 BPC-157, TB-500 Peptides Europe

Thymosin Beta 4, or TB-500 And BPC-157

TB500 is a synthetic version of a naturally occurring 43-amino acid peptide present in nearly all human and animal cells studied.

A 2010 study in the Animals of the New York Academy of Sciences supported TB500’s potential for cardiac muscle repair following injury, eg, after myocardial infarction (heart attack).  Recognizing the limitations of stem cell therapy for this application, TB500 was found to inhibit myocardial cell death, stimulate blood vessel growth, and activate cardiac processes that encouraged the heart to heal following injury.  The investigation showed that TB500 may be the first agent which can actively recover injured cardiac muscle following heart attack.  This is further supported with prior mouse studies in 2004 showing cardiomyocyte migration, survival and repair of myocardial damage.  

 

Filamentous actin (F-actin, or actin) forms polymers that thicken sputum, adversely affecting cystic fibrosis patients.  TB500 was studied in a population of CF patients, showing a dose- and time-dependent decrease in cohesivity of sputum after administration of TB500 when combined with dornase alfa.  The combination therapy showed a 71% improvement in mucociliary transport of mucus, and a 44% improvement in cough transport of mucus.  

 

TB500 is known to stimulate myoblasts and myocytes (muscle generating cells).  Mitochondrial RNA levels of TB500 have been shown to increase following muscle injury, helping to regenerate muscle fibers and address inflammation in the injured location.  The data support muscle injury causing increased local production of TB500, promoting migration of incoming myoblasts to accelerate skeletal muscle regeneration.  

 

BPC 157 (Body Protection Compound-157) is a pentadecapeptide made up of 15 amino acids. The amino acids sequence in BPC 157 is similar to a portion of the human BPC amino acid sequence. Human BPC is found in the gastric juice. Experiments have shown that BPC 157 enhances the healing of wounds, including tendons wounds such as transected Achilles tendons of rats. The aim of this study was to investigate the probable mechanism that BPC 157 utilizes to accelerate the healing process in an injured tendon. The study used two group of tendon explants of which one group was cultured in a BPC 157-containing medium while the other group was cultured in a medium lacking BPC 157. These cultures were thereafter examined for tendon fibroblasts outgrowths. Such outgrowths indicated tendon regeneration.The results revealed that the explants’ outgrowth was significantly accelerated in the culture containing BPC 157 as compared to the culture lacking BPC 157. Also, a MTT assay did show that BPC 157 does not directly affect cellular proliferation in a culture of rat-derived Achilles tendon. However, results also showed that BPC 157 significantly increased the survival of cells under oxidative stress. Furthermore, the Transwell filter migration assay showed that BPC 157 significantly increased in-vitro fibroblast migration in a dose-dependent fashion. Moreover, BPC 157 accelerated the dispersal of the fibroblasts in culture dishes in a dose-dependent manner.

 

Additionally, FITC-phalloidin staining was able to demonstrate that BPC 157 induces F-actin formation in fibroblasts. Likewise, Western blot analysis was able to detect the production and activation of paxillin and FAK proteins. The western blot analysis also showed that BPC 157 increases the extent of phosphorylation of paxillin and FAK proteins without affecting the amounts produced.

 

Thus, it can be concluded that BPC 157 enhances the ex-vivo growth and in-vitro cellular migration of fibroblasts derived from rat tendon explants. Moreover, BPC 157 also increases the probability of a cell surviving under oxidative stress. These actions of BPC 157 are probably mediated by the activation (through phosphorylation) of the proteinic FAK-paxillin pathway.
