Mononucleated Cells

Mononucleated cells are cells containing a single nucleus, a defining structural feature that supports their identification and use in biomedical research and bioengineering. In blood-processing workflows, these cells can be separated from whole blood by density-gradient centrifugation, which distributes components according to buoyant density and allows the mononuclear fraction, including lymphocytes and monocytes, to be collected at the gradient interface. Researchers use isolated mononucleated cells to study immune responses, evaluate biomaterials, model disease, and develop cell-based therapies. Their accessibility and functional diversity make them valuable for tissue engineering, diagnostics, and regenerative medicine.

Generation of Immature, Mature and Tolerogenic Dendritic Cells with Differing Metabolic Phenotypes

0 Views •

Cited by 37 •

2016

Immature dendritic cells can be selectively differentiated into tolerogenic or mature dendritic cells to regulate the balance between immunity and tolerance. This work presents a means to generate from immature monocyte derived dendritic cells (moDCs), in vitro tolerogenic and mature moDCs that differ in metabolic phenotypes.

2007

This protocol details the derivation of transplantable hematopoietic stem cells from mouse embryonic stem cells (ESC) and their subsequent injection into lethally irradiated recipient mice. Briefly, ESC are differentiated as embryoid bodies, which are then infected with retroviral HoxB4 and co-cultured with OP9 stromal cells and hematopoietic cytokines.

Studying Proteolysis of Cyclin B at the Single Cell Level in Whole Cell Populations

Cited by 2 •

2012

Metaphase to anaphase transition is triggered through anaphase-promoting complex (APC/C)-dependent ubiquitination and subsequent destruction of cyclin B. Here, we established a system which, following pulse-chase labeling, allows monitoring cyclin B proteolysis in entire cell populations and facilitates the detection of interference by the mitotic checkpoint.
