LRP1 Mediates the IGF-1-Induced GLUT1 Expression on the Cell Surface and Glucose Uptake in MĆ¼ller Glial Cells

The authors investigated whether Insulin-like Growth Factor-1 (IGF-1) modulates glucose transporter type 1 (GLUT1) traffic to plasma membrane (PM) and glucose uptake, as well as the involvement of Low-density lipoprotein Receptor-related Protein-1 (LRP1) in this process in the human MĆ¼ller glial-derived cell line.

Human Mesenchymal Stem Cells Promote Ischemic Repairment and Angiogenesis of Diabetic Foot through Exosome miRNA-21-5p

Exosomes were isolated from MSCs using ultracentrifugation, and further characterized by the nanoparticle tracking analyzer and flow cytometry. RNA sequencing, Western Blot, in vitro cell proliferation, in vivo pro-angiogenesis, as well as ischemic repairment of diabetic foot through rat model were performed to evaluate exosome physiological functions.
