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.

Fun toy but not as durable as I hoped.
Color: Green
I just rescued a dog from the shelter. She is super sweet and playful but she loves to chew her toys so I needed to buy her ones more durable to play with. This toy caught my eye but I was concerned that it might be too large for my small 7 pound terrier mix. After receiving it, I really loved the colors and the way it looked and my dog loves playing with it. Everything about it is great except that within a few weeks of playing with it, she already managed to make a small tear in it. It's not to the point where I would take it away from her toy box but I just wish it was more durable.

Great for tug of war
Color: Green
All the arms make for a good tug of war toy. It’s tough enough that my 70 lbs lab can pull on it and it’s fine

Durable
Color: Green, Color: Green
We’ve had it for awhile now and it’s still (mostly) in one piece. Has held up well for our heavy chewing puppy. It lost a tentacle but that’s nothing compared to the level of destruction our dog has put other toys through in much shorter amounts of time. Recommend for heavy chewers and will likely buy again!

Not large
Color: Green
This is a lot smaller than it appears in pictures. I was going to give it to a large dog but I’m worried it would be a choking hazard. instead I’m going to give it to a pug. Seems fine quality wise just not “large”
