Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for effective markers to assess the quality of stem cells, particularly mesenchymal stem cells, for use in cell therapy products to treat immune-related diseases.
Innovation Solution
A composition and kit using an agent to measure the expression level of the CD71 protein, which helps in selecting high-quality stem cells by determining their CD71 expression levels, thereby identifying cells suitable for cell therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stem cells are selected without specific quality markers, then the selection process is simple, but the therapeutic efficacy and quality consistency cannot be ensured
Solution Approach 1:
The patent uses fluorescently labeled antibodies that bind to CD71 protein on stem cell surfaces, causing detectable fluorescent signal changes. This allows quality assessment through fluorescence intensity measurements, where cells with appropriate CD71 expression levels emit specific fluorescence signals, enabling reliable selection of high-quality stem cells for therapy
Solution Approach 2:
The patent replaces manual or simple filtration-based cell selection methods with flow cytometry technology. The mechanical/manual sorting process is substituted by an automated optical detection system that measures fluorescent signals from CD71-specific antibodies, enabling precise and consistent quality-based cell selection without complex manual procedures
2Measurement precision
If traditional stem cell selection methods are used, then the process is straightforward, but quality assessment precision is insufficient
Solution Approach 1:
The patent introduces CD71-specific antibodies as intermediary molecules that bind to the CD71 protein on stem cell surfaces. These antibodies serve as mediators between the CD71 marker and the detection system, translating cellular quality characteristics into measurable fluorescent signals that can be precisely quantified by flow cytometry
Solution Approach 2:
The patent transforms the quality assessment from subjective or crude measurements to precise quantitative analysis by measuring fluorescent signal intensity parameters. The concentration and distribution of CD71 protein expression are converted into measurable fluorescence parameters, enabling precise differentiation of stem cell quality states through numerical data
