Background:
Platelet gel is a source of many soluble proteins that can modulate tissue regeneration. Dermal fibroblasts play an important role in tissue remodeling and wound healing.
Objective:
The study was performed to investigate the influence of platelet gel and its active ingredients on the proliferation of human dermal fibroblasts in vitro.
Methods:
A fibroblast culture was established from a normal human skin biopsy. Platelet gel was prepared from platelet-rich plasma (PRP) following the addition of calcified thrombin solution. Cell proliferation was measured by MTT assay.
Results:
We showed that platelet gel, PRP, and thrombin stimulate the proliferation of dermal fibroblasts, and that stimulation by PRP is dose dependent.
Conclusion:
Platelet gel can be used to treat chronic skin defects.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
