How To Select Cancer Cell Lines For Your Experiments?
Before choosing cancer cell lines for your experiments, it’s essential to evaluate a few critical factors. Selecting the right cell line impacts the reliability and relevance of your results. Here are five key questions to consider to ensure that your chosen Cancer Cell Line is credible, contamination-free, biologically appropriate, genetically stable, and suitable for your specific experimental requirements.
Here is a list of a few questions that you must ask before selecting cancer cell lines for your experiments:
1. Is it a credible cell line?
It is of utmost importance that you ask the question of whether a certain line is what it is claimed. You would be shocked to know that there are over 500 cell lines that have been masked and misidentified in the Register of Misidentified Cell Lines (v13 April, 2024). You sure can obtain cell lines from third-party cell banks like Kosheeka and NCCS. Even when you obtain these cell lines it is best to have them annually assessed using STR profiling.
If you start an experiment with a commercial cell line like BCC1/KMC, it could be you are actually not working with them. The only real way for you to make sure that you actually pick up cell lines that you need is to always go for a certificate of authentication and do STR profiling. STR profiling might be a long process, but doing it is necessary to ensure that you have an authentic biological model that works as it is intended.
2. Is it free of contamination?
Yes, even if you get an authentic line, it is necessary to ensure you have contaminant free cell lines. A simple bacterial infection can put added stress on these cell lines that will make their biology change. Now, if you get an infection that alters the biology, your experiments will change. That's because the microorganisms are so small and don't look like other bacteria (they don't have a solid wall, instead they have a plasma-like shape).
Reliable cell providers will provide cell stocks confirmed to be mycoplasma-free. When the contamination status of a cell stock is uncertain, it is advisable to cultivate it in a quarantine setting and confirm its "clean" status before transferring it to public circulation. This approach minimizes the chance of mycoplasma contaminating a whole cell culture laboratory.
3. What is the passage number of cells?
For in vitro cultures you will notice that their is genetic instability, and Cancer Cell Lines start to accumulate these genetical errors. Even a recent study from Domcke et al., found "pronounced differences in molecular profiles between commonly used ovarian cancer cell lines.This is likely attributable to the age and resultant prolonged culture of particular lines, resulting in their divergence from the original malignancies.
To mitigate this, it is advisable to sustain cell stocks at the lowest passage feasible and to routinely (every 2-3 months) start cell culture with a new vial. Temporal alterations in cell lines may, in some instances, be visibly discernible; for instance, prolonged culture of U87 cells might result in a diminished monolayer and the formation of spheroids from the flask surface.
4. Does it show the right biology?
Your choice of cell line will almost definitely be determined by the question or problem you're attempting to address. If you're studying a certain disease condition, the closer the cell line resembles that sickness, the better.
Even across illness kinds, careful selection is essential. For example, if you're studying breast cancer, you might be interested in only triple negative breast cancer, or you might want to look at a variety of subtypes. Your research objectives will guide your choices.
If you are studying a disease, the Cancer Cell Line Encyclopaedia (CCLE) is a fantastic resource for identifying a cell line that expresses a specific biomarker or has a specific genetic abnormality. The CCLE offers public access to genomic data, analysis, and visualization for about 1000 cell lines, allowing you to not only choose an appropriate cell line but also place any results you generate within the context of the CCLE's enormous data set.
If your focus is on basic biology rather than disease biology, you will frequently come across a model line from which a body of work has been created. By taking this same approach, discoveries can be placed in the context of existing scientific knowledge.
This method of selection, however, produces a self-perpetuating bias toward published cell lines, which may not have been chosen because they are the best suitable. Unsurprisingly, the age of a cell line can influence how frequently it appears in the literature, as with the first immortalized cell line, HeLa cells, which have been widely employed (their simplicity of cultivation no doubt contributing to their popularity).
The best method is to identify numerous cell lines and show results over a panel. This not only increases confidence in the results, but it also eliminates the idea that they are simply a quirk of a specific line.
5. Is it suitable for your experiment?
The selection of a cell line for any experiment necessitates a balance between identifying the most physiologically relevant model and opting for a cell line that is manageable for experimentation.
Cultural conditions, growth rate, transfectability, morphology, subcellular structure (for microscopy), and cost significantly influence the studies conducted and their probable success.
Induced pluripotent stem cells (iPSCs) may provide a more "normal" model compared to cancer cell lines; however, the demanding cell culture protocols and related expenses may render these lines unsuitable for certain laboratories.
The objective is to identify the optimal compromise—a cell line that has comparable biological characteristics, facilitates rigorous and efficient scientific inquiry, and withstands validation in external laboratories.
Detailed culture conditions and growth rates are provided by Kosheeka for numerous widely used cell lines.

Human Blood-Derived CD34+ Cells: Advancing Stem Cell Therapy Research
Umbilical cord-derived mesenchymal stem cells: High-quality, Ethically-Sourced, and Rapidly Delivered
Stem cells for scar treatment are explored due to their regenerative properties. Wound healing is a routine process to repair an injury. However, it is a complex process involving different cells and phases. The imbalance in the process can either lead to scar or fibrosis. In both cases, tissue loses its original structure and function. While it has modest implications in subcutaneous tissue, its presence in internal organs can severely impact its function. The scar formed in the tissue is more susceptible to injury.
