This protocol describes a detailed method for efficient generation of integration-free iPSCs from human adult peripheral blood cells. With the use of four oriP/EBNA-based episomal vectors to express the reprogramming factors, KLF4, MYC, BCL-XL, or OCT4 and SOX2, thousands of iPSC colonies can be obtained from 1 mL of peripheral blood.

Ex Vivo Expansion of Natural Killer Cells from Peripheral Blood Mononuclear Cells

This video demonstrates a technique for the expansion of natural killer (NK) cells directly from peripheral blood mononuclear cells (PBMCs) using a feeder cell line. PBMCs are co-cultured with genetically modified lymphoblastoid feeder cells expressing membrane-bound interleukin-21 (mIL-21), and the culture is supplemented with the cytokines interleukin-2 (IL-2) and interleukin-15 (IL-15). Together, this cocktail of ligands leads to the prolonged expansion of NK cells with high purity.
FAQs
Density-gradient centrifugation is important because it enables researchers to separate the desired mononuclear fraction from red blood cells and granulocytes. This enrichment makes subsequent measurements more interpretable by reducing the presence of cell populations that are not the primary focus. The resulting preparation can then support analyses of immune activation, cytokine production, or host-pathogen interactions.
The mixed population supports complementary immunology questions rather than a single-cell readout. Lymphocytes, monocytes, and other mononuclear cells can be examined together to study innate and adaptive responses, cellular activation, and cytokine production. Keeping these functions in the same experimental resource helps investigators evaluate how cord blood immune cells respond during infection-related or activation-focused studies.
Cord blood mononuclear cells are particularly informative for questions about early immune development. Their cord-blood origin provides a window into immune characteristics at an early developmental stage, while their accessible collection supports human studies without invasive procedures. This makes them useful for examining developmental immune behavior in disease modeling, infection research, or immunotherapy evaluation.
A typical workflow begins with obtaining umbilical cord blood, applying density-gradient centrifugation, and collecting the mononuclear-cell fraction after separation from red blood cells and granulocytes. Researchers can then use the isolated preparation in studies of cytokine production, cellular activation, innate or adaptive responses, and host-pathogen interactions. The separation step is therefore central to obtaining a suitable experimental input.
These cells are useful when a study requires human immune material for more than one research objective. Investigators can apply them to transplantation research, disease modeling, and evaluation of immunotherapies, while also examining infection-related immune responses. Their ethical accessibility and collection without invasive procedures make them a practical resource when obtaining relevant human cells is an important consideration.
In infection studies, measurements can focus on how the cells activate, produce cytokines, or participate in host-pathogen interactions. These readouts help characterize both innate and adaptive immune responses rather than limiting the experiment to pathogen presence alone. Consequently, cord blood mononuclear cells can connect cellular behavior with broader questions about human immunity and the development of immunotherapies.
