Here, we present a protocol for generating chemoresistant cells using a dose-escalation approach, followed by a CRISPR/Cas9-based screen using a focused sgRNA library targeting epigenetic modifiers to identify regulators of acquired chemoresistance. The protocol also provides multiple optimization points tailored to chemoresistant cell models, offering a robust framework for researchers investigating resistance mechanisms.

Recent development in gene targeting tools makes production of knockout (KO) rabbits possible. In the present work, we generated five Apolipoprotein (Apo) C-III KO rabbits using Zinc Finger Nucleases (ZFN). This work demonstrated that ZFN is a highly efficient method to produce KO rabbits.
FAQs
Leukemia inhibitory factor matters because it links a media component to a defined intracellular signaling outcome. In mouse embryonic stem cells, it can activate the JAK/STAT3 pathway, which helps preserve pluripotency, the capacity to remain in an undifferentiated state. Including this factor therefore supports maintenance of the desired cell state rather than merely supplying general nutritional support.
Different supplement classes address distinct culture requirements. Amino acids and energy sources provide resources for cellular activity, while antioxidants and other protective components help support cell survival. Growth factors and signaling factors add regulatory control. Considering these roles separately helps researchers design a formulation that supports both proliferation and the intended state of the cells.
The balance between self-renewal and differentiation depends on how nutrients, protective components, and signaling factors are combined and adjusted. Conditions that preserve pluripotency can support continued expansion, whereas changing regulatory signals can make the culture useful for differentiation studies. This tunability allows the same general supplementation strategy to serve distinct experimental goals in stem cell biology.
Defined formulations improve culture consistency because they let researchers control the amounts and types of nutrients, growth factors, and protective components supplied to cells. That control reduces ambiguity about which environmental inputs support survival, proliferation, self-renewal, or differentiation. In stem cell experiments, more consistent conditions make comparisons among expansion, reprogramming, gene-editing, and differentiation studies more meaningful.
A practical workflow begins by selecting the specialized culture medium and then adding the required defined nutrients, growth factors, and protective components. Researchers can adjust amino acids, energy sources, antioxidants, and signaling factors according to whether the goal is maintenance, expansion, or differentiation. Careful adjustment creates the controlled culture conditions needed for consistent stem cell experiments.
Knockout Media Supplementation is useful across several stages of stem cell research. It supports expansion, reprogramming, gene-editing experiments, and differentiation studies. In developmental biology, these controlled culture conditions help researchers examine changes in cell state, while regenerative medicine research benefits from approaches that maintain or guide stem cells under defined conditions.
