that makes them factor independent is a functional assay for that kinase's activity, and the readout is survival without the cytokine. Withdrawal controls and the parental line carried in parallel are what make such a claim interpretable.
An id8 cell line and the syngeneic ovarian model
An id8 cell line grows in an immunocompetent matched mouse strain, which is what makes it the standard syngeneic ovarian model and why strain matching is absolute. Intraperitoneal implantation produces ascites over weeks, so the route and the cell number are as much a part of the model as the line, and the immune infiltrate is usually the point.
A t47d cell line and hormone receptor status
A t47d cell line is hormone receptor positive, which is why it is paired with a receptor negative line in endocrine therapy work, and its progesterone receptor expression is the feature that separates it from the other common positive line. Phenol red free medium and charcoal stripped serum are what make a hormone experiment in it meaningful.
A bxpc3 cell line and pancreatic models
A bxpc3 cell line is pancreatic and, unusually for that disease, wild type for the common driver, which is why it is the comparator against mutant lines rather than a representative model. Growth is slow and the line is often used in orthotopic work, where the implantation site changes the phenotype enough to change conclusions.
A k562 cell line and the fusion it carries
A k562 cell line carries the chronic myeloid leukaemia fusion kinase, which is what makes it the standard model for that inhibitor class and a reference line in cytogenetics. It is also the classical target in natural killer cytotoxicity assays because it lacks class I surface expression, and those two uses have nothing to do with each other.
A panc 1 cell line and what it is used for
A panc 1 cell line is a pancreatic line carrying the common driver mutation, used for signalling and drug work rather than as a model of the tumour's stroma, which is the disease's defining feature and is absent in monoculture. Co-culture or organoid formats are what address that, and a monoculture result should say so.
An rko cell line and mismatch repair status
An rko cell line is colorectal and mismatch repair deficient, which is why it is chosen for microsatellite and immune checkpoint work and why its isogenic corrected derivatives are the real value. A comparison against a repair proficient line rather than against a different tissue is what makes such an experiment controlled.
An ht-29 cell line and differentiation in culture
An ht-29 cell line can be pushed toward an enterocyte like phenotype by changing the carbon source, which is why the same line appears as a barrier model and as a proliferating tumour line in different papers. The medium and the days after confluence therefore decide what is being measured, and both belong in the method.
Questions people ask about molm13 cell line
Why authenticate a line that came from a repository?
Because drift and cross contamination happen in the laboratory. A short tandem repeat profile on arrival is the baseline.
Does a syngeneic model need a matched strain?
Absolutely. The point of the model is an intact immune system, which only the matching strain provides.
Why do two papers describe one line differently?
Medium, confluence and days in culture change the phenotype. Those belong in the method rather than the line's name.
