RESEARCH

There are no research or clinical studies currently available where both TB-500 and BPC-157 were used in the same experiment or presented in combination, using the same test model. However, below listed are the studies observing the potential action of the individual peptides.

BPC-157 & TB-500 Blend and Tissue Repair

In one study with Tβ4 conducted in 1999,⁽⁹⁾ experimentally wounded murine models were used as subjects, where half the number of murine models were presented with saline and the rest were presented with TB-500 peptide. The main aim of this study was to determine the potential tissue repair action of the peptide. Four days after the experiment, it was reported by the researchers that the murine models presented with TB-500 showed an apparent 41% increment in the re-epithelialization process (i.e., formation of new epithelial cells to resurface the wound). After seven days, the wounds presented with TB-500 had reportedly contracted by at least 11% as compared to the saline wounds. The authors commented that “these results suggest that Tβ4 is a potent wound healing factor with multiple activities…”

In another 2006 clinical trial,⁽¹⁰⁾ 72 test subjects with pressure ulcers were presented with TB-500. The main aim of this randomized, double blind study was to establish the potential of thymosin beta 4 (analogous to TB-500) in ulcer presence. The test subjects were divided into two groups, where one group was presented with placebo for 84 days and the rest were presented daily with various concentrations of the peptide, for up to 84 days. After 84 days, there was an occurrence of wound healing process where the ulcers reportedly exhibited signs of healing.

In a BPC-157 study,⁽¹¹⁾ three experimental murine models were used as subjects where all were experimentally wounded, with either acute or chronic wounds. These murine models were then divided into two groups, where one was presented with a placebo compound and the other was presented with BC-157 peptide. After the experiment, all the murine models were histologically examined, and it was determined that the murine models with BPC-157 exhibited a prominently higher number of collagen and blood vessels formed as compared to the placebo murine models.

BPC-157 & TB-500 Blend and Ligaments

In one study,⁽¹²⁾  the medial collateral ligament (MCL) of the murine models was transected (cut across) during surgery. All the murine models were then presented with a fibrin sealing agent, where some murine models were also presented with thymosin beta 4 (TB-500). Four weeks after the surgery, it was reported by the researchers that the healing tissues in the peptide murine models exhibited apparently evenly formed and spaced collagen cells. The collagen cells formed in the peptide murine models were reportedly wider as compared to the control murine models. Furthermore, the mechanical properties of the regenerating tissues, including the femur-medial collateral ligament-tibia complexes, appeared to be improved in the TB-500 group compared to the control.

Another research article indicated that BPC-157 might play a role in aiding the recovery of connective tissues, potentially by promoting the growth of tendon explants. Interestingly, the study suggested that BPC-157 may possibly enhance the resilience of these cells in the face of oxidative stress. This outcome might be linked to the triggering of F-actin formation, as indicated by FITC-phalloidin staining. BPC-157 also appeared to enhance the in vitro movement of tendon fibroblasts as indicated by a transwell filter migration test. Furthermore, BPC-157 appeared to hasten the dispersion of tendon fibroblasts across culture plates. Additionally, the study delved into the possible role of the FAK-paxillin pathway (a pair of focal adhesion-linked proteins that relay signals following integrins) in conveying the action of BPC-157. Western blot tests hinted that the phosphorylation rates of both FAK and paxillin seemed to rise with BPC 157, yet the overall protein quantities stayed constant.⁽⁸⁾

BPC-157 & TB-500 Blend and Muscle

A study⁽¹³⁾ was conducted on murine models with experimentally injured gastrocnemius muscle complex. These murine models were initially presented with corticosteroids, which reportedly contributed to severe muscular damage in these murine models . These murine models were then divided into two groups, where one was presented with placebo and the other with BPC-157 daily for up to 14 days. After the experiment, it was reported that the BPC-157 murine models appeared to exhibit complete restoration of their gastric muscles along with full ability to function. Whereas, the placebo treated group did not exhibit any apparent change to the damaged muscles.

TB-500 may also have a potential effect on muscle cell regeneration, more specifically on cardiac muscle cells. One study suggests that TB-500 appears to bolster myocardial resilience in conditions of low oxygen, and seemingly fosters angiogenesis, possibly paving the way for cardiac cell repair. Researchers have hinted at a potential process where cardiac fibroblasts transition into cells resembling cardiomyocytes.⁽¹⁴⁾ In the end, the scholars observed that TB-500, when combined with cardiac reprogramming techniques, might collaboratively reduce potential harm to cardiac cells and foster its regeneration by activating inherent cells within the cardiac region. An examination using murine models of coronary artery tying appeared to exhibit results which implied that TB-500 might elevate integrin-associated kinase (ILK) and protein kinase B operations in the heart, possibly boosting early cardiomyocyte endurance and seemingly enhancing heart performance.⁽¹⁵⁾ The experts also suggested that TB-500 might support the movement of myocardial and endothelial cells in the fetal heart and maintains this capability in mature cardiomyocytes.
