"IGF-1
Insulin-like growth factor 1, or IGF-1, is a growth factor that is important for tissue healing. It can stimulate an increase in Type I collagen when added to normal fibroblasts.
One study showed that tenocytes from healthy equine tendon made more Type I collagen relative to Type III collagen when treated with IFG-1 in vitro.[31] The tendon samples had "greater numbers of larger and more metabolically active fibroblasts," and IGF-1 enhanced collagen synthesis in a dose dependant manner. The authors suggest that IGF-1 might help treat horses with tendinosis. A growth factor that helps promote Type I collagen relative to Type III collagen in tendon is certainly worth more study for its potential use in treating tendinosis.
Several other studies showed that a combination of IGF-1 and platlet-derived growth factor increased the rupture force, stiffness, and breaking energy in rat medial collateral ligaments.[32,33] Also, one study showed that treating injured rat Achilles tendons with IGF-1 reduced the "maximal functional deficit" and the "time to functional recovery."[34] Another study showed that IGF-1 and IGF-II stimulated collagen, proteoglycan, and DNA synthesis in a dose-dependent manner in rabbit flexor tendon in vitro.[35]
IGF-1 was not one of the growth factors tried in the previously mentioned carpal tunnel syndrome study[1], so it would be interesting to discover its effect on cells from tendinosis patients.
GDF-5
Growth and differentiation factor 5, or GDF-5, has been linked to tendon healing in several studies. One study showed that the tensile strength of healing rat tendons increased in a dose-dependent manner when treated with GDF-5.[36] Another study showed that GDF-5 deficiency caused mouse tail tendon to have a 17% increase in the proportion of medium diameter collagen fibrils at the expense of larger diameter fibrils, as well as a 33% increase in irregularly-shaped polymorphic fibrils.[37] These structural differences did not cause major differences in biomechanical properties of the tendon, but did cause the fibers to relax 11% more slowly than controls during time-dependent stress/relaxation tests. More research would be needed to see if GDF-5 could play a role in the treatment of tendinosis.
CDMP-2
One research group has investigated the potential for treating tendon injuries with cartilage derived morphogenetic protein, or CDMP-2.[25] This protein is a member of the TGF-beta super family. The researchers treated injured rat Achilles tendons with injections of CDMP-2 and found that the treated tendons were 39% stronger than controls after 8 days. The tendons were also mechanically loaded during healing because the researchers suspected that loading would help the CDMP-2 induce tendon-like tissue instead of bone or cartilage tissue. (The abstract didn't say if the control tendons were also mechanically loaded; if not, the improved healing could be from the loading rather than from the CDMP-2. Presumably, they loaded both the controls and the treated injuries.)
TGF-beta1
Transforming growth factor beta1, or TGF-beta1, is a growth factor important in wound and tissue healing. It has been associated with excessive scar tissue formation in some cases. A group of researchers studied the effect of reducing TGF-beta1 because they were looking for a way to reduce the adhesions and scar tissue that commonly form between the site of injured hand flexor tendon and the surrounding tissues.[26,27] These adhesions reduce normal range of motion. Injured rabbit flexor tendons treated with neutralizing antibody to TGF-beta1 had approximately twice as much range of motion as the controls after 8 weeks of healing. This research might not have direct implications for treating tendinosis, but it does show that sometimes lowering growth factors can lead to better healing; more is not always better when it comes to growth factors.
BMP-12
Bone morphogenic protein 12, or BMP-12, has been shown to improve tendon healing; researchers found that in vivo gene therapy delivery of BMP-12 caused a two-fold increase in tissue strength and stiffness of healing chicken tendons.[38] See the section below "Gene Therapy." "
