How they differ

BPC-157 is a short amino acid chain. Animal studies have described its effects on soft tissue healing, including tendon and muscle models. TB-500 is a synthetic form of thymosin beta-4 (Tβ4), and its 17-23 fragment is responsible for actin binding. In vitro work has observed the role of Tβ4 in the migration of endothelial cells and fibroblasts.

KPV is a tripeptide and the C-terminal fragment of alpha-MSH. Thymosin Alpha-1 is a 28-amino-acid peptide studied for its role in T-lymphocyte maturation. As an IRR receptor agonist, ARA-290 shows no erythropoietic activity, and B7-33 is a single-chain analogue of relaxin-2, selective for the RXFP1 receptor.

Research models

Wound healing and angiogenesis

Animal models have described healing of skin, tendon and muscle after mechanical injury. In vitro, endothelial cells formed vessel-like structures.

Cell migration

Filling a tissue defect depends on cell migration. The scratch assay measures how quickly a cell-free gap closes under the influence of TB-500.

Inflammation and immunity

KPV is studied in inflammation models and LL-37 in innate immunity models. Thymosin Alpha-1 has been tested in clinical trials and is registered as a medicine in some countries. B7-33 is studied in fibrosis models.

Working with the reagent