Therefore, research is focusing on a treatment that can drive scarless healing. In the last decades, regenerative medicine has caused a shift in the therapeutic approach from merely treating the disorder to stimulating tissue repair. Stem cell therapy has been at the forefront of this approach. In this blog, let’s explore how wound healing occurs and whether Stem Cells Can Heal Scar Tissue.
Types of Primary Cells
The Dynamic Role of Human Primary Endothelial Cells in Human Physiology
Human primary endothelial cells have been employed extensively in pathophysiology and therapeutic research. These cells are the basic unit of any blood vessel—capillaries, arteries, and veins. As a core component of the circulatory system, they are integrated into each organ. Their role extends from being a mere barrier to regulating tissue homeostasis, vessel integrity, disease pathogenesis, immune modulation, etc. The significance of endothelial cells in tissues has even led to their incorporation into 3D structures.
Human Primary Endothelial Cells: In Vitro Culture Endothelial cell culture includes primary cells and cell lines. For decades, endothelial research has mostly employed human umbilical vein endothelial cells (HUVECs). They are readily available and relatively easy to isolate. Endothelial cell lines like HMEC-1 and EA.hy926 have also gained popularity for in vitro research due to their infinite proliferation. In the 2D culture, these cells exhibit a cobblestone morphology with characteristic surface markers vWF and CD31. Their culture might suffer from a few setbacks: Low/No Adherence: Endothelial Cells can adhere to standard tissue culture flasks. However, sometimes issues with their attachment arise. It can be resolved by coating flasks with gelatin or utilizing coated flasks explicitly manufactured for these cells. Seeding higher cell density can enhance cell-cell contact, which is vital for cell adherence, survival, and growth. Cell Viability: Researchers might notice low cell viability after a few passages. This could occur due to several factors, such as the medium. Typically, endothelial cell growth medium (ECGM), M199, or DMEM (with F12) are suitable choices for endothelial culture. However, the addition of growth factors like heparin and VEGF can improve cell growth.
Function In the past, endothelial cell definition described them as the mere lining of vessels that serve as a barrier between tissue and blood. This barrier has been prominent in delivering drugs to the brain. Therefore, much research on these cells was restricted to cardiovascular and brain applications. However, growing studies have also revealed their diverse functions, shifting the perspective surrounding them. Endothelial cells are vital for regulating the vascular tone, tightly controlling coagulation and vasodilation. They not only aid in immune cell trafficking but also mediate immune response. Their role in angiogenesis is indispensable in wound healing and tissue regeneration.
Endothelial Heterogeneity Biomedical research also shed light on intriguing aspects of the endothelium. Endothelium varies in phenotype and genotype throughout circulation or in tissues. The presence of different types of blood vessels was known. However, the interesting fact was the different morphology and behavior of the endothelium. Endothelium contains pores or fenestrations, which add to the layer's already complex permeability. Furthermore, the absence of a basement membrane beneath the endothelium enhanced permeability, allowing cell passage. This property is more prevalent in the liver and spleen due to their functional requirements.
On diving deep, changes in the genetic profile of endothelial cells present in various tissues and during varying physiological conditions became evident. For instance, VCAM1 expression on the endothelium increases during inflammation. Such studies established that they adapt to the tissue requirements. Therefore, isolation of Endothelial Primary Cells extended to other tissues and vessel types, enabling the study of tissue-specific behavior.
Research Applications Disease: When endothelial cells lose their ability to regulate blood flow or barrier integrity, pathologies such as hypertension, atherosclerosis, diabetes, and chronic inflammatory conditions arise. They also respond to injury, control inflammation and facilitate healing. Previously, the research concentrated on cardiovascular and neurological fields. However, it has expanded to various tissues, such as pulmonary dysfunction, visual disorders, and ischemic diseases. Cancer: Disrupted vessel integrity grants high permeability to tumor vasculature. Scientists have exploited this feature to develop nanomedicine with higher chances of biodistribution to tumors. This minimizes harm to other normal tissues. These nanomedicines include angiogenic drugs that target the tumor vessels and halt their growth. Tissue Engineering: The beginning of 3D culture utilized cells from corresponding organs. However, the growing importance of the endothelium led to its inclusion in co-culture and 3D models. The functioning and survival of these constructs improved, raising the use of these cells. Angiogenesis: Many disorders occur due to endothelium dysfunction, such as stroke, limb ischemia, liver disorders, etc. The repair and formation of vessels follows the process of angiogenesis. Therefore, scientists are also focusing on this process to formulate novel therapies.
In Conclusion Human Primary Endothelial Cells have become a focal point of research to understand vascular biology, inflammation, disease mechanisms, and vessel repair. Several anti-angiogenic medications and vasodilators are already available in the market for the treatment of various disorders. The heterogeneity of the endothelium alludes to its crucial role in tissue and vessel functioning. It resulted in their incorporation into a 3D model to improve cell survival and function.
