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.

Here we present methodology for the production of a focal stroke in murine white matter by local injection of an irreversible endothelial nitric oxide synthase (eNOS) inhibitor (L-Nio). Presented are two stereotactic variations, retrograde neuronal tracing, and fresh tissue labeling and dissection that expand the potential applications of this technique.

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.
FAQs
Different leukocyte populations contribute through complementary mechanisms rather than a single response. Innate immune cells can engulf material through phagocytosis, B lymphocytes produce antibodies, and T lymphocytes carry out targeted cellular responses. This division of labor allows clinical interpretation to move beyond a total white blood cell count and consider which population may be changing.
Phagocytosis gives innate immune cells a direct way to engulf material during an immune response. Antibody production by B lymphocytes and targeted cellular responses by T lymphocytes represent different forms of immune activity, so they should not be treated as interchangeable. Recognizing these distinctions helps explain why a differential can add information beyond the overall leukocyte count.
Bone marrow is important not only because it produces these cells, but also because clinical measurements can provide information about marrow function. After production, leukocytes circulate through blood and lymph, creating routes through which their distribution can be considered clinically. This connection makes white blood cell findings relevant to both immune activity and disorders affecting blood-cell production.
Clinical evaluation commonly considers two related measurements: the overall white blood cell count and the differential, which examines changes in specific cell populations. These results are interpreted as indicators of inflammation, infection, immune disorders, or bone marrow function. The resulting pattern can support diagnostic assessment rather than relying on one aggregate value alone.
A differential can reveal that the overall leukocyte count is accompanied by a change in a particular cell population. That added detail may support assessment of infection, inflammation, immune disorders, or bone marrow function. In practice, clinicians can use the findings alongside broader clinical evaluation to support diagnosis and treatment decisions, rather than interpreting the total count in isolation.
Repeated measurements allow clinicians to monitor whether blood-cell findings change as disease progresses or treatment decisions are made. Because the count and differential provide information about both total leukocyte levels and specific populations, trends can offer a more informative view than one isolated result. This monitoring role connects laboratory findings with ongoing clinical assessment.
