To understand the variable efficacy with platelet rich plasma (PRP) treatments for tendon injury, we determined the differential effects of proteinase-activated receptor (PAR)1- or PAR4-activated PRP (PAR1-PRP, PAR4-PRP) from humans on human patellar tendon stem/progenitor cells (TSCs) and tendon healing. We show that PAR1-PRP released VEGF, whereas PAR4-PRP released endostatin. Treatment of TSCs with PAR1-PRP increased collagen I expression and matrix metalloproteinase-1 (MMP-1), but cells treated with PAR4-PRP increased less collagen I and higher MMP-2 expression. The wound area treated with PAR4-PRP formed tendon-like tissues with well-organized collagen fibers and fewer blood vessels, while PAR1-PRP treatment resulted in the formation of blood vessels and unhealed tissues. These findings indicate that differential activation of PRP leads to different effects on TSCs and tendon healing. We suggest that based on acute or chronic type of tendon injury, selective activation of PRP should be applied in clinics in order to treat injured tendons successfully.
In this study, we report that human plantar fascia consists of two distinct tissues with differential structural properties. These tissues also contain stem/progenitor cells with differential biological properties. The mechanobiological responses of these two plantar fascia stem cells also differ in terms of expression of collagen I and IV, non-ligament-related genes, and proinflammatory genes. The production of inflammatory agents (prostaglandin E2, interleukin-6) and matrix degradative enzymes (matrix metalloproteinase-1, matrix metalloproteinase-2) are also different between the two types of plantar fascia stem cells. Based on the findings from this study, we suggest that plantar fasciitis results from the aberrant mechanobiological responses of the stem cells from plantar fascia sheath and core tissues. Our findings may also be used to devise tissue engineering approaches to treat plantar fascia injury effectively.
