Procedure for obtaining a composition that contains growth factors, which comprises the steps of heat-treating a platelet-rich plasma or the supernatant of a platelet-rich plasma that contains released growth factors in order to increase its temperature, for eliminating the complement and reducing the immuneglobulins present therein, and lyophilizing the plasma or supernatant in order to obtain a final dry composition that can easily be transported, handled and stored, thereby facilitating periodic or chronic treatments with blood compounds. It has been shown that when the final dry composition is resuspended, a once again humid composition is obtained that maintains its biological properties intact.本發明提供一種獲得含生長因子之組成物的方法，其包括對含有釋放的生長因子的富含血小板之血漿或富含血小板之血漿的上清液進行熱處理的步驟以增加其溫度，用以除去補體並且減少其中所出現的免疫球蛋白，以及對血漿或上清液進行冷凍乾燥，以獲得可輕易地被輸送、處理及儲存的最終乾燥組成物，藉此利用血液複合物而促進週期性的或慢性的治療。已顯示當最終乾燥組成物重新懸浮的時候，會再一次獲得維持完整生物特性的潮濕的組成物。
