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

2025
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.

In this video, we describe a protocol for human primary T cell activation. The incubation of naïve T cells with magnetic beads coated with anti-CD3 and anti-CD28 antibodies, followed by interleukin-2 or interleukin-15 treatment, leads to the activation of naïve T cells and their differentiation and proliferation into effector or memory T cells.

In this video, we demonstrate the isolation of lamina propria mononuclear cells from murine colonic tissue by enzymatic digestion using collagenase E and silica-based density separation media gradient separation. The isolated mononuclear cells can be used for subsequent downstream analysis.
FAQs
Surrounding niches control progenitor-cell behavior through coordinated cytokines, growth factors, and adhesion signals. These cues influence whether cells remain viable, renew themselves, migrate to another location, or begin differentiating toward specialized lineages. Studying these interactions helps explain why the same cell population may behave differently depending on its tissue environment and supports evaluation of regenerative or transplantation strategies.
Cytokines and growth factors provide regulatory instructions, while adhesion signals connect cells with their local supportive environment. Together, these inputs affect survival, self-renewal, migration, and differentiation rather than acting as isolated triggers. Measuring responses to such signals can reveal how progenitor populations maintain tissue function or contribute to the restoration of blood-cell production.
Migration allows these precursor cells to respond to signals from their surrounding niche and reach locations where maintenance, repair, or blood formation is needed. Adhesion cues and soluble regulators help shape this movement and its consequences. Examining migration therefore provides information about how cells interact with tissues and how transplantation approaches might influence their distribution and activity.
Medical research examines these cells in bone marrow and peripheral blood samples to characterize hematopoietic function, meaning the capacity to support blood-cell production. Investigators can assess cellular behavior and responses to regulatory signals in these sample contexts. The resulting information helps connect progenitor-cell activity with normal regeneration, impaired blood formation, and potential therapeutic strategies.
Comparing progenitor-cell findings from bone marrow or peripheral blood can help researchers characterize hematopoietic function and examine how cells participate in blood formation. Such analyses also provide a basis for evaluating measurable cellular responses. In medicine, this information supports investigation of disorders that impair regeneration or blood-cell production and informs studies of transplantation.
They are relevant when researchers need to evaluate how precursor cells survive, migrate, renew themselves, or differentiate after exposure to a supportive environment or transplantation strategy. Their measurable responses can help assess whether an approach promotes useful cellular activity. These studies also contribute to understanding disease mechanisms and the broader potential of regenerative medicine.
