Growth factors are proteins in the body that regulate cellular growth and proliferation and also promote cellular differentiation. They are naturally occurring molecules that bind receptors on cell surfaces. Growth factors are important signaling molecules for regulating the cell cycle. They also mediate tissue repair mechanisms when cells have become damaged. Many growth factors are quite versatile, stimulating cellular division in numerous different cell types; while others are specific to a particular cell-type. In life science research, growth factors are often used to study signaling pathways. Growth factors are also sometimes used as cell culture media supplements. Alfa Aesar offers a variety of commonly used growth factors for life science research applications. Our growth factors are high purity proteins and have excellent bioactivity. Many are expressed recombinantly, then aseptically lyophilized and packaged.

  • Erythropoietin alpha, human
    Erythropoietin, or EPO, is a glycoprotein primarily produced in the kidney. It stimulates the proliferation and differentiation of erythroid progenitor cells and is the principal regulator of red blood cell production. Kidney cells increase EPO production in response to hypoxia or anemia.
