Porcine placenta extract induced Akt, ERK, and JNK signaling to heighten the osteogenic activity of human osteoblasts

Abstract

Porcine placenta extract (PPE) is an effective pharmaceutical and cosmetic ingredient, despite its high bioavailability. Despite this, only a few studies on the extract's effect on human osteoblast cellular behavior have been conducted. This study used hFOB 1.19 cells to demonstrate the mechanism by which a novel potent osteogenic compound that was discovered by stimulating the growth, alkaline phosphatase secretion, mineralization, and osteogenesis markers of human osteoblast hFOB 1.19 cells resulted in significant increases in extracellular signal-regulated kinase (ERK)1/2, Akt, and c-Jun N-terminal kinase (JNK) phosphorylation. In addition, PPE was discovered to significantly increase in vitro bone formation that may provide the beneficial potential for osteoporosis prevention and treatment.
