The Key Role of CD140a Antibody in Cell Biology Research

Hits:33   Date: 6/7/2026

1. Concept of CD140a Antibody and Its Molecular Basis
CD140a antibody is a highly specific immunoglobulin that binds to CD140a (platelet-derived growth factor receptor alpha, PDGFRα)—a type III tyrosine kinase receptor with an extracellular domain (five immunoglobulin-like ligand-binding regions), transmembrane domain, and intracellular tyrosine kinase domain. Produced via hybridoma or recombinant DNA technology, it specifically recognizes CD140a epitopes. Classified into monoclonal (high uniformity, specificity) and polyclonal (multiple epitope recognition, high sensitivity) antibodies, its quality (specificity, affinity, titer) directly impacts experimental reliability.

2. Research Frontiers
CD140a antibody applications span cell biology, stem cell research, signal transduction, and disease modeling. Key frontiers include refining mesenchymal stem cell (MSC) sorting using CD140a combined with other markers (CD90, CD105) for high-purity isolation, and studying PDGFRα-mediated signaling in tumor stroma and fibrosis. Antibody engineering (nanobodies, bispecific antibodies) enhances detection sensitivity and reduces non-specific binding. Translational research explores CD140a as a diagnostic biomarker for diseases like fibrosis and cancer, with multi-omics integration deepening its biological function understanding.

 
3. Research Significance
CD140a antibody is indispensable for advancing cell biology and translational research. It enables precise identification and sorting of MSCs, supporting tissue engineering and regenerative medicine. In signal pathway studies, it facilitates analysis of PDGFRα-mediated signaling, uncovering mechanisms of cell proliferation and differentiation. For disease research, it aids in constructing accurate tumor microenvironment and fibrosis models, identifying therapeutic targets. Its potential as a clinical biomarker bridges basic science and clinical diagnosis, addressing unmet needs in disease detection and treatment monitoring.

4. Related Mechanisms, Research Methods, and Product Applications
4.1 Cell Identification and Sorting
CD140a antibody is a gold standard for MSC isolation:
Sorting Techniques: Immunomagnetic sorting or flow cytometry isolates CD140a-positive MSCs from heterogeneous populations, with optimized antibody concentration, incubation time, and temperature ensuring >85% osteogenic/chondrogenic/adipogenic differentiation efficiency.
Combined Markers: Used with CD90/CD105 to refine cell subpopulations, enhancing purity for tissue regeneration research.

4.2 Signal Pathway Research
It deciphers PDGFRα-mediated signaling:
Complex Analysis: Co-immunoprecipitation captures CD140a and interacting molecules, analyzing signaling complex composition.
Activation Tracking: Western blot detects ~170 kDa CD140a protein; phosphorylation-specific CD140a antibodies quantify receptor activation kinetics (peak phosphorylation 5 minutes post-ligand stimulation).

4.3 Disease Model Construction
CD140a antibody supports disease research:
Tumor Models: Labels and isolates cancer-associated fibroblasts (CAFs) in tumor stroma, establishing accurate tumor microenvironment models and tracing stromal cell origin/evolution.
Fibrosis Models: Quantifies PDGFRα-positive myofibroblasts in fibrotic lesions (pulmonary/liver fibrosis), correlating cell numbers with disease severity.

4.4 Future Development Directions
Antibody Engineering: Nanobodies and bispecific antibodies improve detection sensitivity and reduce non-specific binding.
Clinical Translation: Validation as a diagnostic biomarker for fibrosis, cancer, and other diseases.
Multi-Omics Integration: Combining with proteomics/transcriptomics to deepen PDGFRα function understanding.
