The Studies for the Preparation of Platelet Lysate (PL) and the Effects of Platelet Lysate (PL) on the Proliferations for Microbial and the Human derived cells
… continuously being reported. As PRPgels have an antibacterial effect and PL is considered as a possible substitute material for fetal bovine serum (FBS), these are added to the culture medium. Therefore, this study aimed at understanding the factors that effect on PRP production, proliferation of …
