Source: Ricardo Mejia-Alvarez, Hussam Hikmat Jabbar and Mahmoud N. Abdullatif, Department of Mechanical Engineering, Michigan State University, East Lansing, MI Owing to the non-linear nature of its governing laws, fluid motion induces complicated flow patterns. Understanding the nature of these patterns has been the subject of intense scrutiny for centuries. Although personal computers and supercomputers are extensively used to deduce fluid flow patterns, their capabilities are still...

An In Vitro Assay to Assess CAR T Cell Cytotoxicity against Tumor Spheroids

2025
This video demonstrates an in vitro assay evaluating the cytotoxic effects of CAR T cells on 3D tumor spheroids expressing fluorescent proteins. This assessment utilizes the Annexin V red fluorescent probe, which binds to exposed phosphatidylserine residues on the outer leaflet of apoptotic cancer cells after interactions with CAR T cells. The red fluorescence emitted by the probe aids in distinguishing these cells from healthy ones emitting green fluorescence.

Spheroid Generation from Cell Lines: A Three-Dimensional (3D) Cell Culture Method
0 Views •
2023
Spheroids are a type of 3D cell culture model used to more accurately represent a cell’s environment compared to 2D cell culture monolayer models. In the example protocol, we will see scientists generate spheroids from a colorectal cancer cell line and apply live-cell imaging to track the spheroids’ growth.
FAQs
Dependencies establish the order in which engineering activities can proceed. For example, design, prototyping, testing, manufacturing, and deployment may need to occur in a linked sequence rather than independently. Mapping these relationships helps teams recognize which activities rely on earlier work, coordinate handoffs, and assess how a delay in one task could influence later milestones and the planned completion date.
Critical path analysis identifies the sequence of activities that controls project completion. Because delays along this controlling sequence can affect the overall delivery date, engineers can focus monitoring and coordination on those tasks. This approach complements a broader timeline by showing which activities have the greatest scheduling significance and helping teams evaluate the consequences of changes or delays.
By placing activities, durations, dependencies, and deadlines in relation to one another, a timeline makes overlapping demands easier to detect. Engineers can identify schedule conflicts between design, testing, manufacturing, or deployment activities before they disrupt the project. The resulting visibility supports coordination among teams and helps align planned work with available resources and required milestones.
A design change can alter task relationships, durations, deadlines, or the sequence leading to deployment. Reviewing the timeline after such a change helps engineers trace its potential effects on later activities rather than treating it as an isolated adjustment. This evaluation supports decisions about coordination, resource allocation, cost, safety, and whether delivery objectives remain achievable.
Engineers should identify the project tasks, estimate their durations, connect dependencies, and establish relevant deadlines and milestones. These elements provide the structure needed to organize work across design, prototyping, testing, manufacturing, and deployment. Recording them in a planning tool, such as a Gantt chart, also creates a basis for tracking progress against the intended objectives.
A timeline coordinates successive project phases from design through deployment while showing how planned work should progress. Teams can use it to compare actual progress with objectives, communicate responsibilities and timing, and recognize when activities require adjustment. Applying the same schedule framework across phases helps connect technical work with manufacturing and delivery expectations.
Beyond showing whether work is on schedule, a timeline helps teams examine resource allocation, schedule conflicts, and the effects of delays or design changes. These effects may extend to project cost, safety, and delivery. The resulting record supports clearer communication and provides a structured way to judge progress against planned engineering objectives.
