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.

Endothelial colony forming progenitor cells (ECFCs) are a promising tool to study vascular homeostasis and repair.1,2 This paper introduces a novel animal-serum free method for isolation and expansion of ECFC from heparinised adult human peripheral blood with pooled human platelet lysate (pHPL) diminishing the risk of anti-bovine immunisation.
FAQs
The culture environment shapes expansion by combining nutrient media with growth factors and cytokines. These inputs promote cell survival and proliferation, while their specific effects can support self-renewal or lineage-specific growth. The selected combination therefore determines whether cultures favor maintaining blood-forming stem and progenitor cells or increasing a desired blood cell population for research or potential clinical applications.
Preserving self-renewal helps blood-forming stem and progenitor cells remain available for continued expansion, whereas unwanted differentiation can reduce that population and alter the intended culture outcome. Researchers therefore design conditions that encourage survival and proliferation without excessively directing cells into an undesired lineage. This balance is important when the goal is to maintain versatile cells for disease studies, therapy evaluation, or transplantation research.
The desired output determines which growth conditions are most relevant. Red blood cells, immune cells, and hematopoietic stem and progenitor cells require attention to different expansion goals, such as increasing a mature blood-cell population or preserving stem and progenitor characteristics. Linking the culture strategy to the intended cell type helps align proliferation, lineage-specific development, and later experimental or clinical use.
Selected cells are maintained in nutrient media and exposed to combinations of growth factors and cytokines. The media supports cell maintenance, while the added biological signals promote survival, self-renewal, or lineage-specific proliferation. Adjusting these components influences whether the culture produces more blood cells or preserves blood-forming stem and progenitor cells, making culture design central to expansion efficiency and cell function.
A typical workflow begins by selecting the blood cells or blood-forming stem and progenitor cells that match the research goal. The cells are then maintained under laboratory conditions in nutrient media and exposed to appropriate growth factors and cytokines. These conditions are intended to support survival, self-renewal, or lineage-specific proliferation, producing a population suited to the planned study or application.
Expanded cultures support several biological and biomedical goals. Researchers can use them to study blood development, model disease, and evaluate therapies, while expanded red blood cells or immune cells may also inform transfusion-related work. Maintaining or increasing hematopoietic stem and progenitor cells is relevant to transplantation research. Improving expansion efficiency and preserving function may further support personalized treatment development.
