Establishment of human models of the blood-brain barrier (BBB) can benefit research into brain conditions associated with BBB failure. We describe here an improved technique for preparation of a contact BBB model, which permits coculturing of human astrocytes and brain endothelial cells on the opposite sides of a porous membrane.

The cell membrane modification of red blood cells (RBCs) with hyperbranched polyglycerol (HPG) is presented. Modified RBCs were characterized by aqueous two phase partitioning, osmotic fragility and complement mediated lysis. The camouflage of surface proteins and antigens was evaluated using the flow cytometry and Micro Typing System (MTS) blood phenotyping cards.

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.

Assaying Blood Cell Populations of the Drosophila melanogaster Larva

Drosophila blood cells, or hemocytes, cycle between resident sites and circulation. In the larva, resident (sessile) hemocytes localize to inductive microenvironments, the Hematopoietic Pockets, while circulating hemocytes move freely in the hemolymph. The goal of this protocol is the standardized isolation and quantification of these two, behaviorally distinct but interchanging, hemocyte populations.
FAQs
Specificity comes from the label’s interaction with a cellular target. Antibodies or other tags can bind surface markers, while some fluorescent dyes enter cells under controlled conditions. When labeled cells are analyzed, the detectable signal is interpreted alongside physical characteristics, allowing distinct populations to be identified rather than treating blood cells as a single uniform group.
Fluorescent dyes provide a detectable signal by entering cells under controlled conditions, whereas antibodies identify cells through binding to surface markers. These approaches therefore emphasize different cellular features: intracellular access for some dyes and molecular surface identity for antibodies. Selecting between them depends on which characteristics researchers need to distinguish, count, separate, or track.
Combining physical and molecular characteristics improves the resolution of cell identification. A cell’s physical properties provide one basis for distinction, while a label reveals a relevant molecular feature such as a surface marker. Instruments such as flow cytometers can evaluate these signals together, helping users resolve specific blood cell populations for clinical classification or research analysis.
Controlled labeling conditions help ensure that detectable tags interact with cells in a consistent manner. This consistency matters because inaccurate or uneven labeling can reduce confidence in population identification, counting, separation, or tracking. In clinical and research workflows, maintaining control during labeling supports clearer instrument measurements and more dependable interpretation of cellular differences.
A typical workflow begins by selecting the blood cell population or characteristic of interest, followed by applying an appropriate detectable tag under controlled conditions. The labeled cells are then examined with an instrument capable of distinguishing their signals and physical features. Results can support identification, counting, separation, or tracking, depending on the study objective.
Clinical laboratories use labeled blood cells for immune-cell profiling, leukemia and lymphoma classification, transfusion studies, and evaluation of treatment responses. In these settings, labeling provides information that helps distinguish relevant cell populations and improves diagnostic resolution. Its value lies in connecting detectable cellular features with clinical questions about disease classification, immune status, compatibility, or response.
In research, labeled populations can be followed to investigate cell behavior, lineage, and interactions in health and disease. Tracking a detectable tag allows investigators to associate observations with a defined cell population rather than an undifferentiated blood sample. This supports studies of how cells relate to one another and how their characteristics may change across biological conditions.
