How to use

In Vitro:

Cibinetide (ARA290) enhances the proliferation, migration, and resistance to H2O2-induced apoptosis of endothelial colony-forming cells (ECFCs). Cibinetide (ARA290) is an EPO-analog peptide without hematopoietic side-effects but may have neurotrophic and antidepressant effects.

In Vivo:

After ECFC transplantation to mice with CLI, a single Cibinetide (ARA290) injection enhances the ischemic/non-ischemic ratio of hindlimb blood flow and capillary density after 28 days and the homing of radiolabeled transplanted cells to the ischemic leg 4 h after transplantation. Cibinetide (ARA290; 30 μg/kg, s.c.) prevents progressive worsening of glucose control without affecting body weight of rats. Cibinetide significantly decreases glucose AUCs in IPGTT in GK rats. Low-dosage Cibinetide (35 μg/kg, i.p.) treatment only slightly attenuates the EAE severity in rats. Cibinetide-treating group (70 μg/kg, i.p.) significantly delays the onset, decreases the neurologic severity and shortens the duration of EAE in a dose-dependent way.
