Flow cytometric analysis of BALB/c mouse bone marrow labeled with Anti-Mouse CD71 at 1/500 dilution (1 μg) / (right panel) compared with a Mouse IgG2a, κ Isotype Control / (left panel). Goat Anti- Mouse IgG Alexa Fluor® 488 was used as the secondary antibody. Then cells were stained with TER-119 – PE antibody separately. Flow cytometry and data analysis were performed using Agilent NovoCyte Quanteon and FlowJo™ software.

Background
CD71, also known as the transferrin receptor 1 (TfR1), is a type II transmembrane glycoprotein that plays a crucial role in cellular iron uptake by binding to transferrin, which facilitates iron transport into the cell. This receptor is highly expressed on rapidly proliferating cells, including erythroid precursors, activated immune cells, and cancer cells, as these cells require significant iron for DNA synthesis and metabolic processes. In clinical contexts, CD71 is used as a marker for identifying immature red blood cells (such as proerythroblasts and reticulocytes) and is also associated with aggressive tumor growth in various cancers, including pancreatic and colon cancers. Additionally, studies have shown that CD71 expression on neutrophils can be linked to poor prognosis in pancreatic ductal adenocarcinoma (PDAC) patients, indicating its potential as a prognostic biomarker.
