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.

Integration by Parts: Indefinite Integrals

2026
Integration by parts is a fundamental technique in calculus for evaluating integrals involving the product of two functions. It is particularly useful when direct integration is not feasible. The method is based on the product rule for differentiation, which states that the derivative of a product equals the derivative of the first function times the second, plus the first function times the derivative of the second. By integrating this identity and rearranging terms, the integration by parts...

Integration by Parts: Definite Integrals

Definite integrals involving the product of two functions over a fixed interval can be evaluated using integration by parts. This method rewrites the integral as the difference of a product evaluated at the endpoints and a remaining definite integral that is often simpler to compute.A representative example is the definite integral of the inverse tangent function. Since there is no direct integration formula for arctan x, the integrand is rewritten as a product of arctan x and the constant...

Induced pluripotent stem cells (iPSCs) represent a source of patient-specific tissues for clinical applications and basic research. Here, we present a detailed protocol to reprogram human peripheral blood mononuclear cells (PBMNCs) obtained from frozen buffy coats into viral-free iPSCs using non-integrating episomal plasmids.
FAQs
Damage to the plasma membrane can disturb the ion gradients that cells use to regulate transport and coordinated activity. It may also cause membrane leakage, allowing the internal environment to lose its normal control. In medical research, these changes provide evidence that physical injury, toxins, infection, inflammation, or metabolic imbalance has affected cellular function.
Cell integrity depends on coordinated support from several internal systems rather than on the membrane alone. The cytoskeleton helps preserve cellular structure, organelles support functions such as energy production, and regulatory systems coordinate responses to stress. Dysfunction in one component can therefore contribute to impaired signaling, organelle dysfunction, or broader loss of cellular performance.
Stress can initially interfere with ion gradients, transport, signaling, or energy production. If the disturbance is severe or sustained, these linked failures may progress from membrane leakage and impaired signaling to organelle dysfunction and cell death. This progression helps explain why cellular injury can affect tissue and organ health beyond the initially damaged cells.
Assessment can indicate whether cells have maintained their normal boundaries and coordinated functions after exposure to a harmful condition. Findings such as membrane leakage, impaired signaling, or organelle dysfunction can help researchers evaluate the extent of tissue damage. This information supports interpretation of how injury affects tissues and organs in medical studies.
Researchers can use changes in cell integrity to determine whether a drug or other treatment harms cells. Evidence of membrane leakage, disrupted transport, impaired energy production, or organelle dysfunction may signal unwanted toxicity. Such evaluation contributes to safer therapies by identifying damaging effects before treatment responses are interpreted as beneficial.
Monitoring cellular condition can connect disease-related stress with changes in tissue and organ function. It also allows researchers to compare whether a treatment preserves, worsens, or improves cellular performance over time. In medicine, these observations support disease-progression studies, treatment-response assessment, and the development of more accurate models of human health.
