Tissue Engineering which involve three main component such as scaffold, platelet-rich plasma (PRP) and cells is expected to support in bone regeneration. Gelatin hidrogel scaffold is planted have a function as cell environment and PRP provide growth factor to support differentiation of cells. The success of tissue engineering is affected by number of PRP which is contained in scaffold. The purpose of this study is to compare the incorporation process between impregnated and drop method to gelatin hidrogel scaffold. PRP was prepared from three donors of whole blood, and twice sentrifugation by 450 rcf for 5 minutes and 1500 rcf for 7 minutes. PRP was incorporated into 3 gelatin hidrogel scaffolds for each methods. The remnant of PRP which didn’t incorporate were calculated the number of platelet with giemsa stainning. Platelet which loaded were the reduction result of number platelet before incorporate with platelet remnant. Data of the result were analyzed using independent sample t test. Result show the significant was 0.262 (p&gt;0.05) there’s no significane different between impregnated and drop method for incorporating PRP into gelatin hidrogel scaffold. The number of platelet which incorporated in gelatin hidrogel scaffold were effected by characteristic of scaffold such as structure, interface adherence, porosity and swelling ability. The good characteristic of scaffold could be obtain from synthesis and good fabrication technique.
