TB500 refers to research-grade thymosin beta-4–derived peptide material used to study actin binding, cell migration, angiogenesis, and tissue remodeling pathways. It is suited for in vitro and in vivo models investigating cytoskeletal regulation and repair-associated signaling, without any approved therapeutic designation.
Thymosin beta-4 (Tβ4) is a 43-amino-acid actin-sequestering peptide; TB500 materials are based on this sequence space and are used as standardized tools in motility and regeneration models.[1] Through defined exposure in cell culture and animal systems, Tβ4-based peptides help elucidate mechanisms governing actin dynamics, directed migration, and extracellular matrix interactions in wound, cardiac, corneal, and other tissues.[2–4] All findings remain exploratory and model-specific.
PubChem records Tβ4 as a highly acidic peptide with strong affinity for G-actin, enabling F-actin/G-actin equilibrium studies and quantitative characterization of cytoskeletal remodeling.[1] TB500-type preparations reproduce key binding motifs, supporting evaluation of actin polymerization, lamellipodia formation, and focal adhesion signaling in a controlled manner.
In fibroblasts, endothelial cells, and keratinocytes, Tβ4-derived peptides have been associated with enhanced migration and reorganization of cytoskeletal and matrix components.[2,3] Researchers employ these reagents to track integrin expression, matrix metalloproteinase activity, and collagen deposition, clarifying peptide-responsive pathways involved in structural repair.
Preclinical models in myocardium, cornea, and dermis use Tβ4-related peptides to study neovascularization, cardiomyocyte survival signaling, and epithelial barrier recovery.[3,4] These experiments delineate molecular targets and pathways but do not establish clinical protocols.
