General description

Pituitary Extract, bovine (PEX) is an extract of bovine pituitary tissue containing growth factors.


Pituitary Extract bovine has been used as a component in the Roswell Park memorial institute 1640 (RPMI-1640) to culture Rb-/- epithelial cells. It has also been used as a component in the Dulbecco′s modified Eagle′s medium (DMEM) for culturing Schwann cells.

Biochem/physiol Actions

Pituitary Extract, bovine (PEX) or BPE is essential for mitotic activity and promotes the growth of several types of mammalian cells. It favors the proliferation of keratocytes culture and bovine knee chondrocytes. BPE helps in the synthesis of collagen and glycosaminoglycans (GAGs) in bovine knee chondrocytes.

In vitro cultivation of primary bovine knee chondrocytes (BKCs), using bovine pituitary extract (BPE) and porous scaffolds composed of polyglycolide (PGA) and 85/15 poly(lactide-co-glycolide) (PLGA), was investigated. Here, BPE was prepared from fresh bovine pituitaries, and cylindrical PGA/PLGA scaffolds with...

Myelinating Schwann cells express distinct sensory and motor phenotypes as defined by their differing patterns of growth factor production (Hoke et al., 2006). The heterogeneous growth factor requirements of sensory and motor neurons, however, suggest that Schwann cell phenotype might...
